Objective

This report presents national

estimates of sexual activity,

contraceptive use, and births among

males and females 15–19 years of age

in the United States in 2002 from the

National Survey of Family Growth

(NSFG). Data are also presented from

the 1988 and 1995 NSFGs, and from

the 1988 and 1995 National Survey of

Adolescent Males (NSAM).

Methods

Descriptive tables of numbers and

percents are presented and interpreted.

Data were collected through in-person

interviews of the civilian

noninstitutionalized population in the

United States. Interviews were

conducted with 7,643 females, 1,150 of

whom were teenagers, and 4,928

males, 1,121 of whom were teenagers.

Results

In 2002, about 47 percent of female

teenagers (4.6 million), and about

46 percent of male teenagers (4.7

million) had had sexual intercourse at

least once. For never-married males,

there was a significant decline from

55 percent in 1995 to 46 percent in

2002. Among never-married females,

for those aged 15–17 there was a

significant decline in the percent

sexually experienced, and for those

aged 18–19 there was no significant

change. Teenagers showed increases

in the use of contraceptives. About 3

out of 4 teens used a method of

contraception at their first intercourse.

About 91 percent of males and

83 percent of females used a method at

their last (most recent) sex. Hispanic

teens are most likely to have a birth

before age 20 and non-Hispanic whites

are least likely, with non-Hispanic black

teens in the middle.

Conclusion

This report documents findings that

may be helpful in understanding trends

in teen birth and pregnancy, and STD

rates.

Teenagers in the United States:

Sexual Activity, Contraceptive

Use, and Childbearing, 2002

by Joyce C. Abma, PhD.; Gladys M. Martinez, PhD.; William D.

Mosher, PhD.; and Brittany S. Dawson, M.P.P., Division of Vital

Statistics

Highlights

+ In 2002, the proportion of

never-married females aged 15–19

who had ever had sexual intercourse

was 46 percent. It declined

significantly for younger teen

females (age 15–17), and stayed

relatively stable for older teen

females (age 18–19) (table 1 and

figures 1 and 2).

+ The percent of never-married males

aged 15–19 who ever had sexual

intercourse declined significantly

between 1995 and 2002, from 55 to

46 percent. Significant declines

occurred among younger and older

male teens and for non-Hispanic

white and non-Hispanic black male

teens (table 1 and figures 1 and 2).

+ Teenagers are delaying sex until

older ages. In 2002, 13 percent of

never-married female teens had had

sex before age 15 (compared with

19 percent in 1995), and 15 percent

of males had done so (compared

with 21 percent in 1995).

+ The vast majority of (never-married)

teenagers had not had intercourse in

the month prior to interview

(72 percent of females and

75 percent of males), but 16 percent

of females and 12 percent of males

had had sex four or more times in

the past month (figure 4).

+ First intercourse was nonvoluntary

for 9 percent of teen females. This

percent was higher among those

who were younger at first

intercourse.

+ When teens were asked how much

they wanted their first intercourse to

happen at the time it did, 13 percent

of females and 6 percent of males

really didn’t want it to happen at the

time, and 52 percent of females and

31 percent of males had mixed

feelings about it.

+ Teen females most commonly have

first sexual partners who are 1 to 3

years older than themselves, and

most commonly, the partner is

someone with whom they are

‘‘going steady’’ as opposed to a

less-involved relationship (for

example, going out once in awhile),

and as opposed to a more-involved

relationship (for example, engaged).

+ Regarding total number of partners

up to the date of the interview,

28 percent of females and 31 percent

of males had had two or more

partners. Teenaged females who

were younger at first sex were much

more likely to have had higher

numbers of total partners (figure 7).

During a shorter time span, the year

preceding the survey, 18 percent of

male teens and 14 percent of female

teens had had two or more partners

(table 11).

+ About one-quarter of teen females

and 18 percent of teen males used

no method of contraception at first

intercourse. The most popular

method at first intercourse was the

condom, with 66 percent of females

and 71 percent of males using this

method at first intercourse. Method

use increases sharply with increasing

age at first sex for females (table 15

and figure 9).

+ Similar to the downward trend in

sexual experience, many of the

patterns of contraceptive use

Page 1
presented in this report are

consistent with the downward trend

in pregnancies and births to teens

observed since 1991, as they

indicate more effective and

consistent use.

‡ Males and females whose first

intercourse occurred in the

mid-nineties through 2002 are

much more likely to be protected

at first intercourse than their

counterparts having first sex

before 1990 (table 17).

‡ Among female teens who ever

had intercourse, ever-use of the

highly effective injectable

method of contraception

(Depo-Proveray and Lunelley)

increased from 10 percent in

1995 to 21 percent in 2002. By

2002, almost all sexually

experienced teen females

(94 percent) had reported use of

the male condom (table 18 and

figure 10).

‡ Among teens who had

intercourse in the 3 months

before the survey or were

‘‘sexually active,’’ increases since

1995 have occurred in the use of

a method at the last intercourse:

83 percent of sexually active

female teens and 91 percent of

sexually active male teens used a

method at last sex. Pill use,

condom use, the use of new

hormonal methods, and the use

of dual methods, have all

increased for sexually active

male and female teens.

+ Differences in contraceptive use by

race and Hispanic origin persisted in

2002:

‡ One quarter of non-Hispanic

black female teens were

unprotected at their most recent

sex compared with 10 percent of

non-Hispanic white females

(table 20).

‡ Non-Hispanic black males had

higher levels of condom use at

first sex than non-Hispanic white

and Hispanic males (table 16).

‡ Hispanic females and males are

less likely to use contraceptive

protection at first sex compared

with non-Hispanic white and

non-Hispanic black males and

females (table 17).

‡ Hispanic and non-Hispanic black

females have higher percents

ever using the injectable method

of contraception (table 19).

+ Teen females are much less likely to

have a birth before reaching age 20

if they used a contraceptive method

at their first sex (figure 11).

Consistent with their lower use of

contraception at first sex, Hispanic

females have the highest probability

of having a birth before the age of

20: 35 percent compared with

12 percent among non-Hispanic

white teenagers (figure 12).

+ Only 12 percent of births to teens

under 18 in the 5 years before the

survey were intended (occurred at

‘‘the right time’’) according to the

mother, compared with 29 percent of

births to mothers 18–19 and

76 percent of births to women aged

25–44 (table 25).

+ The vast majority of teens report

having received formal instruction

before the age of 18 on how to say

no to sex—86 percent of females

and 83 percent of males— and about

two-thirds of teens receive this

instruction before entering high

school (table 26). A smaller share of

teens received instruction on

methods of birth control before age

18: about two-thirds of teens

received this instruction (table 27).

+ Among teens aged 18–19,

50 percent of females and 35 percent

of males had talked with a parent

before they were 18 about methods

of birth control (figure 14).

+ Among the 5.5 million male and 5.2

million female teens who had not

yet had sex, the main reasons for

not yet having had sex was that it

was ‘‘against religion or morals,’’

followed by ‘‘don’t want to get (a

female) pregnant’’ (table 29).

+ Generally, most teens report that

they would appreciate a partner

using a condom; that they would not

be embarrassed discussing it; and

that it would not reduce pleasure.

This positive predisposition parallels

the very high levels of actual

condom use among teens as of 2002

(table 31).

+ Most teens reported that they would

be ‘‘very upset’’ or ‘‘a little upset’’

if they got pregnant (or got a partner

pregnant). These data suggest that

most teens are motivated to avoid

pregnancy (table 32).

Introduction

The Centers for Disease Control

and Prevention’s (CDC), National

Center for Health Statistics

(NCHS), conducts the National Survey

of Family Growth (NSFG), a periodic

survey that collects data on factors

affecting the formation, growth, and

dissolution of families—including

marriage, divorce, and cohabitation;

contraception, sterilization, and

infertility; pregnancy outcomes; and

births. The NSFG is jointly planned and

funded by NCHS and several other

programs of the U.S. Department of

Health and Human Services (see

Acknowledgments).

The NSFG was established and first

conducted by NCHS in 1973. Since

then, the NSFG has been conducted six

times by NCHS—in 1973, 1976, 1982,

1988, 1995, and 2002. In 1973 and

1976 the survey interviewed women

15–44 years of age who were currently

married or had been married; it was

then considered too sensitive to

interview never-married women on these

topics. In 1982, the survey was

expanded to include women 15–44 years

of age regardless of marital status. Thus

the sample began to include all females,

including never-married teenagers.

This report covers the period

beginning in 1988, when the National

Survey of Adolescent Males (NSAM),

conducted by The Urban Institute,

interviewed a national sample of

teenaged males, parallel to the female

teenaged sample in the NSFG. The

NSAM was repeated in 1995, when the

5th cycle of the NSFG was also

conducted. Thus, the 1988 and 1995

NSAM and NSFG data, combined with

the 2002 NSFG, which included males

in addition to its usual female sample,

allows examination of trends of male

and female teens from 1988, 1995, and

Page 2 [ Series 23, No. 24
2002. The primary purpose of this report

is to publish selected data on the sexual

activity, contraceptive use, and

childbearing experience of the national

sample of 15–19-year-old males and

females interviewed in the NSFG in

2002, and to show trends in these

behaviors since 1988 when possible.

