by Joyce A. Martin, M.P.H.; Brady E. Hamilton, Ph.D.; Michelle J.K. Osterman, M.H.S.; Sally C. Curtin, M.A.; and T.J. Mathews, M.S., Division of Vital Statistics



# Abstract Objectives— This report presents 2012 data on U.S. births according to a wide variety of characteristics. Data are presented for maternal age, live-birth order, race and Hispanic origin, marital status, attendant at birth, method of delivery, period of gestation, birthweight, and plurality. Birth and fertility rates are presented by age, live-birth order, race and Hispanic origin, and marital status. Selected data by mother’s state of residence and birth rates by age and race of father also are shown. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. Methods— Descriptive tabulations of data reported on the birth certificates of the 3.95 million births that occurred in 2012 are presented.

### Results— A total of 3,952,841 births were registered in the United States in 2012. The general fertility rate declined to 63.0 per 1,000 women aged 15–44. The teen birth rate fell 6%, to 29.4 per 1,000 women. Birth rates declined for women in their twenties and increased for women aged 30–44. The total fertility rate (estimated number of births over a woman’s lifetime) declined 1% to 1,880.5 per 1,000 women. The rate of births to unmarried women declined; the percentage of births to unmarried women was essentially stable at 40.7%, but the number of births to unmarried women increased slightly. The cesarean delivery rate was unchanged at 32.8%. The preterm birth rate declined for the sixth straight year to 11.55%; the low birthweight rate declined slightly to 7.99%. The twin birth ratewas stable at 33.1 per 1,000 births; the rate of triplet and higherorder multiple births dropped 9% to 124.4 per 100,000 total births. **Keywords:**birth certificate • maternal and infant health • birth rates • maternal characteristics 

# Highlights

• A total of 3,952,841 births were registered in the United States in 2012, slightly fewer births (749) than in 2011. Births declined 1% for non-Hispanic white and Hispanic women and were essentially unchanged for non-Hispanic black women from 2011 to 2012.

• The 2012 general fertility rate declined to 63.0 births per 1,000 women aged 15–44, another historic low for the United States. The total fertility rate declined 1%, to 1,880.5 births per 1,000 women in 2012.

• The birth rate for teenagers aged 15–19 dropped 6% from 2011 to 2012, to 29.4 per 1,000—the lowest rate ever reported for the United States. Rates were down for age groups 15–17 and 18–19, and for nearly all race and Hispanic origin groups.

• Birth rates declined among women in their early twenties between 2011 and 2012 to a record low. The rate was also down for women aged 25–29, but it increased for women aged 30–44. Birth rates for the youngest (under age 15 years) and the oldest (aged 45 and over) mothers were unchanged.

• The mean age of mother at first birth rose again, to 25.8 years in 2012, up from 25.6 years in 2011.

• The 2012 U.S. cesarean delivery rate was unchanged at 32.8%. The cesarean rate rose nearly 60% from 1996 to 2009, declined slightly from 2009 to 2010, and has been stable since.

• The birth rate for unmarried women fell for the fourth consecutive year in 2012 to 45.3 per 1,000 unmarried women aged 15–44. The percentage of births to unmarried women was unchanged from 2011 at 40.7%, but the number of nonmarital births increased slightly, by less than 1%, to 1,609,619.

• The preterm birth rate (less than 37 weeks) declined for the sixth straight year, to 11.55% of all births in 2012, down 2% from 2011 and 10% from the 2006 peak. Rates declined for non-Hispanic white and non-Hispanic black births and for most maternal age groups from 2011 to 2012.

• The 2012 rate of low birthweight (less than 2,500 grams) was 7.99%, down slightly from 2011 (8.10%) and 3% lower than the 2006 high (8.26%).

• The 2012 twin birth rate was 33.1 per 1,000 total births and was essentially unchanged from 2009–2011. The triplet and higher-order multiple birth rate (triplet/+) dropped 9% in 2012 to 124.4 per 100,000 births and is down by more than one-third since the high in 1998 (193.5); seeFigure 1

# Introduction This report presents detailed data on numbers and characteristics of births in 2012, birth and fertility rates, maternal demographic and health characteristics, place and attendant at birth, and infant health characteristics. A report of preliminary birth statistics for 2012 presented data on selected topics based on a substantial sample (99.96%) of 2012 births (1). In addition to the tabulations included in this report, more detailed analysis is possible by using the natality public-use file issued each year. The data file may be downloaded fromhttp://www.cdc.gov/nchs/data_access/Vitalstatsonline.htm(2). The public-use file does not include geographic detail; a file with this information may be available upon special request (3). A data access and analysis tool, VitalStats, is also available fromhttp://www.cdc. gov/nchs/VitalStats.htm(4). VitalStats includes birth data for 1990 through 2012, with access to interactive, prebuilt tables. Users also can build tables using more than 100 variables from the natality public-use files and geographic information by state and for counties with populations of 100,000 or more. 

# 1989 and 2003 revisions of U.S. Standard **Certificate of Live Birth** This report includes 2012 data on items that are collected on both the 1989 revision of the U.S. Standard Certificate of Live Birth (unrevised) and the 2003 revision of the U.S. Standard Certificate of Live Birth (revised). The 2003 revision is described in detail elsewhere (5,6). Thirty-eight states, the District of Columbia (DC), and three territories implemented the revised birth certificate as of January 1, 2012. The 38 revised states and DC represent 86% of all 2012 U.S. births. The revised reporting areas are: California, Colorado, Delaware, DC, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Washington, Wisconsin, Wyoming, Guam, Northern Marianas, and Puerto Rico. One state, Virginia, implemented the revised birth certificate in 2012, but after January 1. This report presents information on selected data items comparable between the 1989 and 2003 birth certificate revisions. Information on topics comparable between revisions but not presented in this report (e.g., day of birth, month of birth, and congenital anomalies) can be found in the Internet tables (see “List of Internet Tables”) and in the “User’s Guide” public-use file for each data year (2). Recent reports and data releases present information on items not previously available from the National Center for Health Statistics (e.g., use of infertility therapies, WIC food, source of payment for the delivery, maternal morbidity, and breastfeeding) for 2009, 2010, and 2011 (7–11). A recent report also assesses the quality of the 2003 revised medical and health birth certificate data (12)

# Methods Data shown in this report are based on 100% of the birth certificates registered in all states and DC. More than 99% of births occurring in this country are registered (13). Tables showing data by state also provide separate information for Puerto Rico, Virgin Islands, Guam, American Samoa, and Commonwealth of the Northern Marianas. These areas, however, are not included in totals for the United States. Race and Hispanic origin are reported independently on the birth certificate. In tabulations of birth data by race and Hispanic origin, data for Hispanic persons are not further classified by race because the majority of women of Hispanic origin are reported aswhite. Most tables in this report show data for the categories of nonHispanic white, non-Hispanic black, and Hispanic. Data for births are also presented in some tables for American Indian or Alaska Native (AIAN) and Asian or Pacific Islander (API); for specific Hispanic groups Mexican, Puerto Rican, Cuban, and Central and South American; and for other and unknown Hispanic. Data for AIAN and API births are not shown separately by Hispanic origin because the majority of these populations are non-Hispanic. Text references to black births and black mothers or to white births and white mothers are used interchangeably for ease in writing; seeTechnical Notes

. The 2003 revision of the U.S. Standard Certificate of Live Birth allows the reporting of more than one race (multiple races) for each parent (5) in accordance with the revised standards issued by the Office of Management and Budget (OMB) in 1997 (14). SeeTechnical Notesand the “User Guide” (13) for detailed information on the 2012 multiple-race reporting area and methods used to bridge responses to a single race for those who report more than one race. In this report, the total number of births includes births to women up to age 64. In tables that include age of mother, the oldest age group shown (40–54, 45–49, 45–54, or 50–54) includes births to mothers up to age 64. For information on levels of incomplete reporting by state, seeTechnical Notesand the “User Guide” (13). For information on the measurement of data items shown in this report and the Internet tables, imputation techniques used, computation of derived statistics, and definitions of terms, see the “User Guide” (13). Birth and fertility rates for specific Hispanic population groups (Mexican, Puerto Rican, Cuban, Central and South American, and other Hispanic populations) for 2010–2012 are based on population estimates derived from the American Community Survey (ACS), conducted by the U.S Census Bureau. Rates for specific Hispanic population groups prior to 2010 are based on population estimates derived from the Current Population Survey (CPS). For more information about the populations for Hispanic groups, seeTechnical Notesand the 2011 “User Guide” (13). 

