The impact of family policies on fertility in industrialized countries: a review of the literature

Abstract: This paper examines the theoretical propositions and empirical evidence linking policies and fertility. More specifically, the analysis presented in this paper draws attention to the complex mechanisms that theoretically link policies and demographic outcomes: mechanisms that involve imperfect information and decisions that are rationally bound by very specific circumstances. As to the empirical evidence, studies provide mixed conclusions as to the effect of policies on fertility. While a small positive effect of policies on fertility is found in numerous studies, no statistically significant effect is found in others. Moreover, some studies suggest that the effect of policies tends to be on the timing of births rather than on completed fertility.

Births: final data for 2007.

Abstract: OBJECTIVES This report presents 2007 data on U.S. births according to a wide variety of characteristics; preliminary 2008 data are also referenced on key measures where available. Final 2007 data are presented for maternal demographic characteristics including age, live-birth order, race and Hispanic origin, marital status, and educational attainment; maternal lifestyle and health characteristics (medical risk factors, weight gain, and tobacco use); medical care utilization by pregnant women (prenatal care, obstetric procedures, characteristics of labor and/or delivery, attendant at birth, and method of delivery); and infant characteristics (period of gestation, birthweight, Apgar score, congenital anomalies, and multiple births). Birth and fertility rates by age, live-birth order, race and Hispanic origin, and marital status also are presented. Selected data by mother's state of residence are shown, as well as data on month and day of birth, sex ratio, and age of father. Trends in fertility patterns and maternal and infant characteristics are described and interpreted. METHODS Descriptive tabulations are presented of data reported on the birth certificates of the 4.3 million births that occurred in 2007. Preliminary 2008 data are based on 99.9 percent of births occurring in 2008. Denominators for population-based rates are postcensal estimates derived from the U.S. 2000 census. RESULTS A total of 4,316,233 births were registered in the United States in 2007, the largest number of births ever reported. The general fertility rate increased 1 percent to 69.5 per 1,000. Birth rates increased for women in nearly all age groups. The rate for teenagers rose 1 percent for the year and is up 5 percent from 2005. The total fertility rate increased 1 percent to 2,122.0 births per 1,000 women. Preliminary data for 2008, however, suggest a decline in the number and rate of births overall, and for most age groups under age 40 years. All measures of unmarried childbearing reached record levels in 2007. The cesarean delivery rate rose to another all-time high--31.8 percent. Preterm and low birthweight rates declined slightly, and twin and triplet and higher-order multiple birth rates were essentially unchanged. Preliminary findings for 2008 suggest that these trends continued for cesarean delivery, unmarried childbearing, and preterm births.

Adolescent pregnancy and childbearing: levels and trends in developed countries.

Abstract: Context Adolescent pregnancy occurs in all societies, but the level of teenage pregnancy and childbearing varies from country to country. A cross-country analysis of birth and abortion measures is valuable for understanding trends, for identifying countries that are exceptional and for seeing where further in-depth studies are needed to understand observed patterns. Methods Birth, abortion and population data were obtained from various sources, such as national vital statistics reports, official statistics, published national and international sources, and government statistical offices. Trend data on adolescent birthrates were compiled for 46 countries over the period 1970-1995. Abortion rates for a recent year were available for 33 of the 46 countries, and data on trends in abortion rates could be gathered for 25 of the 46 countries. Results The level of adolescent pregnancy varies by a factor of almost 10 across the developed countries, from a very low rate in the Netherlands (12 pregnancies per 1,000 adolescents per year) to an extremely high rate in the Russian Federation (more than 100 per 1,000). Japan and most western European countries have very low or low pregnancy rates (under 40 per 1,000); moderate rates (40-69 per 1,000) occur in Australia, Canada, New Zealand and a number of European countries. A group of five countries--Belarus, Bulgaria, Romania, the Russian Federation and the United States--have pregnancy rates of 70 or more per 1,000. The adolescent birthrate has declined in the majority of industrialized countries over the past 25 years, and in some cases has been more than halved. Similarly, pregnancy rates in 12 of the 18 countries with accurate abortion reporting showed declines. Decreases in the adolescent abortion rate, however, were less prevalent. Conclusions The trend toward lower adolescent birthrates and pregnancy rates over the past 25 years is widespread and is occurring across the industrialized world, suggesting that the reasons for this general trend are broader than factors limited to any one country: increased importance of education, increased motivation of young people to achieve higher levels of education and training, and greater centrality of goals other than motherhood and family formation for young women.

Mass education as a determinant of the timing of fertility decline.

Abstract: This article proposes mechanisms through which mass education produces declines in fertility and reviews the evidence both in the 19th century demographic transition in the west and in contemporary developing countries for such a relationship. It is argued that the primary determinant of the timing of the onset of the fertility transition is the effect of mass education on the family economy. The direction of the wealth flow between generations changes with the introduction of mass education at least partly because the relationships between members of the family are transformed as the morality governing those relationships changes.