Background

This report focuses on factors

related to birth and pregnancy

rates and sexually transmitted

diseases for teenagers in the United

States. Explaining changes in these rates

is central to the mission of the NSFG.

Thus, the collection of data on sexual

activity and contraceptive use is

necessary to help explain these

outcomes. This report updates some of

the findings in a report published in

2001 from the 1988 and 1995 NSFG

and the 1988 and 1995 NSAM (1).

Monitoring sexual activity and

contraceptive use among teenagers is

important due to the health and social

costs of pregnancy, childbearing, and

STDs among the teenaged population.

As a result of the concern with the high

rates of teen pregnancy and birth in the

United States, a large number of

Federal, State, and local programs have

been launched. In addition, substantial

concern has been raised by the threat of

Human immunodeficiency virus or HIV,

and by other sexually transmitted

diseases among young people.

Pregnancies and Births—The U.S.

birth rate for females 15–19 years of

age was 43 births per 1,000 females in

2002, based on birth certificate data

collected in CDC/NCHS’s National Vital

Statistics System (2) (table A). That rate

was higher than a number of other

developed countries in the world. For

example, according to the latest

available data from the UN Population

Division, the teen birth rate in Canada

was 20 per 1,000, about half the U.S.

rate; the rate in Germany was 10 and in

France, 8, less than one-quarter the U.S.

rate (table A).

The U.S. teen birth rate of 43 in

2002, however, represents a 30 percent

decline from the peak rate in recent

years, which was 62 per 1,000 in 1991

(table B). Adding miscarriages and

stillbirths (collected from pregnancy

histories in the NSFG), and induced

abortions (based on national estimates

from the Alan Guttmacher Institute and

on characteristics of abortion patients

collected from States by CDC’s National

Center for Chronic Disease Prevention

and Health Promotion) produces

estimates of age-specific pregnancy

rates. In 2000, the teen pregnancy rate

in the United States was 84.5 per 1,000

females 15–19 years of age, about

27 percent lower than in 1990 (table B)

(3). By age, the teen pregnancy rate for

15–17 year olds declined from 80 in

1990 to 54 in 2000, while for 18–19

year olds the teen pregnancy rate

declined from 162 in 1990 to 130 in

2000.

There were very large variations in

the 2000 teen pregnancy rate by age and

race and Hispanic origin. Birth and

pregnancy rates for non-Hispanic black

or African American and Hispanic or

Latina teens are higher than the national

averages. In 2000, while the pregnancy

rate for non-Hispanic white teens was

57, it was 151 for non-Hispanic black

teens and 132 for Hispanic teens

(table B). The pregnancy rates for

non-Hispanic black and Hispanic teens

were even higher in 1990 (table B).

Sexually Transmitted Diseases—

Weinstock et al ( 2004) recently

estimated that nearly 19 million cases of

STDs occurred in the year 2000, of

which nearly one-half (9 million) were

among persons 15–24 years of age (4).

Chesson et al (2004) estimated the

direct medical costs of these diseases

This report presents data that may

help to understand trends and

differences in rates of birth, pregnancy,

and STDs among teenagers. It is hoped

that the data will be useful in

understanding these and other issues that

affect the health and well-being of

teenagers in the United States.

Strengths and Limitations

of the Data

The data in this report are based

primarily on the 2002 NSFG, and as a

result they have several strengths:

+ First, the data are drawn from

interviews with large national

samples that were interviewed in

comparable ways in 1988, 1995, and

2002.

+ Second, the data from each survey

were processed and coded in ways

to make them as comparable as

possible, so that trends could be

measured as reliably as possible.

+ Third, the NSFG includes all teens

15–19 years of age in the civilian

noninstitutionalized population of

the United States, by virtue of being

a household survey, as opposed to a

school survey.

+ Fourth, the NSFG also includes a

relatively rich array of

characteristics to identify groups in

which these behaviors are more and

less common: for example, race,

age, education of the teenager’s

mother, when the teenagers’ mother

first had a child, and others. The

NSFG also collected a rich array of

data on contraceptive use, sexual

activity, and childbearing

experience.

+ Fifth, the interviews were conducted

in person by professional, trained

female interviewers. Interviewers

were supplied with visual aids, such

as show cards, life-history calendars,

and ‘‘help screens’’ containing

definitions of terms and other

guides. These were used to help

clarify terms and concepts for the

respondent, enhancing the quality of

the data.

+ Sixth, the response rates for the

survey were high—about 80 percent

in 1988, 1995, and 2002. The

response rate for teenagers in 2002

was 81 percent.

The data shown in this report also have

some limitations:

+ Like all survey data, these data are

subject to sources of nonsampling

error. These include interviewer and

respondent factors such as

misunderstanding of questions on

the part of the interviewer or

respondent, nonuniformity in

administration of questions, and bias

due to giving socially desirable

answers. The preparation and the

conduct of the survey were designed

specifically to minimize these

sources of error (6). Since the NSFG

is a cross-sectional survey, it is also

subject to recall error. Questions rely

on respondents’ recall when

reporting on their past experiences.

However, the experiences that are

the focus of this report are likely to

have occurred in the very recent

past to individuals aged 15–19.

+ The NSFG is designed to provide

national estimates by demographic

subgroups; it is not designed to

yield estimates for individual States.

Therefore no State data are available

from this survey.

Methods

The NSFG is based on interviews

that are administered in person by

trained female interviewers in the

selected persons’ homes. The 2002

sample is a nationally representative

multistage area probability sample

drawn from 120 areas across the

country. The sample is designed to

produce national, not State, estimates.

To protect the respondent’s privacy,

only one person was interviewed in each

selected household. In 2002, teenagers

and black and Hispanic adults were

sampled at higher rates than others. For

teenagers, interviews averaged about 60

minutes. The response rate for teenagers

was about 81 percent.

All of the data in this report were

collected by Computer-Assisted Personal

Interviewing, or CAPI. The

questionnaires were programmed into

laptop computers, and administered by

an interviewer, with the exception of

two measures in this report. Questions

concerning whether first intercourse was

wanted or voluntary were collected in a

self-administered portion of the

questionnaire. This Audio ComputerAssisted Self-Interview (ACASI) mode

of interviewing is a more private mode

of data collection because it allows the

respondent to hear the questions and

response choices over headphones, read

it on the screen if so desired, and enter

a response into the computer without the

interviewer knowing what the response

was. This mode of interviewing was

used to ask the more sensitive items in

the survey.

Respondents in the 2002 survey

were offered $40 as a ‘‘token of

appreciation’’ for their participation.

More detailed information about the

methods and procedures of the study is

in the ‘‘Technical Notes.’’ More

complete technical information will be

published in a forthcoming report (6).

Some tables present statistics for all

teenagers and some for teenagers who

have never been married. Teenagers who

have never been married are a

population of particular interest since

they are at risk of nonmarital pregnancy

and childbearing. In addition, to analyze

the time series since 1988, the universe

of teenagers must be consistent for each

survey year, across female and male

teens. In 1988 the NSAM male universe

was limited to never-married teens.

This report shows trends over three

survey cycles: 1988, 1995, and 2002, by

race and Hispanic origin. Standards for

the presentation of data by race and

Hispanic origin have changed over this

time period, but this report relies on a

prior classification that allows

comparison across the three survey

Page 4 [ Series 23, No. 24
cycles. The difference between this

earlier classification and a newer

classification standard involves

individuals who chose more than one

race. In the NSFG, respondents who

identify multiple race categories were

allowed to select one group that best

describes them. The classification used

in this report shows all respondents by

the one race group that they chose, or in

the case of multiple-race respondents, by

the one group that best describes them.

For every table in this report that

presents statistics by race, there was an

analogous table created that presents

statistics according to the newest

classification guidelines (issued by the

Office of Management and Budget, or

OMB). These guidelines require that

those who report more than one race be

presented separately from those who

report only one race. To establish a

baseline for future reports using the new

race classification, data using this

classification are shown on the internet,

at: www.cdc.gov/nchs/nsfg.htm.

Unfortunately, however, the sample sizes

for teenagers in the NSFG are not large

enough to show separate statistics for

those who reported that they had more

than one race origin. See Appendix II,

‘‘Definitions of Terms’’ for more detail

on the classification of race and

Hispanic origin and other terms in this

report. Many tables in this report present

statistics on sexual experience or

activity. All of these statistics refer to

heterosexual vaginal sexual intercourse

only, not other types of sexual activity.

This is noted on the tables as well.