# Demographic Characteristics **Births and birth rates** A total of 3,952,841 births were registered in the United States in 2012, 749 fewer than in 2011 (3,953,590) (Tables 1and5;Figure 2). From 2007 through 2011, the number of births declined, falling steadily from 2007 through 2010, but the downward pace slowed from 2010 to 2012 (1). Among the three largest race and Hispanic origin groups, the number of births declined less than 1% for non-Hispanic black



## Figure 2. Live births and general fertility rates: United States, 1920–2012

### 4 National Vital Statistics Reports, Vol. 62, No. 9, December 30, 2013 

### women and 1% for non-Hispanic white and Hispanic women from 2011 to 2012. The number of births also declined for AIAN women (1%) but rose 7% for API women. Among the specified Hispanic groups, births declined less than 1% for Puerto Rican women and 2%–3% for Cuban, Mexican, and Central and South American women between 2011 and 2012. 

## Fertility rate The 2012 general fertility rate (GFR) for the United States was 63.0 births per 1,000 women aged 15–44, down slightly (less than 1%) from the record low rate reported for the country in 2011 (63.2) (Tables 1and5;Figure 2). As with the number of births, the fertility rate declined steadily from 2007 through 2010, but the pace of the decline slowed from 2010 to 2012 (1). The GFR declined for the three largest race and Hispanic origin groups from 2011 to 2012, down less than 1% for non-Hispanic white, 1% for non-Hispanic black, and 2% for Hispanic women. The GFR also declined for AIAN women (1%). However, the rate for API women rose by 4%. Among the specified Hispanic groups, the rate for Mexican women fell 3% from 2011 to 2012, whereas rates for Puerto Rican, Cuban, and other Hispanic women (Central and South American and unspecified Hispanic groups) were essentially unchanged. 

# Age of mother **Teenagers—**The teenage birth rate was 29.4 births per 1,000 women aged 15–19 in 2012, another historic low for the country and down by 6% from 2011 (31.3) (Tables A,3,4,7, and8;Figures 3and 4) (15–18). This rate has fallen by over one-half since 1991 (61.8), when the long-term decline in births to teenagers began (15). From 2011, the number of births to teenagers aged 15–19 declined 7% to 305,388 in 2012, the lowest number since 1945 (280,997) and 41% lower than in 1991 (519,577). Birth rates for teenagers aged 15–17 and 18–19 were 14.1 births per 1,000 for the younger teenagers and 51.4 births per 1,000 for the older teenagers in 2012, down 8% and 5%, respectively, from 2011. Record lows were reached for both younger (15–17) and older (18–19) teenagers. Since 1991, the rate for teenagers aged 15–17 has fallen 63%, and the rate for teenagers aged 18–19 has fallen 45%. The birth rate for the youngest teenagers, aged 10–14, was unchanged (0.4 births per 1,000 in 2012). Among racial and ethnic groups, rates for teenagers aged 15–19 declined for all groups from 2011 to 2012, with declines ranging from 3% for AIAN teenagers to 5% for API, and 6%–7% for non-Hispanic

1Includes births to race and origin groups not shown separately, such as white-Hispanic and black-Hispanic women, and births with origin not stated. 2Race and Hispanic origin are reported separately on birth certificates. Persons of Hispanic origin may be of any race. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. Multiple-race reporting areas vary for 2011 and 2012; see Technical Notes. 3Includes persons of Hispanic and non-Hispanic origin and origin not stated, according to the mother’s reported race; see Technical Notes. 4Includes all persons of Hispanic origin of any race; see Technical Notes.

### white, non-Hispanic black, and Hispanic teenagers. Birth rates for teenagers aged 15–17 also declined for all racial and ethnic groups in 2012; rates for ages 18–19 were down for all groups except for AIAN and API. **Women in their twenties—**The birth rate for women aged 20–24 in 2012 was 83.1 births per 1,000 women in this age group, down 3% from 2011 (85.3) and a record low for the United States (Tables 3,4,7,8, and12;Figure 4). The rate for women in this age group has declined steadily since 2007 at nearly 5% annually. The number of births to women in their early twenties declined 1% from 2011 to 2012, whereas their population rose 2% (17). The rate for women aged 25–29 was 106.5 births per 1,000 women, down 1% from 2011 (107.2). The rate for women in this age group has declined 2% a year since 2008. The number of births to women in their late twenties also declined in 2012, down slightly (less than 1%) from 2011, whereas their population rose slightly (less than 1%). **Women in their thirties—**The birth rate for women aged 30– 34 was 97.3 births per 1,000 women in 2012, up 1% from 2011 (96.5). Both the number of births and the population of women in this age group increased in 2012, by 3% and 2%, respectively. The birth rate for women aged 35–39 was 48.3 births per 1,000 women in 2012, up 2% from the 2011 rate (47.2). The number of births to women aged 35–39 rose 2% in 2012, whereas the population of women in this age group declined 1% (Tables 2,6, andII) (17). **Women in their forties—**The birth rate for women aged 40–44 was 10.4 births per 1,000 women in 2012, up 1% from 2011 (10.3) (Tables 4and8). The rate for women in this age group has risen steadily since 2000 (8.0) by 2% annually (Figure 4). The number of births to women in their early forties rose 1%, whereas their population was essentially unchanged. The birth rate for women aged 45–49 (which includes births to women aged 50 and over) was 0.7 births per 1,000 women in 2012, unchanged since 2008. Births to women aged 45–49 declined 6% from 2011 to 2012, and the population for these women declined 2%. The increase in birth rates for women aged 35 and over during the last 20 years has been linked, in part, to the use of fertility-enhancing therapies (19). **Women aged 50 and over—**Six hundred births occurred to women aged 50 and over in 2012, compared with 585 births in 2011 (Tables 2and6) (17). Since 1997, when data for women aged 50 and over became available again, the number of births to women in this age group has generally increased (from 144 births). In 2012, the birth rate for women aged 50–54 was 0.5 births per 10,000 women, unchanged since 2006 (data not shown in tables). Because of the small number of births to women in this age group, the birth rate for women aged 50–54 is expressed per 10,000 women. For rates shown elsewhere in this report, births to women aged 50 and over are included with births to women aged 45–49 when computing birth rates by age of mother (the denominator for the rate is women aged 45–49)



## . 

# Live-birth order The 2012 first-birth rate for the United States was 25.2 births per 1,000 women aged 15–44, 1% less than the rate in 2011 (25.4) (Tables 3,7, and9). First-birth rates declined for women aged 15–19, 20–24, and 25–29 (by 5%, 2%, and 1%, respectively), whereas rates for women aged 30–34 and 35–39 rose (2% and 3%, respectively). The rates for women aged 10–14 and 40 and over were unchanged. Another useful measure for interpreting childbearing patterns is the mean age at first birth, which is the arithmetic average of the age of mothers at the time of birth and is computed directly from the frequency of first births by age of mother. In 2012, the mean age of mother was 25.8 years, up from 25.6 years in 2011 and from 21.4 years in 1970 (Tables 13,14, andI–1) (18,20,21). The increase in the mean age in 2012 reflects, in part, the relatively large decline in births to women in their teen years and their twenties. Mean age at first birth varied by race and Hispanic origin in 2012, from 22.5 years for AIAN women to 29.3 years for API women. The average ages at first birth for the three largest race and Hispanic origin groups were 23.6 years for non-Hispanic black, 23.8 years for Hispanic, and 26.6 years for non-Hispanic white women (Tables 13 and14). Among the specified Hispanic groups, average ages ranged from 23.2 years for Mexican women to 26.6 years for Cuban women. Average age at first birth increased for women in nearly all race and Hispanic origin groups in 2012. 

