Recent Decline in Births in the United States, 2007–2009

paul d. sutton, ph.d.; Brady e. hamilton, ph.d.; and t.J. mathews, m.s. 

The number of births in the United States reached an all-time high of 

4,316,233 in 2007, but that number has since fallen (1–3). From 2007 through 

2009, births fell 4 percent to 4,131,019; and the provisional count of births 

through June 2010 indicated continued declines (3). Fertility rates—which 

relate the number of births to women aged 15–44 (i.e., the childbearing 

years)—also fell during this time frame.

This report takes a more detailed look at the decline in births from 2007 

through 2009 by mother’s age, race and ethnicity, birth order, and state. The 

analysis is based on a comparison of 2007 final and 2009 preliminary birth 

data from the National Vital Statistics System (NVSS), and are the most 

current detailed birth data available.

Keywords: fertility decline • birth rates • race and Hispanic origin • state rates

Fertility rates fell more rapidly from 2007 through 2009 than 

for any 2-year period in more than 30 years.

• From 2007 through 2009, the fertility rate fell 4 percent from 69.5 to 

66.7 births per 1,000 women aged 15–44.

Key findings

• From 2007 through 2009, 

birth rates for women aged 

15–44 (fertility rates) fell 

for most states and nearly all 

major population subgroups.

• Birth rates declined for all 

women under age 40 with 

some of the largest decreases 

for women in their peak 

childbearing years.

• Fertility rates dropped for 

all major racial and Hispanic 

groups with the largest 

declines among Hispanic 

women.

• Birth rates by live-birth 

order also fell with the largest 

declines for third-order births 

and progressively smaller 

declines for second- and firstorder births.

• Fertility rates decreased 

or were unchanged in every 

state and the District of 

Columbia with the largest 

declines among western and 

southeastern states.

• The fertility decline from 2007 through 2009 is relatively small in a historical context 

compared with the declines in the early 20th century and in the 1960s and early 1970s 

(Figure 1). The most recent extended period of fertility decline was in the 1990s when the 

fertility rate fell 10 percent from 1990 through 1997 to an all-time low of 63.6. With the 

exception of a small decline from 2000 through 2002, the fertility rate between 1997 and 

2007 increased.

• It is not yet known if fertility rates will experience another extended decline, but provisional 

data indicate a continuing decline in the rate through June 2010 (3).

Birth rates declined for mothers under age 40 but rose for mothers aged 40 

and over.

• From 2007 through 2009, birth rates fell for all women under age 40 (Figure 2 and Table). 

• Birth rates fell 9 percent for women aged 20–24 (to 96.3 births per 1,000 women, the lowest 

rate ever recorded for this age group), and 6 percent for women aged 25–29. Rates also 

declined for women in their 30s (2 percent each).

•	 The birth rate for teenage women (aged 15–19) also declined, falling 8 percent from 2007 

through 2009 (to 39.1 births per 1,000 women, the lowest rate ever recorded for this age 

group) (4).

•	 Birth rates rose for women in their 40s, the only age group to do so. The rate rose 6 percent 

for women aged 40–44. Births to women in this age group, however, represented only 3 

percent of total births in 2009.

Fertility rates for Hispanic women fell more than for any other population 

group.

•	 From 2007 through 2009, fertility rates dropped for all racial and ethnic groups (Figure 3

and Table).

•	 The fertility rate for Hispanic women fell 9 percent from 2007 to 2009, to 93.3 per 1,000 

women, the lowest rate for Hispanic women since 1999 and the largest decline of any group.

•	 The fertility rate for non-Hispanic white women (accounting for over one-half of all births) 

declined 3 percent.

•	 The fertility rate also fell 3 percent for American Indian or Alaska Native women and 4 

percent	for	non-Hispanic	black	and	Asian	or	Pacific	Islander	women.

Birth rates declined for all live-birth orders.

• From 2007 through 2009, birth rates declined for all live-birth orders (Figure 4 and Table).

• The first birth rate for women aged 15–44 fell 3 percent and the second-order birth rate 

fell 5 percent in 2009. First- and second-order births accounted for nearly three-quarters of 

births in 2009.

• The third- and fourth- or higher-order birth rates also declined in 2009 (down 6 percent and 

1 percent).

Fertility rates fell most rapidly in the western and southeastern 

United States.

• State-specific fertility rates in 2009 were significantly lower than they had been in 2007 for 

42 states (Figure 5). Fertility rates in the other eight states and the District of Columbia were 

essentially unchanged. 

• Fertility rates fell in most states, but the size of the decline varied widely from 1 percent in 

New York and Oklahoma to 10 percent or more in Arizona and Nevada. 

• Declines were largest in the western and southeastern United States.

Summary

The fertility rate in the United States fell 4 percent from 2007 through 2009, to 66.7 births per 

1,000 women aged 15–44. The 2-year decline was notable, but not truly of historic proportions 

when compared with the large, extended fertility declines in the early 20th century and in the 

1960s and early 1970s. Nevertheless, the fertility rate decline from 2007 through 2009 was 

broad-based, both demographically and geographically. Rates fell for all women under age 40, 

for all major racial and ethnic groups, for all birth orders, and in most states (42 total). However, 

substantial differences in the size of the declines among groups were present.

Some researchers have linked the recent fertility decline to the economic recession (5), but it is 

not possible with birth data alone to identify the factors shaping the fertility rate decline.

Definitions

Fertility rate: The number of live births per 1,000 women aged 15–44 in specified group.

Birth rate by age of mother: The number of live births per 1,000 women in specified age group.

Data sources and methods

This report contains data from the NVSS Natality Data Files. The vital statistics natality files 

include information for all births occurring in the United States. The natality files include 

information on a wide range of maternal and infant demographic and health characteristics for 

babies born in the United States. The files are available from http://www.cdc.gov/nchs/data_

access/Vitalstatsonline.htm. Data may also be accessed from the interactive data tool, VitalStats, 

available from http://www.cdc.gov/nchs/VitalStats.htm.

For information and discussion on the computation of population-based rates and on significance 

testing for natality data, see “Births: Preliminary Data for 2005” (6) and “User Guide to the 2008 

Natality Public Use File” (7).

Birth data for 2009 are preliminary (2). Information on the 2009 data is available elsewhere (2). 

Population data for computing fertility rates were provided by the U.S. Census Bureau. Rates by 

state may differ from rates computed on the basis of other population estimates (8).