This report is intended to present

some statistics on trends and differences

in the sexual, contraceptive, and

pregnancy experience of teenagers in the

United States through 2002. It is the

first report on teens from the 2002

NSFG, and as such is not intended to be

an exhaustive treatment of this very

complex subject. It also presents

descriptive statistics; it does not attempt

to demonstrate cause-and-effect

relationships.

Results

Sexual Behavior: Trends

and Current Prevalence

Among Teens and

Characteristics of Partners

Sexual experience

Table 1 presents the percent of

never married teens who are sexually

experienced (have ever had heterosexual

vaginal intercourse) for the years 1988,

1995, and 2002. In 2002, 46 percent of

never-married teen females had

experienced sexual intercourse at least

once. Overall, in the 7-year period from

1995 to 2002, the percent of females

aged 15–19 who are sexually

experienced did not change significantly.

As was the case for the trend from 1988

to 1995, this lack of increase is actually

an improvement over the years prior to

1988, when data going back as far as

the early 1970s documented higher

percentages of female teens becoming

sexually experienced with each survey

year (7). However, in the 14-year period

between 1988 and 2002, the percentage

of female teens who were sexually

experienced did decline significantly,

from 51 to 46 percent.

The trends were different, however,

for teens 15–17 and 18–19 years of age.

As figure 1 illustrates, in 2002,

30 percent of female teens aged 15–17

and 31 percent of male teens of this age

range had had sex, down significantly

from their 1995 levels. Figure 2 shows

that, in contrast, the percents sexually

experienced among older female teens

did not decline over the years, while

these percents among older males

declined by about 10 percentage points.

In 2002, about the same percentage

of never-married teen males were

sexually experienced as were females:

46 percent. For males, this represents a

significant decline from 55 percent in

1995, and a 14 percentage point drop

from the 1988 level of 60 percent.

Significant and large declines in the

percent sexually experienced took place

among males of all ages and race and

Hispanic origin groups over the past 7

years. For males 15–17, the decline in

the percent sexually experienced was

12 percentage points; at age 18–19, it

was 11 percentage points. Among

Hispanic teen males the percent declined

Figure 1. Percent of never married females and males 15–17 years of age who have ever

had sexual intercourse: United States, 1988–2002

Series 23, No. 24 [ Page 5
from 61 to 55 percent; among

non-Hispanic white teen males it

declined from 50 to 41 percent; and

most remarkably, non-Hispanic black

teen males’ levels of sexual experience

declined 17 percentage points, from 80

to 63 percent. Some of these groups that

are now showing changes between 1995

and 2002 did not show changes in the

earlier time interval, between 1988 and

1995 (non-Hispanic black and Hispanic

males aged 18–19 years). However, the

youngest male teens and non-Hispanic

black teen males have declines in sexual

experience of fully 19 and 17 percentage

points, respectively, between 1988 and

2002.

These findings on sexual experience

are consistent with those from the Youth

Risk Behavior Survey (YRBS), a

biennial survey of high school students

in the United States, conducted by the

Centers for Disease Control and

Prevention. These teens are in 9th

through 12th grades, and most are

15–17 years of age. The most recent

data show that during 1991–2003, the

percentage of students who had had

sexual intercourse decreased

significantly (8).

Table 2 presents percents who ever

had sexual intercourse, as table 1 did,

but is not limited to never-married teens.

Only small percentages, 2 percent of

female teens, and less than 1 percent of

male teens had ever been married in

2002, so the figures are very similar to

those for never-married teens. In 2002,

among all teen females, 47 percent had

had sexual intercourse at least once.

Among males the percentage was 46.

Age at onset of sexual activity

Table 3 is based on a question

asking for the age at which first

intercourse occurred. The findings

suggest that male teens, and to some

extent female teens, are delaying sex

until older ages, to a greater degree than

7 years ago. The table shows that lower

percents of male and female nevermarried teens had sex before age 15

than was true in 1995. There was a

6 percentage-point drop in each case,

from 21 to 15 percent among males, and

from 19 to 13 percent among females.

For females, this is a turnaround from

an increasing percent between 1988 and

1995. However, the declines become

more modest with increasing age for

females, unlike the case for males,

whose declines remain large at every

age. In 2002, 65 percent of males had

had sex before age 19, down

substantially from 83 percent in 1995.

Frequency of sexual activity

Teens who are sexually

experienced, that is, have had sex at

least once, can vary as to how recently

and how often they have had sex. This

is an important component of risk of

pregnancy and STDs. Table 4 and

figure 3 show that for never-married

teen females, about one-third had had

sex in the past 3 months (were sexually

had sexual intercourse: United States, 1988–2002

Figure 3. Percent of never married females 15–19 years of age who have had intercourse

ever, in the last 12 months, in the last 3 months, and once in their lives, by age:

active). About 41 percent had had sex in

the past year, which is close to the

percent that had ever had sex

(46 percent). A small proportion had had

sex once (4 percent). Teen females aged

18–19 have much higher percents

sexually active than younger teen

females (aged 15–17).

Never-married teen males are very

similar to females in this regard

(table 5). Just under one-third were

sexually active (32 percent), 40 percent

had had sex in the past year, and

4 percent had had sex once. The factors

associated with higher percents sexually

active for females, were associated

similarly for males. The main difference

between males and females involved

race and Hispanic origin: Hispanic and

non-Hispanic black males were more

likely to be sexually active than

non-Hispanic white males, whereas

non-Hispanic white and non-Hispanic

black females were more likely to be

sexually active than their Hispanic

counterparts.

The majority of teens did not have

sex during the month prior to the survey

(table 6 and figure 4): 72 percent of

never-married females and 75 percent of

never-married males did not have sex at

all during the 4-week period. On the

other hand, 9 percent of never-married

females and 6 percent of never-married

males had sex eight or more times

during that 4 week period. Age has a

clear association with frequency of sex.

Older teens, both male and female, had

sex more frequently than younger teens:

in the month prior to the survey

12 percent of 18–19-year-old

never-married males had sex eight or

more times, compared with just

1 percent among the 15–17 year olds.

These percentages for females are

18 percent for the older and 4 percent

for the younger females. A much higher

percent of younger teens did not have

sex at all in the 4-week period.

Appendix III, table I is provided for

the reader’s reference as an alternative

to table 6. This table also presents the

frequency of intercourse in the past 4

weeks, except that it is limited to those

who had ever had sex or the ‘‘sexually

experienced’’ subpopulation of teens.

Thus it highlights this risk factor for

those who can be considered already at

higher risk, having initiated sexual

intercourse.

The next several tables present

information on the circumstances of first

sexual intercourse, characteristics of first

partners, and numbers of partners within

different timeframes, for both females

and males.

Non-voluntary first intercourse

National data have documented that

for a small percentage of teens, first

intercourse is not voluntary (9–11). The

NSFG Cycle 6 provides an update of

this phenomenon and can be compared

with the same measure from the 1995

survey. Table 7 shows that in 2002,

among females aged 18–24 who had

first sex as a teen, 10 percent

experienced nonvoluntary first sex. This

percentage has not changed since 1995

for the overall teen female population.

Consistent with earlier findings, first

intercourse that occurs at an earlier age

is more likely to be nonvoluntary:

18 percent of those whose first sex was

at age 14 or younger, reported that it

was nonvoluntary, compared with

5 percent among those whose first sex

was at 17–19 years old.

The Cycle 6 survey ascertained not

only whether first sex was voluntary or

not voluntary, but also the degree to

which it was wanted by the respondent

(table 8). This question allowed

respondents to choose from ‘‘didn’t

really want it to happen at the time’’; ‘‘I

had mixed feelings— part of me wanted

it to happen at the time and part of me

didn’t’’ and ‘‘I really wanted it to

happen at the time.’’ This is ascertained

for both males and females in Cycle 6.

This was also asked of females in Cycle

5, but respondents chose a number on a

scale of 1 to 10 corresponding to how

much first intercourse was wanted.

Among females aged 18–24 whose

first sex was before age 20, 13 percent

‘‘didn’t really want it to happen at the

time,’’ 52 percent had mixed feelings,

and 33 percent ‘‘really wanted it to

happen at the time.’’ As with the

voluntary vs. nonvoluntary

classification, this distribution is very

different depending on the age at first

sex. For those who had first sex at 14

years or younger, more than a quarter

(27 percent) really didn’t want it to

happen, compared with only 5 percent

among those who delayed first sex to

age 18 or 19. On the other hand, a

nontrivial percentage of those whose

first sex was at age 14 or younger

(18 percent) really wanted it to happen

at the time. First sex with a partner

Figure 4. Percent of never married females and males 15–19 years of age by frequency of

intercourse in the last 4 weeks: United States, 2002

Series 23, No. 24 [ Page 7
closer in age to the female is more

likely to be wanted at the time.