# Total fertility rate The 2012 total fertility rate (TFR) for the United States was 1,880.5 births per 1,000 women, 1% below the 2011 rate (1,894.5) (Tables 4,8,13, and14). After generally increasing from 1998 through 2007, the TFR has declined for each of the last 5 years. The TFR estimates the number of births that a hypothetical group of 1,000 women would have over their lifetimes, based on age-specific birth rates in a given year. Because it is computed from age-specific birth rates, the TFR is age-adjusted, and can be compared for populations across time, population groups, and geographic areas. 

## Figure 4. Birth rates, by selected age of mother: **United States, 1990–2012**

### 6 National Vital Statistics Reports, Vol. 62, No. 9, December 30, 2013 

### TFRs declined for nearly all race and Hispanic origin groups in 2012, down 1%–2% for non-Hispanic white, non-Hispanic black, Hispanic, and AIAN women. However, the rate for API women rose 4% from 2011 to 2012. Among specified Hispanic groups, the rate for Mexican and Puerto Rican women fell 3% each; rates for Cuban and other Hispanic women (Central and South American and unspecified Hispanic groups) did not change significantly. The 2012 U.S. TFR remained below “replacement”—the level at which a given generation can exactly replace itself (generally considered to be 2,100 births per 1,000 women). The TFR has been generally below replacement since 1971. With the exception of Hispanic women (reflecting mainly, rates for Mexican and other Hispanic women), the TFRs for all other groups were below replacement (Tables 8and14). 

# Births and birth rates by state The number of births declined between 2011 and 2012 in 7 states (Alabama, Connecticut, Georgia, Illinois, Mississippi, New Hampshire, and New Jersey); increased in 6 states (Arizona, Idaho, Kansas, Louisiana, North Dakota, and Texas); and was essentially unchanged in the 37 remaining states and DC; seeTables 10and11 for 2012 data. Among U.S. territories, the number of births declined for all areas except Guam, where births rose 9% in 2012. The GFR declined in 13 states in 2012 (Alabama, Alaska, Colorado, Connecticut, Florida, Georgia, Illinois, Massachusetts, Mississippi, Nevada, New Hampshire, New Jersey, and North Carolina); increased in 4 states (Idaho, Kansas, North Dakota, and Ohio); and was essentially unchanged in the 33 remaining states and DC. Rates among the states ranged from 50.3 births per 1,000 women aged 15–44 in New Hampshire to 83.1 in Utah (Table 12). The GFR decreased for Puerto Rico and Northern Marianas in 2012, 3% and 15%, respectively; increased for Guam (9%); and was essentially unchanged for American Samoa and Virgin Islands. The TFR declined from 2011 to 2012 for 21 states (Alabama, Alaska, California, Colorado, Connecticut, Delaware, Florida, Georgia, Illinois, Maryland, Massachusetts, Michigan, Mississippi, Missouri, Nevada, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, and Virginia); increased in 1 state (Idaho); and was essentially unchanged in the remaining 28 states and DC. TFRs ranged from 1,592.5 births per 1,000 women in Rhode Island to 2,373.5 in Utah (Table 12). In 2012, the TFR decreased for American Samoa, Puerto Rico, and Northern Marianas; increased for Guam; and was essentially unchanged for Virgin Islands. 

# Birth rates for teenagers by state The birth rate for teenagers aged 15–19 declined between 2011 and 2012 in 29 states and DC and was essentially unchanged in the remaining 21 states (Table B). Declines ranged from 4% for Louisiana to 15% for Delaware. The teen birth rates for the U.S. territories declined for Puerto Rico and Virgin Islands and were essentially unchanged for the remaining areas from 2011 to 2012. Despite declines across all reporting areas in recent years, large differences in teen childbearing persist among the states (22–24). In 2012, teen births rates ranged from 13.8 in New Hampshire to 47.5 in New Mexico (Table 12). The wide range in state-specific teen rates is consistent with patterns observed in previous analyses.

### teen birth rates were lowest in the Northeast and highest across the South and Southwest. Differences in teen birth rates among race and Hispanic origin groups, noted earlier, contribute in part to the variation in state-specific teen birth rates (see “Age of mother”). 

# Births to unmarried women The birth rate for unmarried women declined in 2012 for the fourth consecutive year. The rate fell 2% from 2011 to 2012, to 45.3 births per 1,000 unmarried women aged 15–44, the lowest rate since 2003 (Tables C,15, and16). The nonmarital birth rate was 13% lower in 2012 than in 2007 and 2008, when it was at its historic peak of 51.8 per 1,000. The percentage of all births to unmarried women was 40.7 in 2012, essentially stable for the third consecutive year. The number of nonmarital births rose very slightly from 2011 (1,607,773) to 2012 (1,609,619). The 2012 total is 7% lower than the 2008 peak (Table C). Birth rates for unmarried women fell in 2012 for women in age groups under 30; the rate was essentially unchanged for women aged 30–34, and it increased to historic peaks for women aged 35 and over. The steepest declines were for teenagers, particularly younger teenagers aged 15–17, whose rate dropped by 8% from 2011 (14.9) to 2012 (13.7). Although the majority of nonmarital births are for women under age 25 (54% in 2012), this level has dropped from 64% in 2002 (25). Nonmarital birth rates declined for all race and Hispanic origin population groups except API women, for whom the rate increased by 2%, from 22.4 in 2011 to 22.9 per 1,000 in 2012. Despite this increase, API women had the lowest rate of all race and Hispanic origin groups in 2012. Hispanic women had the highest nonmarital birth rate of all groups in 2012 (72.6) but also the largest percent decline between 2011 and 2012, a 3% drop (from 75.1 in 2011). Rates for non-Hispanic white women (32.1) and black women (62.6) fell 1% and 2%, respectively, in 2012. All race and Hispanic origin groups have experienced declines from the peak rates of 2007– 2008, with the largest decline for Hispanic women, down 29% (from 102.1 in 2007). While the percentage of all births to unmarried women was down slightly in 2012 (40.7) from its peak of 41.0% in 2009, it was still more than twice the level in 1980, 18.4% (Table C). About 9 out of 10 births to teenagers aged 15–19 were nonmarital compared with about 1 in 5 for women in their thirties. Almost two-thirds of births to women aged 20–24 were nonmarital (64.8%)—the age group with the highest number of nonmarital births (593,894). The proportions of nonmarital births vary widely by race and Hispanic origin. In 2012, the percentage of nonmarital births for non-Hispanic black (72%) and AIAN (67%) mothers was more than three times that of API mothers (17%) and more than twice that of non-Hispanic white mothers (29%). A little more than one-half (54%) of births to Hispanic mothers were to unmarried women. These proportions were essentially unchanged from 2011. More than one-half of all births in DC, Louisiana, Mississippi, and New Mexico were to unmarried women in 2012 (Table I–4). Less than one in five births in Utah (18.7%) were to unmarried mothers, the lowest of any state. These geographic variations largely reflect compositional differences by race and Hispanic origin among states. 

# Age of father The 2012 fertility rate of men for the United States was 46.1 births per 1,000 men aged 15–54, unchanged from 2011 (46.1) (Table 17). Rates declined for all men under age 30 (down 6% for men aged 15–19, 4% for men aged 20–24, and 2% for men aged 25–29); rose for men aged 35–49 (up 2% for men aged 35–39 and 40–44 and 4% for men aged 45–49); and were unchanged for men aged 30–34 and 50 and over. Rates for men aged 15–19 (13.8), 20–24 (58.3), and 25–29 (92.5) reached record lows in 2012 (18). Birth rates for white men declined less than 1% to 44.0 births per 1,000 men aged 15–54 between 2011 and 2012; the rate for black men declined 1% to 58.2 births per 1,000 men aged 15– 54—these rates were record lows for both groups. Rates declined for white men in all age groups under 35 and for black men in all age groups under 30, rose for white men aged 35–39 and 45–54 and black men aged 35–49, and were unchanged for the remaining age groups. Information on age of father is often missing on birth certificates of children born to women under age 25 and to unmarried women. In 2012, age of father was not reported for 13% of all births, 23% of births to all women under age 25, and 30% of all nonmarital births. The procedures for computing birth rates by age of father that account for the missing data are described in the “User Guide” (13). **Table C.

# Maternal Lifestyle and Health **Characteristics Medical services utilization**  **Attendant at birth and place of delivery** The vast majority of births in the United States are delivered in hospitals. In 2012, 98.6% of all U.S. births occurred in hospitals. Doctors of medicine attended 85.8% of all hospital births, certified nurse midwives (CNMs) attended 7.6%, and doctors of osteopathy attended 6.0% (Table 20). Out-of-hospital deliveries represented 1.4% of births in 2012. Of the more than 50,000 out-of-hospital births, about two-thirds (65.6%) occurred in a residence (home), and 29.0% occurred in a freestanding birthing center (Table 20). The number of births occurring at home, 35,184, was the highest since reporting began for this item in 1989. Older mothers, those aged 35 and over, are the most likely to have a home birth (26). Oregon reported the highest percentage of home births in 2012 (2.4%), with five other states at 2.0% or more. Six states and DC reported less than one-half of a percentage of births occurring at home; Louisiana had the lowest percentage of home deliveries (0.2%). In 2012, CNMs attended 7.6% of all hospital births, the same as 2011, but a 6% increase from 2005 (7.2%). The percentage of out-of-hospital births attended by CNMs also increased 6% over this period, from 28.6% in 2005, to 30.4% in 2012. 

## Method of delivery In 2012, 32.8% of U.S. births were delivered by cesarean (Table 21), a rate that has remained unchanged since 2010. Prior to 2010, the cesarean delivery rate had increased every year since 1996 when about one-fifth of births (20.7%) were delivered by cesarean. Cesarean delivery rates were unchanged from 2011–2012 for all maternal age groups under 40 (Table 22). Rates for women aged 40–54 increased 1%, from 49.2% to 49.7%. As in prior years, cesarean delivery rates were higher for older mothers. One in two births to women aged 40–54 were delivered by cesarean, compared with less than one in four births to women under age 20. Changes in the cesarean delivery rate from 2011–2012 varied by race and Hispanic origin (Table 21). Rates increased for nonHispanic black (from 35.5% to 35.8%) and Hispanic (32.0% to 32.2%) women. In contrast, the rate for non-Hispanic white women declined from 32.4% to 32.3%; rates for non-Hispanic white women have declined every year since 2009. Historically, Hispanic women have had lower cesarean delivery rates than non-Hispanic white and non-Hispanic black women; however, in 2012, cesarean delivery rates for non-Hispanic white and Hispanic women were essentially the same. Non-Hispanic black women continued to have the highest rate of cesarean delivery. Changes in cesarean delivery rates varied by state (Table I–7). For most states (35 and DC) the cesarean delivery rate remained unchanged from 2011 to 2012. Rates in 9 states were lower in 2012 than in 2011, decreasing an average of 2%. Rates for the remaining 6 states were higher in 2012 than in 2011, increasing an average of

### 4%. Cesarean delivery rates for 2012 ranged from 22.6% in Utah to 40.2% in Louisiana. The American College of Obstetricians and Gynecologists has called for a reduction in the occurrence of nonmedically indicated cesarean delivery and induction of labor prior to 39 weeks (27,28). Efforts to reduce such births include changes in hospital policy to disallow elective delivery prior to 39 weeks (29,30). The rate of cesarean delivery for all U.S. births delivered at less than 39 weeks peaked in 2009 at 38.3% and had declined every year since, reaching 37.5% in 2012 (Figure 5). Declines in the cesarean delivery rate among births at 38 weeks have driven this downward trend. From 2009 to 2012, the cesarean delivery rate at 38 weeks declined at least 2% each year, reaching 32.2% in 2012 (from 34.7% in 2009). In contrast, cesarean delivery among births at 39 weeks continued toincrease at least 2% each year during this time. Changes at other gestational ages were less marked (data not shown). A recent report provides more detail on the recent trends in cesarean delivery at 38 and 39 weeks among singleton births (31). Information for 2012 on primary cesarean and vaginal birth after cesarean delivery for the revised reporting area (38 states and DC) is presented in the “User Guide” (13). An upcoming report will examine trends in primary cesarean delivery rates by state and for limited reporting areas (32). Use of forceps and vacuum extraction to assist delivery has been declining since data on these methods have been available (Table D). In 2012, only 3.40% of births were assisted by forceps or vacuum extraction (down from 3.50% in 2011). In 1990, forceps and vacuum extraction assisted 9.01% of births. Vacuum extraction declined from 2.85% in 2011 to 2.79% in 2012. The use of forceps declined from 0.65% in 2012 to 0.61% in 2012. Forceps have been used for less than 1% of births since 2005. 

# Infant Health Characteristics **Period of gestation** The preterm birth rate declined to 11.55% in 2012, down 2% from 2011 (11.73%) and 10% from 2006 (12.80%); seeTables E, 23, and24. The percentage of infants born preterm (less than 37 completed weeks of gestation) rose by more than one-third from 1981 through 2006, but is down each year during 2007–2012. Declines from 2011 to 2012 were observed among infants born early preterm (less than 34 weeks), from 3.44% to 3.41%, and among late preterm infants (34–36 weeks), from 8.28% to 8.13%. Since 2006, the early preterm rate is down 7%, and the late preterm rate is down 11% (Table E). Births delivered early term (37–38 weeks) were also down between 2011 and 2012 (Table E). The rate of births at 37 weeks of gestation declined 2% (from 8.71% in 2011 to 8.57% in 2012); births at 38 weeks were down 4% (from 17.16% to 16.39 %) (data for individual weeks not shown). Since 2006, births at 37 weeks have declined 10% and births at 38 weeks 16%; seeFigure 6

. Concurrently, the percentage of infants delivered at 39 weeks (full term) rose 2% for 2011–2012, and 17% from 2006 to 2012. Rates at 40 weeks (also full term) and 41 weeks (late term) have also risen over both time periods, but at a slower pace. The preterm birth rate for singleton births only was 9.89% in 2012, down 2% from 2011 (10.05%) and down 11% from 2006 (11.09%). Trends in gestational age among births in singleton deliveries are examined because multiple births have, on average, shorter gestations than singletons (see “Multiple births”) and can influence total trends in preterm birth. Singleton trends during 2006–2012 are similar to those summarized above for all births, thatis, declines in births at less than 39 weeks and increases at fulland late-term deliveries (Table E). Efforts to reduce nonmedically indicated cesarean deliveries and labor inductions prior to 39 weeks may be in part associated with recent national declines in deliveries prior to 39 weeks (31,33,34). Reducing the incidence of these births is of public-health importance because the risk of adverse perinatal outcome decreases with gestational age until 39–40 weeks (35,36). Preterm birth rates declined among non-Hispanic white infants (from 10.50% to 10.29%) and non-Hispanic black infants (from 16.77% to 16.53%) from 2011 to 2012; the difference in the rate for Hispanic infants (11.65% to 11.58%) was not statistically significant (Table 24). The 2012 preterm rate among non-Hispanic black infants was 10% lower than the recent peak in 2006 (18.46%) and anotherrecord low. Since 2006, preterm levels have decreased 12% for nonHispanic white infants and 5% for Hispanic infants. From 2006 to 2012 preterm birth rates declined 9%–12% among women in each 5-year age group 15–39; seeTable 25for 2012 data. In 2012 as in earlier years, preterm birth rates ranged widely by maternal age, from about 1 of 10 births to women aged 25–34, to 1 out of 5 births to mothers under age 15, and 1 of 4 births to mothers aged 45 and over. Fourteen states reported declines in preterm birth rates between 2011 and 2012; rates increased in 2 states and were unchanged in the remaining 34 states and DC; seeTable I–8for 2012 data. From 2006 to 2012, declines were observed in 44 states and DC; rates in the remaining 6 states were essentially stable. 