Males have higher percents overall

reporting ‘‘I really wanted it to happen

at the time’’ to describe their first sexual

intercourse. Figure 5 illustrates the male

and female differences across the

wantedness categories. Among males

aged 18–24 years old, whose first sex

was before 20 years of age, 59 percent

of males reported really wanting it to

happen at the time, while 31 percent

reported mixed feelings and only

6 percent reported not really wanting it

to happen. Very small percentages of

males chose this ‘‘least wanted’’

category, across all demographic and

partner-age subgroups. Age of the

female partner shows no clear

association with wantedness of first sex

for males.

For a better understanding of the

two measures, it is helpful to examine a

cross-tabulation of wantedness of first

intercourse by voluntary status.

Appendix III, tables II and III show this

cross-tabulation for females, aged 18–24

whose first intercourse was before age

20 (only females were asked both

questions). For example, table II shows

about one-half of those who didn’t

really want intercourse to happen at the

time it did also reported it was

voluntary. Table III shows the same

cross-tabulation, but presents percents

for wantedness, by voluntariness: among

females aged 18–24 whose first

intercourse was before age 20 and was

reported to be not voluntary, 74 percent

didn’t really want it to happen at the

time and 21 percent had mixed feelings.

Partner characteristics

About 74 percent of teen females

had a first male sexual partner who was

the same age, or 1 to 3 years older, than

they were; only 8 percent had a first

partner who was 6 or more years older

(table 9). The majority of teen females,

75 percent, had first sex with someone

with whom they were ‘‘going steady’’

(table 10). Most other teen females had

first sex with someone they were less

involved with: 14 percent had first sex

with someone they had just met or were

‘‘just friends’’ with, and 7 percent were

‘‘going out once in awhile.’’ Only very

small percentages had their first sex

with a cohabiting partner, fiancé, or

husband. Hispanic teen females had the

highest percents in this category, having

had first sex with a cohabiting partner,

fiancé, or husband (14 percent).

The younger a female is at first sex,

the more likely it is to be with someone

she is not regularly involved with. Of

teen females whose first sex was at age

14 or younger, 33 percent had ‘‘just

met,’’ were ‘‘just friends with,’’ or were

‘‘going out with once in awhile’’ with

their first partner compared with only

11 percent of those who were 17, 18, or

19 at first intercourse.

Number of partners

During the year prior to the survey,

29 percent of teen females had sex with

only one partner (table 11). Only

4 percent had sex with four or more

partners. Similar to female teens,

22 percent of male teens had sex with

just one partner (table 12), and 4 percent

had sex with four or more partners over

the past year. For both male and female

teens, older age was associated with

much higher percentages having had

multiple partners over the past year

(figure 6). Only 1 percent of females

aged 15–17 had four or more partners in

the past year compared with 8 percent

among females aged 18–19.

Many teens have had intercourse

with more than one partner in their life

(tables 13 and 14 and figure 7):

28 percent of females and 31 percent of

males had had more than one partner by

the time of the interview. However, only

6 percent of females and 7 percent of

males had had sex with seven or more

partners. Not surprisingly, younger age

at first sex leads to higher numbers of

partners, if only because those who

begin having sex at an earlier age have

more time to accumulate partners.

Figure 8 shows the magnitude of the

differences by age at first intercourse.

Among females whose first sex was

under 15 years of age, one-quarter had

had sex with seven or more partners by

the time of the interview. This is in

contrast to only 7 percent among those

whose first sex was at age 17, 18, or 19

(also see table 31 in reference 9). This

demonstrates the importance of age at

first sex for its impact on the level of

sexual risk behaviors among teens.

Contraceptive Use Among

Teenagers

The next several tables show

findings on several different aspects, or

measures, of contraceptive use among

teenagers: use at first intercourse,

ever-use, use at the most recent

intercourse, and dual or combination

Figure 5. Percent of males and females 18–24 years of age at interview who had their first

intercourse before age 20, by how much they wanted their first intercourse to happen when

it did: United States, 2002

Page 8 [ Series 23, No. 24
use. These tables are limited to teens

who have ever had vaginal intercourse.

Contraceptive use at first

intercourse

Table 15 shows females 15–19

years of age who have ever had

intercourse, by their use of contraception

at their first intercourse. Of all females

15–19 years of age, 26 percent did not

use any method at their first intercourse.

The proportion not using any method at

first intercourse was 35 percent among

those who had their first intercourse

before age 15, and 17 percent among

those who had their first intercourse at

age 17–19 (figure 9).

Table 16 shows males 15–19 by

their use of contraception at their first

intercourse. Condom use was reported

by 71 percent of males and 18 percent

did not use any method. Non-Hispanic

black teens were more likely than other

groups to report condom use at first sex,

and Hispanic males were more likely to

report no method use. Ten percent of

male teens overall reported use of both

hormonal methods and the condom at

first sex and Hispanic males were less

likely than other groups to report this.

Table 17 shows all men and women

aged 15–44 by their use of

contraception at their first premarital

intercourse. More than one-third of

respondents (37 percent) reported using

no method at first premarital intercourse

and nearly one-half of men and women

(49 percent and 45 percent, respectively)

used a condom. Respondents whose first

premarital sex occurred more recently

were much less likely to report use of

no method: 13 percent of males and

21 percent of females reported no

method use at first premarital sex in

1999–2002, while 61 percent of males

and 57 percent of females reported using

no method at first sex before 1980. Dual

method use has also become more

common in recent years; for females

having their first premarital intercourse

in 1999–2002, 17 percent used the

condom and a hormonal method.

Ever-use of contraceptives

Table 18 shows females 15–19

years of age who have ever had sexual

intercourse and the percent who have

used each of several methods of birth

control in the 1995 NSFG and the 2002

NSFG. Nearly all teens who have ever

had intercourse (98 percent in 2002 and

96 percent in 1995) have used at least

one method of birth control. The most

common methods in 2002 were the

condom (used by 94 percent), and the

pill (used by 61 percent). The injectable

methods, primarily Depo-Proveray, had

been used by 21 percent of sexually

experienced teens in 2002. Looking at

the trends shown in table 18, several

could be related to the decline in the

teen birth and pregnancy rates between

1995 and 2002. The percent who had

ever used the pill increased from

52 percent in 1995 to 61 percent in

2002; the percent who had ever used the

very effective injectable methods

increased from 10 to 21 percent; and

8 percent had used emergency

contraception, the use of high-dose oral

Figure 6. Percent of females 15–19 years of age by number of male sexual partners in the

last 12 months, by age: United States, 2002

Figure 7. Percent of males and females 15–19 years of age, by number of sexual partners

in their lifetimes: United States, 2002

Series 23, No. 24 [ Page 9
contraceptives shortly after intercourse.

Because emergency contraception as a

means of preventing pregnancy was

relatively new in 1995, numbers of teens

using it were understandably small and

do not reach levels of precision required

in this report to present estimates.

Table 19 and figure 10 show data similar

to those in table 18, but this time for

race and Hispanic origin groups and for

2002 only. The proportion of these

females who had ever used the oral

contraceptive pill was 68 percent among

non-Hispanic white teens, 55 percent

among non-Hispanic black teens, and

only 37 percent among Hispanic teens.

In contrast, however, 18 percent of

non-Hispanic white teens had ever used

injectable contraception compared with

27 percent of non-Hispanic black and

24 percent of Hispanic teens.

Contraceptive use at most

recent intercourse

For never-married females aged

15–19 who had sexual intercourse in the

3 months before the interview, table 20

shows the percent who used a method

of birth control at the most recent (last)

sexual intercourse. In 2002, 83 percent

of these female teens used a method at

their most recent intercourse: 34 percent

used the pill, 54 percent the condom,

and 20 percent used both the condom

and the pill (or another hormonal

method).

Note that the percent that used the

condom increased from 38 percent in

1995 to 54 percent in 2002, and the

percent that used dual methods

increased from 8 percent in 1995 to

20 percent in 2002. These data are

another indication that teen

contraceptive use appears to have

increased markedly between 1995 and

2002.

Table 21 shows never-married males

who had sexual intercourse in the 3

months before the interview. It shows

similar findings to those in table 20.

Most importantly, the proportion using

no method at all at last intercourse

dropped from 18 percent in 1995 to

9 percent in 2002. There is evidence that

dual use also rose, but that rise occurred

only among non-Hispanic white male

teens, from 18 percent in 1995 to

30 percent in 2002. Another distinct

trend was the large increase in the use

of the condom to 71 percent in 2002,

continuing an upward trend also seen in

analysis of prior surveys of males (12).

Also of note is that the percent using

the condom as reported by males is

considerably larger than that reported by

females. This gender difference in

reporting use of the condom has been

found in other surveys as well (13). One

possible factor partially explaining this

difference is that females’ partners are

typically older than the females

themselves, and condom use among

males tends to decrease with increasing

age (see, for example, reference 14).