# Birthweight The U.S. low birthweight rate (LBW) dipped 1% for 2012, to 7.99% from 8.10%, in 2011, and 3% lower than the 2006 high (8.26%). Following increases of nearly 20% from 1990 to 2006, the percentage of LBW infants (less than 2,500 grams or 5 pounds, 8 ounces) has slowly declined (seeTables 23–25). The percentage of moderately LBW infants (1,500–2,499 grams) declined for 2011– 2012 from 6.66% to 6.57%, and is down from 6.77% in 2006.

### 10 National Vital Statistics Reports, Vol. 62, No. 9, December 30, 2013



### The rate of very low birthweight [VLBW (less than 1,500 grams)] also declined slightly from 1.44% in 2011 to 1.42% in 2012; this rate is down from 1.49% in 2006. Weight at birth is closely associated with gestational age. And as the gestational age distribution has shifted in recent years toward longer pregnancies (see “Period of gestation”), the birthweight distribution has also shifted slightly toward heavier babies. In addition to declines in infants born at less than 2,500 grams, the percentage of infants born at 2,500–2,999 grams (5 pounds, 9 ounces to 6 pounds, 9 ounces) is also down, from 18.44% to 18.28% from 2006 to 2012. Over this period, the percentage of infants delivered at 3,000 grams or greater increased from 73.30% to 73.73% (seeTable F). The lower the infant’s weight at birth, the greater the risk of poor pregnancy outcome. For 2010, 22% of infants born at less than 1,500 grams did not survive their first year, compared with just over 1% of moderately LBW infants, and 0.2% of infants born at 2,500 grams and greater (35). Even infants weighing between 2,500 and 2,999 grams are at twice the risk of early death than heavier infants (37).LBW declined among non-Hispanic white infants from 7.09% to 6.97% from 2011 to 2012 and among non-Hispanic black infants (from 13.33% to 13.18%), but it was essentially unchanged for Hispanic infants (6.96% in 2012) (Table 24). Since 2006, the LBWrate has declined 5% among non-Hispanic white, and 6% for nonHispanic black infants; rates for Hispanic infants have fluctuated only slightly. Levels of VLBW were essentially stable from 2011 to 2012 for non-Hispanic white (1.13% for 2012) and non-Hispanic black (2.93%) infants but are down for both groups from highs reported for 2005. VLBW levels for Hispanic infants have been generally stable from 2006 to 2011. The percentage of LBW infants born in singleton deliveries also declined slightly between 2011 and 2012, from 6.32% to 6.26%. The singleton LBW rate rose 10% from 1990 (5.90%) to 2006 (6.49%), but it is down 4% from the 2006 high. Overall LBW levels are influenced by changes in the rate of multiple births, which are much more likely to be LBW than infants born in singleton deliveries; see “Multiple births.’’

### During 2006–2012, declines in the percentage of LBW infants were reported for 25 states and DC—levels for the remaining states were not statistically changed. SeeTables I–9andI–10for statespecific VLBW and LBW rates for 2012. 

# Multiple births The twin birth rate was stable at 33.1 per 1,000 births for 2012, essentially unchanged from 2010 and 2011. The twinning rate (births in twin deliveries per 1,000 total births) rose steadily from 1980 to 2009 (from 18.9 to 33.2 per 1,000), but it has fluctuated only from 33.2 to 33.1 since (Tables 26and27). The number of infants born in twin deliveries was 131,024 in 2012, the lowest number in almost a decade (2003), but still nearly twice as high as the number of twins delivered in 1980 (68,339) (Table 27).Twinning rates were stable from 2011 to 2012 among nonHispanic white (36.8 per 1,000 for 2012) and non-Hispanic black (36.9) women, but declined among Hispanic women (from 23.1 to 22.6). Following rises from 1990 to 2009 (up 62% for non-Hispanic white, 42% for non-Hispanic black, and 25% for Hispanic women), twin birth rates have fluctuated fairly modestly among all three groups (Table 27). The triplet and higher-order multiple birth rate (triplet/+) declined 9% from 2011 to 2012, to 124.4 per 100,000 births, the lowest rate in 18 years (Figure 1). The triplet/+ rate (number of triplets, quadruplets, and quintuplets and other higher-order multiples per 100,000 births) rose more than 400% from 1980 to 1998, but it has since fallen by more than one-third (Tables 26and27). The number of triplet/+ births also declined 9% in 2012, to 4,919, the lowest number of triplets/+ since 1994; seeTable G. The 2012 triplet/+ number included 4,598 triplets, 276 quadruplets, and 45 quintuplets and higher-order multiple births. Recent declines in triplet/+ birth rates may be associated with guidelines from the American Society for Reproductive Medicine developed to reduce the incidence of higher-order multiple gestation pregnancies resulting from assisted reproductive technologies (ARTs) (38–40) and with improvements in ART procedures (39). Infants born in multigestation pregnancies tend to be born smaller and sooner than singletons (17) and are at higher risk of early death (35). In 2010, the latest year for which mortality data are available, twins were more than 4 times, triplets 10 times, and quadruplets were more than 20 times as likely to die in infancy (35,37). The rate of triplet/+ births declined 11% for 2011–2012 for non-Hispanic white women (from 171.0 to 152.9 per 100,000) and Hispanic women (from 78.7 to 70.1); the difference for non-Hispanic black women (108.9 to 107.8) was not statistically significant (Table 27). Differing trends in triplet/+ births are observed for 1998–2012 by race and Hispanic origin. Whereas large declines are seen among non-Hispanic white women (down 42%), rates for non-Hispanic black women have fluctuated but trended upward (23% rise), and those for Hispanic women have fluctuated fairly narrowly (75.3 in 1998 and 70.1 in 2012).

### Since 1998, when the total triplet/+ birth rate peaked, agespecific rates have declined by at least 30% for women in age groups 25 and over, with the largest decline among women aged 45 and over (from 2,326.8 per 100,000 in 1998 to 812.2 in 2012) (Table 26; 1998 data not shown). As in earlier years, triplet/+ rates ranged widely by maternal age, from 14 per 100,000 for teen mothers to more than 200 for mothers aged 35 and over in 2012. State-specific rates of multiple births vary widely; seeTable I–11. For combined years 2010–2012, more than 4.0% of all births in Connecticut, New Jersey, and Massachusetts were twins, compared with 2.6% of births in New Mexico. The highest incidence of triplet/+ births for this period was in North Dakota (194.9 per 100,000), three times as high as in New Mexico (58.4)

NOTES: Race and Hispanic origin are reported separately on birth certificates. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. Multiple-race reporting areas vary for 2003–2012; see Technical Notes. In this table, all women, including Hispanic women, are classified only according to their race; see Technical Notes.

NOTES: Race and Hispanic origin are reported separately on birth certificates. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. In this table, all women, including Hispanic women, are classified only according to their race; see Technical Notes.

1Beginning in 1997, birth rates are computed by relating births to women aged 45 and over to women aged 45–49; see Technical Notes. 2For 1970–1991, includes births to races not shown separately. For 1992 and later years, unknown race of mother is imputed; see Technical Notes. 3Based on 100% of births in selected states and on a 50% sample of births in all other states; see reference 13. 4Based on a 50% sample of births. NOTES: Race and Hispanic origin are reported separately on birth certificates. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. Multiple-race reporting areas vary for 2003–2012; see Technical Notes. In this table, all women, including Hispanic women, are classified only according to their race; see Technical Notes.

NOTES: Race and Hispanic origin are reported separately on birth certificates. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. Multiple-race reporting areas vary for 2003–2012; see Technical Notes. Persons of Hispanic origin may be of any race. In this table, Hispanic women are classified only by place of origin; non-Hispanic women are classified by race; see Technical Notes.

NOTES: Race and Hispanic origin are reported separately on birth certificates. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. Persons of Hispanic origin may be of any race. In this table, Hispanic women are classified only by place of origin; non-Hispanic women are classified by race; see Technical Notes.

NOTES: Race and Hispanic origin are reported separately on birth certificates. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. Persons of Hispanic origin may be of any race. In this table, Hispanic women are classified only by place of origin; non-Hispanic women are classified by race; see Technical Notes.

And for the Hispanic subgroups, a relative standard error for the rate of 23% or more for the ACS-based rates of 2010–2011, or fewer than 50 women for census years and 75,000 women for noncensus years in the denominator for the CPS-based rates for 1989–2009; see reference 13. 1Fertility rates computed by relating total births, regardless of age of mother, to women aged 15–44. 2Beginning in 1997, birth rates computed by relating births to women aged 45 and over to women aged 45–49; see Technical Notes. 3Excludes data for New Hampshire, which did not report Hispanic origin. 4Excludes data for New Hampshire and Oklahoma, which did not report Hispanic origin. 5Excludes data for Louisiana, New Hampshire, and Oklahoma, which did not report Hispanic origin. 6Includes Central and South American and other and unknown Hispanic. 7Includes origin not stated. 8Includes races other than white and black. NOTES: Race and Hispanic origin are reported separately on birth certificates. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. Multiple-race reporting areas vary for 2003–2012; see Technical Notes. Persons of Hispanic origin may be of any race. In this table, Hispanic women are classified only by place of origin; non-Hispanic women are classified by race; see Technical Notes.

--- Data not available. 1Includes origin not stated. 2Race and Hispanic origin are reported separately on birth certificates. Race categories are consistent with the 1977 Office of Management and Budget standards. Data for persons of Hispanic origin are included in the data for each race group according to the mother’s reported race; see Technical Notes. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. 3Includes all persons of Hispanic origin of any race. 4Birth rates computed by relating total births to unmarried mothers, regardless of age of mother, to unmarried women aged 15–44; see Technical Notes. 5Birth rates computed by relating births to unmarried women aged 40 and over to unmarried women aged 40–44. NOTES: For 49 states, the District of Columbia, and New York City marital status is reported in the birth registration process; for New York, mother’s marital status is inferred; see reference 13. Rates cannot be computed for unmarried non-Hispanic black women or for American Indian or Alaska Native women because the necessary populations are not available.

--- Data not available. 1Rates computed by relating total births to unmarried mothers, regardless of age of mother, to unmarried women aged 15–44. 2Beginning in 1997, birth rates computed by relating births to unmarried women aged 40 and over to unmarried women aged 40–44; see Technical Notes. 3Includes races other than white, black, and Asian or Pacific Islander. 4Data for states in which marital status was not reported have been inferred and included with data from the remaining states; see Technical Notes. 5Based on 100% of births in selected states and on a 50% sample of births in all other states; see reference 13. 6Births to unmarried women are estimated for the United States from data for registration areas in which marital status of mother was reported; see reference 53. 7Based on a 50% sample of births. 8Rates based on data for 48 states and the District of Columbia, which reported Hispanic origin on the birth certificate. Rates for age group 35–39 are based on births to unmarried women aged 35–44. 9Includes all persons of Hispanic origin of any race. NOTES: Race and Hispanic origin are reported separately on birth certificates. Persons of Hispanic origin may be of any race. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. Multiple-race reporting areas vary for 2003–2012; see Technical Notes. Rates cannot be computed for unmarried non-Hispanic black women or for American Indian or Alaska Native women because the necessary populations are not available.

1Rates computed by relating total births, regardless of age of father, to men aged 15–54. 2Rates computed by relating births of fathers under age 20 to men aged 15–19. 3Includes races other than white and black. 4Based on 100% of births in selected states and on a 50% sample of births in all other states; see reference 13. NOTES: Race and Hispanic origin are reported separately on birth certificates. Race categories are consistent with the 1977 Office of Management and Budget standards. Forty-one states and the District of Columbia reported multiple-race data for 2012 that were bridged to single-race categories for comparability with other states; see Technical Notes. Multiple-race reporting areas vary for 2003–2012; see Technical Notes. In this table, all men, including Hispanic men, are classified only according to their race; see Technical Notes. Age of father was not stated for 12.8% of births in 2012. See reference 13 for information on the calculation of birth rates by age of father.

# Technical Notes **Data source** Data shown in this report for 2012 are based on 100% of the birth certificates filed in all states and the District of Columbia (DC). The data are provided to the Centers for Disease Control and Prevention’s National Center for Health Statistics (NCHS) through the Vital Statistics Cooperative Program (VSCP). Information on the percentage of records with missing information for maternal and infant characteristics included in this report is shown by state inTable I. Methodological and measurement information for these characteristics is available in the “User Guide to the 2012 Natality Public Use File” (13). 

# 1989 and 2003 revisions of the U.S. Standard **Certificate of Live Birth** This report includes 2012 data on items that are collected on both the 1989 revision of the U.S. Standard Certificate of Live Birth (unrevised) and the 2003 revision (revised). The 2003 revision is described in detail elsewhere (5,6). Thirty-eight states, DC, and three territories implemented the revised birth certificate as of January 1, 2012: California, Colorado, Delaware, DC, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Washington, Wisconsin, Wyoming, Guam, the Northern Marianas, and Puerto Rico. The 38 revised states and DC represent 86% of all 2012 U.S. births. One state (Virginia) implemented the revised birth certificate in 2012, but after January 1. This report presents information on selected data items comparable between the 1989 and 2003 birth certificate revisions. Information on topics comparable between revisions but not presented in this report (e.g., day of birth, month of birth, and congenital anomalies) can be found in the Internet tables and in the “User’s Guide” public-use file for each data year (4). Information on key data items not comparable between the 1989 and 2003 birth certificate revisions—educational attainment, prenatal care, tobacco use during pregnancy, and type of cesarean and vaginal delivery— is included in the “User Guide” (13) for revised states. Beginning with the 2011 data file, data for these key noncomparable items for unrevised states are no longer included in the natality public-use data file. Recent reports and data releases present 2009, 2010, and 2011 information on items not previously available from NCHS (e.g., use of infertility therapies, WIC food, source of payment for the delivery, maternal morbidity, and breastfeeding). Information on these items as well as other items that are exclusive to the 2003 birth certificate revision (e.g., prepregnancy diabetes, gestational diabetes, external cephalic version, epidural or spinal anesthesia, and trial of labor) is presented in the “User Guide” (13). Beginning with the 2007 data file, items exclusive to the 1989 certificate revision (e.g., maternal anemia, ultrasound, and alcohol use) are not included in the natality public-use data files. 

# Age of mother Age of mother is computed in most cases from the mother’s and infant’s dates of birth as reported on the birth certificate. The mother’s age is directly reported by one state (Virginia, before April, 2012) and territory (American Samoa). From 1964 through 1996, mother’s age was edited for a range of 10–49 years. Births reported as occurring to mothers under age 10 or over age 49 are assigned the average age of mothers based on a previous year with the same race, Hispanic origin, and total birth order (total of live births and fetal deaths). Beginning in 1997, age of mother was imputed for ages 9 and under and 55 and over. This procedure was used through 2006 for births in states using the 1989 certificate. Beginning in 2003 for births occurring in revised states, a wider age range has been used— age of mother is imputed for ages 8 and under and 65 and over (mothers aged 9 are recoded as aged 10). Starting in 2007, the same procedures have been used for states using the 1989 certificate. A review and verification of unedited data for several years including 2007 showed that the vast majority of births reported as occurring to women aged 50 and over were to women aged 50–54. In this report, the final age group shown in the tables (45–49, 45–54, or 50–54) includes births to mothers up to age 64. The numbers of births to women aged 50 and over have been too small historically to compute age-specific birth rates. These births have been included with births to women aged 45–49 for computing birth rates. In 2012, age of mother was not reported on 0.01% of the records (by occurrence); for these records, age of mother was imputed according to the last record with the same race and total birth order. 