Table 22 shows, for males and

females 15–24 years of age, the

Figure 8. Percent of females 15–19 years of age by number of sexual partners in their

lifetimes, by age at first sex: United States, 2002

percent who used no method, the condom, or the pill at their first intercourse, by age at

first intercourse: United States, 2002

Page 10 [ Series 23, No. 24
consistency of their condom use in the 4

weeks before the interview. Nearly

48 percent of males 15–24 years of age

reported that they used condoms

consistently in the last 4 weeks

compared with 31 percent of females

aged 15–24 (table 22).

Table 23, however, shows

consistency of condom use over a

longer time—the last 12 months. The

proportion using a condom consistently

over the past 12 months was 35 percent

for never-married males compared with

25 percent for never-married females

(table 23).

Births To Teens,

Wantedness of Births, and

Instruction on Sex and

Contraception

Births and wantedness of births

The NSFG 2002 data show that the

probability of a teen female having a

birth before age 20 is 18 percent. As

expected, the probability of having had

a birth increases with age. In 2002, the

probability of young females aged

15–24 having had a birth by age 15 was

1 percent compared with 18 percent by

age 20 (table 24). Among those who did

not use contraception at first sex, the

risks are higher and the increase is

sharper (figure 11).

As has been widely documented,

adolescents’ mother’s characteristics also

influence their timing of a first birth

(15). For young females whose mother

also had an adolescent birth, 32 percent

had a birth before age 20 compared with

only 11 percent of those whose mother

delayed childbearing until after age 20.

The same relationship holds true for

mother’s level of education. In addition,

having lived with both biological

parents at age 14 had a positive impact

on delaying age at first birth. Only

15 percent of young females who lived

with both parents had a first birth before

age 20 compared with 26 percent of

those who had other living

arrangements.

Race differences in the probability

of having had a first birth by the end of

each adolescent year are very dramatic.

Non-Hispanic white youth had the

lowest risk of having a birth at each

age. Hispanics, on the other hand, had

the highest risk of having a teen birth.

Non-Hispanic black teens’ probability of

having had a first birth between the ages

of 15 and 19 were much higher than

Non-Hispanic white teens but lower

than those for Hispanics. Only

12 percent of non-Hispanic white teens

had a first birth by age 20 compared

with 27 percent of Non-Hispanic black

teens and 35 percent of Hispanics

(figure 12).

The majority of teen births are

unintended at the time of conception,

according to prior estimates (16).

Series 23, No. 24 [ Page 11
Table 25 shows the wantedness status of

births to women aged 15–44 by the

woman’s age at the birth. This table

shows results consistent with prior

findings: births to teen females were

more likely to be unwanted (not wanted

then or at any time in the future) and

much more likely to be mistimed

(occurred too soon) at the time of

conception, compared with births to

women aged 20 and over. Among births

to teens, 22 percent were unwanted at

the time of conception compared with

only 12 percent of births to women

25–44 years old. More than one-half,

57 percent, of births to teens were

mistimed, while only 12 percent of those

to women aged 25 to 44 were mistimed

(figure 13). This pattern is even more

striking for births to younger teens

(those occurring to teens aged 17 or

younger). Among births to younger

teens, those who were 17 or younger,

26 percent were unwanted and

62 percent mistimed.

When asked ‘‘How much sooner

than you wanted did you become

pregnant?’’ referring to mistimed

pregnancies (leading to live births in the

past 5 years), teens reported greater

numbers of months and/or years ‘‘too

soon.’’ Thirty-five percent of births to

teens occurred 3 or more years too soon,

while this figure for births to women

aged 20–24 was only 10 percent, and for

births to women aged 25 to 44, only

2 percent. Among non-Hispanic black

teens, a higher percent of births were

unwanted compared with non-Hispanic

white and Hispanic teens. The three

races/Hispanic origin teen groups were

similar, however, in their percents

having mistimed and intended births.

Instruction and communication

on sex and birth control

Teenagers in the survey were asked

several questions about instruction on

topics related to sex and contraception.

Table 26 shows the percent of males and

females 15–19 years of age in 2002 who

received formal instruction before the

age of 18 on ‘‘How to say no to sex.’’

The vast majority of teens receive such

instruction at some point before age 18,

with less than one-fifth of both males

and females reporting not receiving it.

About two-thirds of teens receive this

type of formal instruction before

reaching their high school years. Only

about 6 percent of females and 4 percent

of males reported receiving this

instruction in 10th through 12th grades,

while about 18 percent of females and

23 percent of males reported receiving it

in elementary grades (1st through 5th).

Examining age cohorts, there appears to

be a trend of younger teens receiving

more instruction before age 18 on how

to say no to sex than their older

counterparts.

Instruction on methods of birth

control is less frequently received, at

least before age 18, as shown by

table 27: about one-third of both male

and female teens report not receiving

formal instruction on contraceptive

methods before age 18. A small percent

of teens report being taught about

methods of birth control in elementary

school (1st–5th grade); about one-third

of teens in middle school (6th–8th

grade); and about a quarter of males and

nearly 30 percent of females in high

school (9th–12th grade). Across race and

Figure 12. Probability of a first birth by age 18 and by age 20, among females 15–24 years

of age, by race and Hispanic origin: United States, 2002

Figure 13. Percent of births in the 5 years prior to interview, by wantedness status and age

at birth: United States, 2002

Page 12 [ Series 23, No. 24
ethnic groups, non-Hispanic whites

appear to receive more instruction on

contraception, particularly among males:

about 45 percent of non-Hispanic black

and 38 percent of Hispanic males

reported not receiving this instruction

before age 18 compared with 31 percent

of non-Hispanic white males.

Table 28 and figure 14 illustrate the

percent of teenagers in 2002 who had

talked to their parents before age 18

about selected topics related to sex and

birth control. The majority, about

70 percent, of female and male teens

have talked to a parent about at least

one of the topics before age 18. Females

are more likely than males to talk to

their parents about how to say no to sex,

methods of birth control, and where to

get birth control. This table also presents

the percent of teens who have ever

taken a pledge to remain a virgin. About

11 percent of males and 13 percent of

females have taken a virginity pledge.

Table 29 shows responses of teens

who have never had sex to a question

asking for their reasons for not having

had intercourse yet. The teens were

shown six possible reasons: ‘‘Against

religion or morals’’; ‘‘Don’t want to get

pregnant’’; ‘‘Don’t want to get a

sexually transmitted disease’’; ‘‘Haven’t

found the right person yet’’; ‘‘In a

relationship, but waiting for the right

time’’; and ‘‘Other.’’ The most frequent

reason given for not having had sex is

that it is ‘‘against (my) religion or

morals’’; 38 percent of teen females and

31 percent of teen males chose this as

their main reason. For males and

females, the reason ‘‘don’t want to get

(a female) pregnant’’ was the second

most common reason chosen, followed

by ‘‘haven’t found the right person yet.’’

Teens were least likely to choose ‘‘in a

relationship, but waiting for the right

time’’ as the reason for not having had

sex.

Younger teens more frequently

reported concern about not wanting to

get a sexually transmitted disease, while

older teens more frequently cited that

they had not found the right person yet.

Examining differences by race and

ethnicity, non-Hispanic white teens were

more likely to report that having sex

would be against their religion or

morals, while Hispanics more frequently

reported concern about getting (a

female) pregnant and non-Hispanic

black teens were more concerned than

other groups about getting a sexually

transmitted disease.

Attitudes About Premarital

Sex, Parenthood, Marriage,

Cohabitation, and Condom

Use

Attitudes of teenagers about sexual

activity, nonmarital childbearing, and

cohabitation are described in table 30.

Most teens felt that any sexual act

between two consenting adults is okay:

about 73 percent of both males and

females ‘‘agree’’ and ‘‘strongly agree’’

with the statement. About two-thirds

agree that it is okay for unmarried 18

year olds to have sex if they have strong

affection for each other, but only about

one-third felt the same for 16 year olds.

More females (65 percent) than males

(50 percent) agreed or strongly agreed

that nonmarital childbearing is okay.

Concerning marriage and cohabitation,

most teens agree that ‘‘it is better for a

person to get married than to go through

life being single’’ and disagree with a

statement saying that cohabitation is not

okay. Finally, one-half of females and

slightly fewer males disagree that

‘‘divorce is usually the best solution

when a couple cannot work out their

marriage problems.’’

Teenagers in the survey were also

asked about their feelings toward

condom usage. As shown in table 31,

the vast majority of teens (83 percent of

males and 91 percent of females)

reported a ‘‘pretty good’’ or ‘‘almost

certain’’ chance they would appreciate if

a condom were used during intercourse

and ‘‘a little’’ or ‘‘no chance’’ that it

would be embarrassing to discuss using

a condom with your partner. Athough

most teens reported a ‘‘50–50 chance’’

or less that using a condom would

diminish physical pleasure, males were

less likely to report ‘‘no chance’’

(15 percent among males compared with

35 percent among females). Females

were more likely to report ‘‘an almost

certain chance’’ they would appreciate if

their partner used a condom.