# Hispanic origin and race **Hispanic origin** Hispanic origin and race are reported separately on the birth certificate. Data are shown in most cases for five specified Hispanic groups: Mexican, Puerto Rican, Cuban, Central and South American, and other and unknown Hispanic. In tabulations of birth data by race and Hispanic origin, data for persons of Hispanic origin are not further classified by race because the vast majority of births to Hispanic women are reported as white. In tabulations of birth data by race only, data for persons of Hispanic origin are included in the data for each race group according to the mother’s reported race. In tabulations that include Hispanic origin, data for non-Hispanic persons are classified according to the race of the mother, due to substantial differences in fertility and maternal and infant health characteristics between Hispanic and non-Hispanic white women. Items asking for the Hispanic origin of the mother and the father have been included on the birth certificates of all states, DC, Virgin Islands, and Guam since 1993, on the birth certificate of Puerto Rico starting in 2005, and Northern Marianas starting in 2010 (13). American Samoa does not collect this information. The Hispanic origin question on the 2003 revision of the birth certificate asks respondents to select only one response. Occasionally, however, more than one Hispanic origin response is given, that is, a specified Hispanic group (Mexican, Puerto Rican, Cuban, or Central and South American) in combination with one or more other specified Hispanic group. When this occurs, all responses are collected.

### 62 National Vital Statistics Reports, Vol. 62, No. 9, December 30, 2013 

### In 2012, 0.4% of births in the revised-state reporting area and in Rhode Island (unrevised states that also reported more than one Hispanic origin response) were to women reporting more than one Hispanic origin. Respondents who select more than one Hispanic origin on the birth certificate are classified as “other Hispanic.” These procedures have been in place since the first revision year, 2003. The Hispanic origin question on the 1989 revision of the birth certificate also offers the opportunity to report more than one origin; however, NCHS processing guidelines for unrevised data allow only for coding the first Hispanic origin listed. Women who report more than one Hispanic origin on the 2003 revised birth certificate are included in the category “other and unknown Hispanic”; however, the American Community Survey (ACS) (41), on which the 2012 population denominators are based, randomly assigns respondents who report more than one Hispanic origin to a single origin only. [The Current Population Survey (CPS), on which the population denominators before 2010 are based, queried respondents who reported more than one Hispanic origin to obtain a single origin only (42)]. As a result, the population-based rates shown in this report for “other Hispanic” women are higher (about 6%) than if births to women reporting more than one Hispanic origin were excluded from this category. **Change in births to other and unknown Hispanic women**

— The number of births to other and unknown Hispanic women increased 3%, from 131,060 in 2011 to 135,482 in 2012. This number rose each year from 2005 through 2012. Factors that may have influenced this rise are not clear, but may include less specificity in respondent reporting of Hispanic origin (e.g., “Hispanic” in lieu of“Mexican” or “Puerto Rican”), increases in the number of multipleHispanic reporting areas, and increases in the populations of groups included in the “other Hispanic” category. The 38 revised states, DC, and Rhode Island accounted for 89% of Hispanic births in the United States in 2012. The percentage of records for which Hispanic origin of the parents was not reported in 2012 is shown by state inTable I. For additional information on the reporting of Hispanic origin, see the “User Guide” (13). 

# Single, multiple, and ‘‘bridged’’ race of mother **and father** In 1997, the Office of Management and Budget (OMB) issued Revisions to the Standards for the Classification of Federal Data on Race and Ethnicity, which revised the 1977 Race and Ethnic Standards for Federal Statistics and Administrative Reporting (14,43). These documents specify guidelines for collecting, tabulating, and presenting race and ethnicity data within the federal statistical system. The 1997 revised standards incorporated two major changes designed to reflect the changing racial and ethnic profile of the United States. First, the revision increased from four to five the minimum set of categories to be used by federal agencies for identification of race. The 1977 standards required federal agencies to report race-specific tabulations using a minimum set of four single-race categories: American Indian or Alaska Native (AIAN), Asian or Pacific Islander (API), black, and white. The five categories for race specified in the 1997 standards are: AIAN, Asian, black or African American, Native Hawaiian or Other Pacific Islander (NHOPI), and white. The revised standards called for reporting Asian persons separately from NHOPI persons. Second, the revised standards also require federal data collection programs to allow respondents to select one or more race category. Beginning with the 2000 decennial census, the U.S. Census Bureau collected race and ethnicity data in accordance with the 1997 revised standards; however, the National Vital Statistics System, which is based on data collected by the states, will not be fully compliant with the new standards until all of the states revise their birth certificates to reflect the new standards. Thus, beginning with the 2000 data year, the numerators (births) for birth rates are incompatible with the denominators (populations); see “Population denominators.” To compute rates, it is necessary to “bridge” population data for multiple-race persons to single-race categories. This has been done for birth rates by race presented in this report. Once all states revise their birth registration systems to be compliant with the 1997 OMB standards, the use of bridged populations can be discontinued. Forty-one states and DC, which represent 90% of all U.S. resident births, reported multiple-race data in 2012. Multiple-race reporting areas include: the 39 revised or partially revised states (see “1989 and 2003 revisions of the U.S. Standard Certificate of Live Birth”), DC, Guam, and Northern Marianas, which used the 2003 revision of the U.S. Standard Certificate of Live Birth; as well as Hawaii and Rhode Island, which used the 1989 revision of the U.S. Standard Certificate of Live Birth but collected multiple-race data comparable to data of the states using the revised certificate. Puerto Rico, which revised its birth certificate in 2005, reported race according to the 1989 certificate revision. Slightly more than 2% of mothers in the states reported more than one race (13). Prior to 2012, the multiple-race reporting states varied; 6 states reported more than one race in 2003, 15 states in 2004, 19 states in 2005, 23 states in 2006, 27 states in 2007, 30 states in 2008, 33 states and DC in 2009, 38 states and DC in 2010, and 40 states and DC in 2011. Data from the vital records of the remaining nine states and two territories followed the 1977 OMB standards in which only a single race is reported (43). In addition, these areas also reported the minimum set of four races as stipulated in the 1977 standards compared with the minimum of five races for the 1997 standards. To provide uniformity and comparability of data during the transition period before multiple-race data are available for all reporting areas, bridging the responses of those who reported more than one race to a single race is necessary. The bridging procedure for multiple-race mothers and fathers is based on the procedure used to bridge multiracial population estimates; see “Population denominators” (44). Multiple race is imputed to a single race (AIAN, API, black, or white) according to the combination of races, Hispanic origin, sex, and age of the mother or father indicated on the birth certificate. The imputation procedure is described in detail elsewhere (45,46). Where race of the mother is not reported, if the race of the father is known, the race of the father is assigned to the mother. When information is not available for either parent, the race of the mother is imputed according to the specific race of the mother on the preceding record with a known race of mother; see the “User Guide” (13). In 2012, race of mother was imputed for 5.8% of births (by occurrence).

### National Vital Statistics Reports, Vol. 62, No. 9, December 30, 2013 **65** 

### Beginning with the 1989 data year, NCHS started tabulating its birth data primarily by race of mother. In 1988 and prior years, births were tabulated by race of child, which was determined from the race of the parents as entered on the birth certificate (13). Trend data by race shown in this report are by race of mother for all years beginning with the 1980 data year. Text references to white births and white mothers or to black births and black mothers are used interchangeably for ease in writing.