Finally, table 32 depicts teenagers’

attitudes about what it would be like to

get (a female) pregnant at the time of

the survey. One-half of males and

Figure 14. Percent of males and females 18–19 years of age who talked with a parent

before age 18 about ‘‘How to say no to sex’’ ‘‘Methods of birth control,’’ and ‘‘Sexually

Transmitted Diseases:’’ United States, 2002

Series 23, No. 24 [ Page 13
three-fifths of females reported they

would be ‘‘very upset’’ if this happened,

and most of the remainder reported they

would be ‘‘a little upset,’’ as opposed to

‘‘a little pleased,’’ ‘‘very pleased,’’ or

‘‘wouldn’t care.’’ Younger teens, teens

who have never had sex, teens living

with both biological or adoptive parents

at age 14, and non-Hispanic whites were

more likely than other groups to report

they would be very upset. Hispanic

females were more likely than other

females to feel very pleased, as were

males whose age at first sex was less

than 15 years.

Conclusion

The data in this report show

several trends among teenagers in

the United States and some

important patterns in 2002. Comparing

data from 2002 with data for 1995, the

percent sexually experienced declined

for most teens, particularly for male

teens and younger (age 15–17) female

teens. Compared with 1995 findings,

teens in 2002 were delaying sex until

older ages. Teens were more likely in

2002 to use contraception at first sex

and at most recent sex than in 1995 and

are more likely to have used highly

effective methods such as injectable

contraception. Teens’ use of the condom

continued to increase through 2002.

Using the (male) condom in

combination with a hormonal

contraceptive has become much more

prevalent than it was in 1995. These

findings are consistent with estimates

from the national vital statistics system

that show a consistent decrease in the

rate of teenage pregnancy and

childbearing since the early 1990s.

Studies using earlier data have found

that reductions in sexual activity and

increases in the use of contraceptives

have played a role in this decline (17).

Racial and ethnic differences

persist, with Hispanic females and

non-Hispanic black males having higher

percents sexually experienced than

non-Hispanic white teens, despite large

declines for both groups since 1995. All

groups showed marked increases in

contraceptive use at first and most

recent sex. However, Hispanic male and

female teens and non-Hispanic black

male and female teens had higher

percents unprotected at first intercourse.

Non-Hispanic black female teens had

higher percents unprotected at most

recent intercourse. However, nonHispanic black and Hispanic teen

females also had higher percents using

injectable contraceptives than

non-Hispanic white teens.

Most teens have received instruction

on how to say no to sex and methods of

birth control. Most teens want to avoid a

pregnancy and have attitudes toward

condom use that are consistent with

being likely to use them.

These are some of the notable

findings in this report that is intended to

present some basic statistics related to

teen sexual activity, contraceptive use,

and childbearing. Further analyses can

use the rich array of measures in the

NSFG to shed further light on the

important issues of teen birth, teen

pregnancy, and sexually transmitted

diseases among youth.

Technical Notes on

Methods

Sample Design and

Fieldwork Procedures

The 2002 National Survey of

Family Growth, or NSFG, was based on

12,571 interviews with men and women

15–44 years of age in the civilian

noninstitutionalized population of the

United States. The interviews were

administered in person by trained female

interviewers in the selected persons’

homes. The 2002 sample is a nationally

representative multistage area

probability sample drawn from 120

areas across the country. The sample is

designed to produce national, not State,

estimates. Persons were selected for the

NSFG in five major steps: + Large areas (counties and cities)

were chosen first.

+ Within each large area or ‘‘Primary

Sampling Unit,’’ groups of adjacent

blocks— called segments—were

chosen at random.

+ Within segments, addresses were

listed and some addresses were

selected at random.

+ The selected addresses were visited

in person, and a short ‘‘screener’’

interview was conducted to see if

anyone 15–44 lived there.

+ If so, one person was chosen at

random for the interview and was

offered a chance to participate.

To protect the respondent’s privacy,

only one person was interviewed in each

selected household. In 2002, teenagers

and black and Hispanic adults were

sampled at higher rates than others.

The NSFG questionnaires and

materials were reviewed and approved

by the CDC/NCHS Research Ethics

Review Board (formerly known as an

Institutional Review Board or IRB), and

by a similar board at the University of

Michigan. The female questionnaire

lasted an average of about 85 minutes.

All respondents were given written and

oral information about the survey and

were informed that participation was

voluntary. Adult respondents 18–44

years of age were asked to sign a

consent form but were not required to

do so. For minors 15–17 years of age,

signed consent was required first from a

parent or guardian, and then signed

assent was required from the minor. The

response rate for the survey was about

79 percent. For teenagers, the response

rate was 81 percent.

Over 200 female interviewers were

hired and trained by the survey

contractor, the University of Michigan’s

Institute for Social Research, under the

supervision of NCHS. Interviewing

occurred from March of 2002 until the

end of February 2003. All of the data in

this report were collected by ComputerAssisted Personal Interviewing, or

CAPI. The questionnaires were

programmed into laptop computers, and

administered by an interviewer.

Respondents in the 2002 survey were

offered $40 as a ‘‘token of

appreciation’’ for their participation.

More detailed information about the

methods and procedures of the study

will be published in a forthcoming

report. (6).

Two variables that are usually

included in analyses of sexual risk

behaviors because of their strong

associations are education and poverty

level. They are not included in this

report due to the fact that this report

focuses on teens. Education is not useful

because among teens it is a ‘‘proxy’’ for

age, and poverty level is not reliably

reported by teens. Mother’s education is

included as an indicator of family

socioeconomic status.

Standard errors were calculated, and

tests of significance performed, for

selected comparisons in this report. The

statistical package SUDAAN (www.rti.org/sudaan) was used for the

calculation of standard errors, since it

takes into account complex sample

designs such as that of the NSFG.

Significance across time points was

determined by a two-tailed test for

proportions, permitting an assumption of

unequal variances. Significance is noted

in footnotes in the tables on which tests

were performed. Lack of comment on a

comparison does not mean that

significance was tested and ruled out.

Appendix II

Definitions of Terms

This appendix defines the terms

corresponding to data from the 2002

NSFG. The definitions of measures from

the 1995 and 1988 NSFG and the 1995

and 1998 NSAM, can be found in

Appendix II, p. 52, of ‘‘Sexual Activity

and Contraceptive Practices Among

Teenagers in the United States, 1988

and 1995,’’ a prior report in this series

published in 2001(1). That report also

contains a table presenting wording of

questions on sexual behavior and

contraceptive use from each of the

surveys in each of the years (table XV,

p. 21). These definitions are sorted

alphabetically within two groups: 1) the

sexual activity, contraceptive use, and

childbearing measures, and 2) the

demographic characteristics and family

background measures.

Sexual Activity,

Contraceptive Use, and

Childbearing Measures

Age at first sexual intercourse—Age at

first sexual intercourse is defined as the

respondents’ age when he or she first

had heterosexual, vaginal intercourse.

(Female recode VRY1STAG): In the

female questionnaire, it was based

primarily on the following question:

‘‘Thinking about the very first time

in your life that you had sexual

intercourse with a man, how old

were you?’’

In cases where the respondent refused to

provide or did not know the age, but did

provide the date of first intercourse, it

was based on this date. Respondents

who did not know their age at first

intercourse were allowed to estimate

their age (that is: between 15 and 18 or

between 18 and 20) and this estimate

was used when age and date were

missing.

(Male recode=VRY1STAG): For males

the information could come from one of

several different places in the

questionnaire. If the respondent’s first

sex was with a partner within the past

12 months, the date of the first (or only)

sex with that partner was used to

calculate his age. If the respondent’s

first sex was with his wife or cohabiting

partner, the date of the first sex with

that partner was used to calculate his

age. Respondents whose first sex was

with a partner from before the 12

months prior to the interview were

asked:

‘‘That very first time that you had

sexual intercourse with a female,

how old were you?’’

These respondents were allowed to

respond to questions estimating the age,

if the exact age was unknown, as in the

female questionnaire.

Age of first male partner—(Female

recode = FSEXPAGE): This measure is

based primarily on a direct question

asking:

‘‘How old was your first partner

when you had sexual intercourse

with him that first time?’’

If the respondent did not know or

refused to report the first male partner’s

age, she was asked to estimate his age

relative to hers by choosing one of the

following categories ‘‘1–2 years older,’’

‘‘3–5 years older,’’ ‘‘6–10 years older,’’

‘‘more than 10 years older,’’ ‘‘the same

age,’’ ‘‘1–2 years younger,’’ ‘‘3–5 years

younger,’’ ‘‘6–10 years younger,’’ or

‘‘more than 10 years younger.’’

Consistency of condom use in the past

4 weeks—For females, this was

determined by two questions: one asking

for the number of times the respondent

had sex in the past 4 weeks (see

definition for ‘‘Frequency of sex in the

past 4 weeks’’) and another question

asking for the number of those times a

condom was used. For those who had

only had sex once, this question was

worded simply:

‘‘Did you use a condom?’’

For those who had had sex more than

once, the question was:

‘‘How many of those times did you

use a condom?’’

For males, the measure was determined

in the same way. See definition for

‘‘Frequency of sex in the past 4 weeks’’

for males. Following the question about

frequency of sex, males were asked:

‘‘And, in the last 4 weeks, how

many of the times that you had

sexual intercourse with a female did

you use a condom?’’

The percent was calculated for females

and males by: (number of times had

sex/number of times used the

condom)*100

Consistency of condom use in the past

12 months—For females, this was

directly asked, with the question:

‘‘Please look at card 48. Thinking

back over the past 12 months, that

is, since (date of 12 months prior to

interview date), would you say you

used a condom with your partner

for sexual intercourse every time,

most of the time, about half of the

time, some of the time, or none of

the time?’’

The middle three categories were

collapsed to result in the category

‘‘some of the time’’ in the table. For

males, the measure is determined from a

different type of question. Males were

asked directly for the percent, with the

question:

‘‘During the last 12 months, what

percent of the time that you and she

had sex together did you use a

condom?’’

The percent was then converted to the

simple three-category format, with

0=‘‘None of the time,’’ 1–99%=‘‘Some

of the time,’’ and 100%=‘‘Every time.’’

This was asked for the male’s wife or

cohabiting partner, and for up to three

nonmarital, noncohabiting partners in

the past 12 months. Thus, if a male had

more than one partner in the past 12

months, the responses were combined to

arrive at the final category out of the

three. If he used the condom 100% of

the time with all partners, this was

coded ‘‘Every time,’’ and if he used the

condom 0% of the time with all

partners, this was coded ‘‘None of the

time.’’ Any other combination was

coded ‘‘Some of the time.’’ For

example, if he used the condom 100%

of the time with one partner and 0% of

Page 42 [ Series 23, No. 24
the time with another partner, this was

coded ‘‘Some of the time.’’ If he used

the condom 50% of the time with one

partner and 0% of the time with another

partner, this was also coded ‘‘Some of

the time.’’

Contraceptive use at first sexual

intercourse—This variable is defined

only for women who have ever had

intercourse. The recodes used are

SEX1MTHD1–4, which describe

whether any method was used the first

time a woman had intercourse, and if

so, what method(s). If she did report

using a method at first intercourse, she

was asked what method she used and

what other method(s) she used at the

same time, if any.

Contraceptive use at last sex in the 3

months prior to interview—(Female

recode = MTHUSE3, METH3M1-

METH3M4): This is defined for

respondents who had sex in the past 3

months. For most respondents, it is

based on direct questions about method

use with the last partner in the past 12

months, worded:

‘‘Looking at Card 33, the last time

you had intercourse with [name of

partner] in [date of last sex with

him], did you or he use any

method?’’

and

‘‘Which method or methods on Card

33 did you use?’’

If the respondent’s only partner in the

past 3 months was her first partner ever,

and she had only had sex with him

once, method use is taken from recode

SEX1MTHD1, which is described for

the measure ‘‘Contraceptive use at first

sexual intercourse.’’

(Male recode = METH3M1-

METH3M4): This is defined for

respondents who had sex in the past 3

months. This is determined from one of

two different question formats. The

NSFG contained an experiment in which

30 percent of male respondents received

one question format and 70 percent of

male respondents received another

question format. The 30 percent group

was asked:

‘‘Please look at Card 45. That time

that you had sexual intercourse with

(partner’s name), did you or she use

any methods to prevent pregnancy

or sexually transmitted disease?’’

while the 70 percent group was asked:

‘‘Please look at Card 46. That time

that you had sexual intercourse with

(partner’s name), did you, yourself,

use any methods to prevent

pregnancy or sexually transmitted

disease?’’

The two question formats were

combined to result in the final measure

used here. The measure could be

reflecting the male’s responses about his

wife or cohabiting partner, or a

nonmarital, noncohabiting partner,

depending on who he last had sex with

in the past 3 months.

See Appendix II, p. 52, of reference #1,

for definitions of this measure from the

1995 NSFG and the 1995 NSAM.

Ever had sexual intercourse—(Female

recode = HADSEX) and (Male recode =

HADSEX): This was ascertained from a

single question in the male and female

questionnaires, asked of respondents

who had never been pregnant (females)

and had never cohabited or been

married:

(Male questionnaire):

‘‘Have you ever had sexual

intercourse with a female

(sometimes this is called making

love, having sex, or going all the

way)?’’

(Female questionnaire):

‘‘At any time in your life, have you

ever had sexual intercourse with a

man, that is, made love, had sex, or

gone all the way’’?

Ever-use of birth control methods—

These data are based on a series of

questions that begins as follows:

‘‘Card 30 lists methods that some

people use to prevent pregnancy or

to prevent sexually transmitted

disease. As I read each one, please

tell me if you have ever used it for

any reason. Please answer yes even

if you have only used the method

once.’’

Have you ever used birth control

pills?

Have you ever used condoms or

rubbers with a partner?

Have you ever had sex with a

partner who had a vasectomy?

Have you ever had sex with a

partner who used withdrawal or

‘pulling out’?

Have you ever used Depo-Provera

or injectables (or shots)?’’

This series of questions was asked for a

total of 19 different contraceptive

methods.

Frequency of sex in the past 4 weeks—

For both males and females, this

measure is based on the direct question:

‘‘Now please think about the last 4

weeks. How many times have you

had sexual intercourse with a

male/female in the last 4 weeks?’’

Had sex in the 3 months prior to the

interview—(Female recode =

SEX3MO): For females, this measure is

constructed from her report of the date

of last sex with her last sexual partner.

If this date was within 2 months of the

date of interview, the respondent is

counted as having had sex in the past 3

months. This measure differs from that

available in prior cycles of the NSFG,

but is comparable to the analogous

measure for males in this report. See

table XV, p. 78, of ‘‘Sexual Activity and

Contraceptive Practices Among

Teenagers in the United States: 1988

and 1995,’’ for the definition of this

measure from prior cycles. This

alternative measure is also available for

Cycle 6, and is called ‘‘SEXP3MO.’’

(Male recode = SEX3MO): For males,

this measure is constructed similarly to

that of the females. It is constructed

from his report of the date of last sex

with either his most recent nonmarital,

noncohabiting sexual partner, or from

the date of last sex with his wife or

cohabiting partner. The respondent is

counted as having had sex in the 3

months prior to the interview if this date

Series 23, No. 24 [ Page 43
was within 2 months of the date of

interview.

Had sex in the 12 months prior to the

interview—(Female recode=

PARTS1YR): For females, this was

based primarily on a question asking:

‘‘During the last 12 months, that is,

since (date), how many men, if any,

have you had sexual intercourse

with? Please count every male

sexual partner, even those you had

sex with only once.’’

(Male recode = SEX12MO): For males,

this measure is constructed identically to

the male measure for sex in the past 3

months, except that the respondent is

counted as having had sex in the prior

12 months if the date of last sex with

the last partner was within 11 months

prior to the month of interview.

Had sex once—(Female and male

recode=SEXONCE): If the response to

the direct question:

‘‘Have you had sexual intercourse

more than once?’’

is ‘‘yes,’’ or the respondent has ever

been married or has ever cohabited, then

the respondent is counted as having had

sex more than once. Otherwise, she/he

is counted as having had sex only once.

How much first sexual intercourse was

wanted—In the self-administered part of

the questionnaire, both male and female

respondents 18–44 years of age who had

ever had intercourse read on the

computer screen (or heard over

headphones) the following question:

‘‘Think back to the very first time

you had vaginal intercourse with a

(person of the opposite sex). Which

would you say comes closest to

describing how much you wanted that

first vaginal intercourse to happen?’’

I really didn’t want it to happen at

the time.......1

I had mixed feelings—part of me

wanted it to happen at the time and

part of me didn’t.......2

I really wanted it to happen at the

time.....3

Instruction on Sex and contraception—

The survey asked males and females

15–19 years old whether they ever had

any formal instruction before the age of

18, on how to say no to sex and about

methods of birth control. In addition,

they were asked what grade they were

in when they received this instruction.

Nonvoluntary first sexual intercourse—

In the Audio Computer-Assisted

Self-Interviewing (ACASI) part of the

questionnaire, the question described

above on ‘‘How much first intercourse

was wanted’’ was followed by this

question:

‘‘Would you say then that this first

vaginal intercourse was voluntary

or not voluntary, that is, did you

choose to have sex of your own free

will or not?’’

The answer categories were ‘‘voluntary’’

and ‘‘not voluntary.’’ This wording is

the same for the years 1995 and 2002.

This question was asked in the

interviewer-administered portion of the

questionnaire in 1995.

Number of partners in lifetime—

(Female recode = LIFPRTNR): This is

based on a direct question worded:

‘‘Counting all of your male sexual

partners, even those you had

intercourse with only once, how

many men have you had sexual

intercourse with in your life?’’