# Birthweight Birthweight is reported in some areas in pounds and ounces rather than in grams; however, the metric system has been used in tabulating and presenting the statistics to facilitate comparison with data published by other groups. Equivalents of the gram weights in terms of pounds and ounces are presented below: Less than 500 grams = 1 lb. 1 oz. or less 500–999 grams = 1 lb. 2 oz.–2 lb. 3 oz. 1,000–1,499 grams = 2 lb. 4 oz.–3 lb. 4 oz. 1,500–1,999 grams = 3 lb. 5 oz.–4 lb. 6 oz. 2,000–2,499 grams = 4 lb. 7 oz.–5 lb. 8 oz. 2,500–2,999 grams = 5 lb. 9 oz.–6 lb. 9 oz. 3,000–3,499 grams = 6 lb. 10 oz.–7 lb. 11 oz. 3,500–3,999 grams = 7 lb. 12 oz.–8 lb. 13 oz. 4,000–4,499 grams = 8 lb. 14 oz.–9 lb. 14 oz. 4,500–4,999 grams = 9 lb. 15 oz.–11 lb. 0 oz. 5,000 grams or more = 11 lb. 1 oz. or more

# Population denominators **2012 population estimates** The birth and fertility rates for 2012 shown inTables A–C,1, 3–5,7–9,12–14, and17are based on populations estimated from the 2010 census as of July 1, 2012. These populations are shown inTable II. The population estimates have been provided by the U.S. Census Bureau (47), and they are based on the 2010 census counts by age, sex, and race, which have been modified for consistency with 1977 OMB race categories and historical categories for birth data. The modification procedures are described in detail elsewhere (44). The birth and fertility rates by state shown inTable 12are based on state-level population counts, which are based on the 2010 census provided by the U.S. Census Bureau (47). Birth and fertility rates shown inTable 12for the territories except Puerto Rico are based on population estimates provided by the U.S. Census Bureau’s International Data Base (48). [Rates for Puerto Rico are based on population estimates from the 2010 census as of July 1, 2012, and are provided by the U.S. Census Bureau (49)]. Rates by state and territory shown in this report may differ from rates computed on the basis of other population estimates; rates for smaller population subgroups, such as those for teen mothers, may be particularly affected by differences in population estimates. Birth and fertility rates by month shown inTable I–2are based on monthly population estimates for 2012, which are also based on 2010 census estimates. Rates for unmarried women shown inTables 15and 16are based on distributions of the population by marital status averaged over a 3-year period for 2011–2013. These distributions were reported by the U.S. Census Bureau in the March CPS for each year (50–52), and have been adjusted to July 1, 2012 (2010 census) population levels (47) by NCHS’ Division of Vital Statistics (DVS) (53). 

## Population estimates for the specific Hispanic groups Beginning in 2011, birth and fertility rates for the Hispanic population groups (Mexican, Puerto Rican, Cuban, Central and South American, and other Hispanic populations) shown inTables 5,7,8, and14are based on population estimates derived from the 1-year ACS (54), and are adjusted to the U.S. resident population control totals by the U.S. Census Bureau. Rates for the specific Hispanic population groups prior to 2010 shown in this report are based on population estimates derived from CPS and adjusted to the U.S. resident population control totals by the U.S. Census Bureau or byDVS (see “Revised population estimates”). The switch to the ACSbased rates was made because ACS estimates are more statistically reliable and represent the entire U.S. population. ACS estimates are based on an approximate 3 million annual sample of the U.S. population, including all households (civilian and military) and the institutionalized population (persons living in group quarters) (55). CPS estimates are based on an approximate 200,000 sample of the civilian noninstitutionalized U.S. population (56). The larger ACS sample makes it possible to show rates in this report in more detail than in previous years, especially for Cuban and Puerto Rican women. The 2012 population estimates are derived from the 2012 1-year ACS and are adjusted according to the (2010-based) postcensal estimates of the total population for July 1, 2012. The 2010 and birth and fertility rates for the specific Hispanic population groups were also revised using ACS-based population estimates. Total population estimates for Hispanic groups in 2012 are presented inTable II. More information about the populations for Hispanic groups is presented elsewhere (13). 

## Revised population estimates Birth and fertility rates by race for 2001–2009 shown in this report have been modified according to revised intercensal population estimates based on the 2000 and 2010 censuses, to provide more accurate rates for the period (57). A full series of revised rates by state, by live-birth order, and by age for 2001–2009 based on these revised population estimates is available upon request. These revised rates may differ from the intercensal rates published in

NOTES: Population count estimates are based on the 2010 census; see Technical Notes. Race categories are consistent with the 1977 Office of Management and Budget standards. Multiple-race population estimates were bridged to the single-race categories for comparability with the birth data; see Technical Notes. Population estimates for Mexican, Puerto Rican, Cuban, Central and Other Hispanic, which includes Central and South American and other and unknown Hispanic, are based on the American Community Survey adjusted to resident population control totals (the 2010-based population estimates for the United States for July 1, 2012). Population estimates for Hispanic total are based on the 2010 census, as of July 1, 2012. Population estimates by specified Hispanic origin in this table may not add to population estimates for total Hispanic. Standard errors are shown in parentheses below each population estimate.

### National Vital Statistics Reports, Vol. 62, No. 9, December 30, 2013 **67** 

### “Births: Final Data for 2010,” the original rates published in “Births: Final Data for 2009,” and earlier reports that were based on 2000 postcensal population estimates (58,59). Differences in the revised rates compared with intercensal rates are slight, and vary by age and race and Hispanic origin population group. The populations by race used in this report were produced under a collaborative arrangement with the U.S. Census Bureau and are based on the 2010 census counts. Reflecting the new OMB guidelines issued in 1997, the 2010 census (and 2000 census) included an option for persons to report more than one race as appropriate for themselves and household members (14). In addition, the 1997 OMB guidelines called for the reporting of Asian persons separately from NHOPI persons. In the 1977 OMB guidelines, data for API persons were collected as a single group (43). For the nonmultiple-race reporting areas (nine states, American Samoa, U.S. Virgin Islands, and Puerto Rico), birth certificates currently report only one race for each parent in the categories specified in the 1977 OMB guidelines (see “Hispanic origin and race”). In addition, birth certificate data for the states using the 1989 birth certificate revision do not report Asian persons separately from NHOPI persons. Thus, birth certificate data by race (the numerators for birth and fertility rates) currently are incompatible with the population data collected in the 2010 census (the denominators for the rates). To produce birth and fertility rates for 1991 through 2012, the reported population data for multiple-race persons were bridged to single-race categories. In addition, the 2010 (and 2000) census counts were modified to be consistent with the 1977 OMB race categories, that is, to report the data for Asian and NHOPI persons as the combined category of API (47). The procedures used to produce the bridged populations are described in a separate publication (44). Revised intercensal population estimates for the specified Hispanic groups from 2001 through 2009 used in this report are not currently available from the U.S. Census Bureau, and rates have been recalculated using intercensal population estimates prepared by DVS. The population estimates were produced by applying proportions derived from the 2000-based population estimates (according to year, sex, and age for the specified Hispanic population groups) to the 2010-based population of Hispanic females by age group, and by adjusting the sum of the population estimates to be consistent with the total population of Hispanic females by age (2010 based). These population estimates are available upon request from NCHS (Births@ cdc.gov). The population data used to compile birth and fertility rates by race and ethnicity shown in this report are based on special estimation procedures and are not actual counts. This is the case even for the 2000 and 2010 populations that are based on the 2000 and 2010 censuses. As a result, the estimation procedures used to develop these populations may contain some errors. Smaller populations, like AIAN, are likely to be affected much more than larger populations by potential measurement error (44). Although the nature and magnitude of error is unknown, the potential for error should be considered when evaluating trends and differentials. As more accurate information becomes available, further revisions to the estimates may be necessary. For additional information and discussion on the population denominators, see the “User Guide” (13).