If the respondent reported ‘‘don’t

know,’’ she could then estimate a range

of number of partners, providing the low

and high numbers of the range. The

measure was assigned the low number

in these cases. If the respondent refused

to report the number, the measure was

assigned to 0.

(Male recode = LIFPRTNR): The

construction of this measure was based

on a variable that was based primarily

on a question worded:

‘‘How many different females have

you ever had intercourse with? This

includes any females you had

intercourse with, even if it was only

once or if you did not know her’’

and under certain circumstances, on a

direct question worded:

‘‘Altogether, how many different

females have you ever had

intercourse with? This includes any

female you had intercourse with

even if it was only once or if you

did not know her well.’’

If the respondent did not know or

refused to report the number of lifetime

partners and had ever been married or

ever cohabited, then the measure is

assigned the total number of wives and

cohabiting partners.

Number of partners in past 12

months—(Female recode =

PARTS1YR): For females, this was

based on a question asking:

‘‘During the last 12 months, that is,

since (date), how many men, if any,

have you had sexual intercourse

with? Please count every male

sexual partner, even those you had

sex with only once.’’

(Male recode = PARTS1YR): This

measure for males is based on a variable

that represents number of female sex

partners in the last 12 months and a

direct question worded:

‘‘Altogether, how many different

females have you had sexual

intercourse with in the past 12

months?’’

If a respondent only had one partner in

his lifetime, it is based on the question:

‘‘You said that you had sexual

intercourse with a female once in

your life. Was that in the last 12

months?’’

Male respondents who were married or

cohabiting were assigned a value of 1.

Relationship with partner at first

intercourse—Female respondents who

had ever had intercourse were asked,

‘‘At the time you had sexual

intercourse with your first partner,

how would you describe your

relationship with him?’’

They were shown a card that had the

following categories on it:

+ Married to him

+ Engaged to him

+ Living together in a sexual

relationship, but not engaged

+ Going with him or going steady

+ Going out with him once in a while

Page 44 [ Series 23, No. 24
+ Just friends

+ Had just met him

+ Something else

Wantedness of births—For this report,

pregnancies that ended in a live birth

within 5 years prior to the interview

date were classified as ‘‘intended,’’

‘‘mistimed,’’ or ‘‘unwanted.’’ A

pregnancy was classified as ‘‘intended’’

if, right before the pregnancy began, the

woman wanted to become pregnant at

that time or earlier.

Births from pregnancies that were

wanted eventually, but occurred sooner

than desired, have been classified as

‘‘mistimed.’’ For example, if a woman

wanted to have her first child at age 22,

but became pregnant at age 17, her

pregnancy was classified as mistimed. A

pregnancy was classified as ‘‘unwanted

at conception’’ if the woman had

become pregnant at a time when she

had not wanted to have a(nother) baby

ever. For example, if she wanted to have

two children in her life and became

pregnant with a third child, that

pregnancy was classified as unwanted.

Pregnancies that ended in multiple

births have been counted only once

because only the pregnancy, a single

event, was judged as intended/unwanted/

mistimed.

Demographic and

Parental/Family

Background Measures

Age—(Female and Male recode =

AGER) In this report, age is classified

based on the respondent’s age as of the

date of the interview. Sampled persons

were eligible for the 2002 NSFG if they

were 15–44 years of age.

Education of Respondent’s mother—

‘‘Mother’s education’’ is based on the

recode EDUCMOM, ‘‘mother’s (or

mother-figure’s) education.’’ It is based

on two questions in the interview:

‘‘Who, if anyone, do you think of as

the woman who mostly raised you

when you were growing up?’’

(The respondent was shown a series of

categories including ‘‘Biological

mother’’ and others.) and:

‘‘Please look at Card 17. What is

the highest level of education (she/

your mother) completed?’’

+ Less than high school

+ High school graduate or GED

+ Some college but no degree

+ 2-year college degree

+ 4-year college graduate

+ Graduate or professional school

Women were classified into four

categories: less than high school; high

school graduate or GED; some college,

but less than a 4-year degree; and 4-year

bachelor’s degree or higher.

Family structure at age 14—(Female

and male recode=INTCTFAM): In the

2002 NSFG, respondents were asked,

‘‘Between your birth and your 18th

birthday, did you always live with

both your biological mother and

biological father?’’

and:

‘‘Were your biological parents

married to each other at the time

you were born?’’

(The question wording was modified

slightly if the respondent was still under

age 18 or had never lived away from

parents or parent figures.) If the answer

was ‘‘yes,’’ then the teen was classified

as living with both parents at age 14. If

the answer was ‘‘no,’’ then the

respondent was asked,

‘‘Now, think about when you were

14 years old. Looking at Card 10,

what female and male parents or

parent-figures were you living with

at age 14?’’

Nine categories were shown on the card,

including no parent or parent-figure

present, biological mother or father,

stepmother or father, and others.

Living arrangements—This variable

refers to living arrangements at the time

of interview and is based on information

on the relationship to the respondent of

every member of the household at the

time of the survey. If two biological or

two adoptive parents are present in the

household, the respondent is classified

as living in a ‘‘parental home: intact.’’ If

one biological parent is present, either

by him/herself or along with any other

parents or parent-figures, or only

nonbiological parent-figure(s) are

present, the respondent is classified as

living in a ‘‘parental home: not intact.’’

All other households, which by

definition contain no parents or

parent-figures, are classified as

‘‘nonparental.’’ The low sample sizes for

this latter category preclude the

presentation of statistics separately for

them.

Marital status at interview—(Female

and male recode=RMARITAL)—This

variable is based on the following

question in the interview:

‘‘Now I’d like to ask about your

marital status. Please look at Card

1. What is your current marital

status?’’

+ Married

+ Not married but living together with

a partner of the opposite sex

+ Widowed

+ Divorced

+ Separated because you and your

spouse are not getting along

+ Never been married

In this report, the categories

‘‘widowed,’’ ‘‘divorced,’’ and

‘‘separated’’ were not shown separately

because of limitations of sample size.

These categories were combined and

labeled as ‘‘formerly married.’’

(Respondent’s) Mother’s age at first

birth—(Female and male

recode=AGEMOMB1) Respondents

were asked,

‘‘Including yourself, how many

children did your mother have who

were born alive to her?’’

(The question wording was tailored if

the respondent was adopted.) Then they

were asked:

‘‘How old was she when she had

her first child who was born

alive?’’

Follow-up questions were asked for

respondents who were not sure of

the exact age.

Race and Hispanic origin—(Female

and male recode=HISPRACE):

Respondents were classified as

‘‘Hispanic,’’ ‘‘non-Hispanic white,’’

Series 23, No. 24 [ Page 45
‘‘non-Hispanic black,’’ or ‘‘non-Hispanic

other race,’’ based on two other recoded

variables, HISPANIC and RACE. All

respondents who answered ‘‘yes’’ to the

following question were coded as

‘‘Hispanic:’’

‘‘Are you of Hispanic or Latino, or

of Spanish origin?’’

The RACE recode was based on

responses to the following question:

‘‘Which of the groups (below)

describe your racial background?

Please select one or more groups.’’

The race groups shown were:

+ American Indian or Alaskan Native

+ Asian

+ Native Hawaiian or Pacific Islander

+ Black or African American

+ White

Up to four groups could be coded.

Respondents who identified themselves

with more than one race group were

asked to select one group that best

describes them, and the RACE and

HISPRACE recodes reflected this

response. Because of limited sample

size, Asian, Pacific Islander, Alaskan

native, and American Indian women are

not shown in this report; these groups

are, however, included in the totals of

all tables.

New OMB guidelines on the

classification of race require statistical

reports to separate those who reported

only one race from the small proportion

of the population who reported more

than one race. Large data sets such as

the U.S. Census, the National Vital

Statistics System, and some very large

surveys can produce reliable statistics on

mixed-race respondents. Unfortunately,

the NSFG’s sample size of 12,571

respondents does not yield reliable

statistics for very small subgroups such

as mixed-race respondents. However, to

establish a baseline for future reports

using the new race classification, data

using this classification are shown on

the internet at www.cdc.gov/nchs/

nsfg.htm

Interpretation of data by race and

Hispanic origin—Data are shown by

race and Hispanic origin in the tables

because NCHS is frequently asked to

provide data separately for white, black,

and Hispanic persons. Race is associated

with a number of indicators of social

and economic status. Measures of

socioeconomic status (for example,

education and income) are not always

available for the point in time when the

event being studied occurred. While

characteristics such as education and

income change over time, race and

ethnicity do not change, so they can be

used at all points in time as proxies for

socioeconomic status. Differences

among white, black, and Hispanic

women in the phenomena presented in

the tables are most likely due to the

lower income and educational levels of

black and Hispanic women, (U.S.

Census Bureau, Statistical Abstract

2003, tables 227, 228, 684, 687, 697)

their limited access to health care and

health insurance (18), the communities

in which they live (19), and other

factors.
