More Deaths Than Births: Subnational Natural Decrease in Europe and the United States

This article examines the prevalence and dynamics of natural decrease in the subnational populations of Europe and the United States. Natural decrease results from interactions between fertility, mortality, and migration over a protracted period. We document the greater incidence and degree of natural decrease in Europe. In the first decade of the twenty‐first century, natural decrease occurred in 58 percent of European NUTS 3 areas (“counties”) compared to only 28 percent of the US counties. Three critical demographic variables (proportion over 65, child‐women ratio, and proportion of women of childbearing age) each exert a significant and distinct impact on the likelihood of natural decrease. Our spatial regression models reflect remarkable consistency in the influence of each of these variables in Europe and in the US, demonstrating the similarity in the demographic processes that produce natural decrease.     

Recent Trends in Coverage of the Mexican-Born Population of the United States: Results From Applying Multiple Methods Across Time

The accuracy of counts of U.S. racial/ethnic and immigrant groups depends on the coverage of the foreign-born in official data. Because Mexicans constitute by far the largest single national-origin group among the foreign-born in the United States, we compile new evidence about the coverage of the Mexican-born population in the 2000 census and 2001–2010 American Community Survey (ACS) using three techniques: a death registration, a birth registration, and a net migration method. For the late 1990s and first half of the 2000–2010 decade, results indicate that coverage error was somewhat higher than currently assumed but had substantially declined by the latter half of the 2000–2010 decade. Additionally, we find evidence that U.S. census and ACS data miss substantial numbers of children of Mexican immigrants, as well as people who are most likely to be unauthorized: namely, working-aged Mexican immigrants (ages 15–64), especially males. The findings highlight the heterogeneity of the Mexican foreign-born population and the ways in which migration dynamics may affect population coverage.     

Recent developments in longitudinal studies of aging in the United States

We review recent developments in longitudinal studies of aging, focusing on the Wisconsin Longitudinal Study (WLS) and the Health and Retirement Study (HRS). Both studies are part of a trend toward biosocial surveys in which biological measurement is joined with traditional survey techniques, and a related trend toward greater harmonization across studies. Both studies have collected DNA samples and are working toward genotyping that would allow broadly based association studies. Increased attention to psychological measurement of personality and of cognitive ability using adaptive testing structures has also been shared across the studies. The HRS has expanded its economic measurement to longitudinal studies of consumption and to broader-based measurement of pension and Social Security wealth. It has added biomarkers of cardiovascular risk. The WLS has developed an integrated approach to the study of death and bereavement and an innovative use of high school yearbook photographs to capture information about health in early life of its participants.     

Sex of Previous Children and Intentions for Further Births in the United States, 1965-1976

The research reported herein, using samples of women interviewed in the 1965 and 1970 National Fertility Studies and the 1976 National Survey of Family Growth, shows that the sex of women’s previous children has an effect on their subsequent fertility intentions which differs at each parity. The persistence of that effect among women with two children in particular argues strongly for including sex of previous children as an independent variable in models of fertility intentions, since the decline in family size norms makes factors which affect the decision to have (or not have) a third child increasingly important.     

Explaining Disability Trends in the United States, 1963–2015

The National Health Interview Survey is the world's longest survey time series of health data. In spite of the availability of such a long time series, previous studies did not attempt to explain long‐term trends in disability, because the design of the question in the survey has changed over time. To control for changes in the design of the question, I added two variables indicating major changes in the design to the analysis. My results show that the decline in mortality from cardiovascular disease is associated with the rise in disability in the 1970s, whereas better education is associated with the long‐term decline in disability that started in the 1980s. Combined, the two variables are able to account for all major trends in disability at age 50–84 from 1963 to 2015, leaving limited room for other explanations. The statistical model predicts that the trend in falling disability rates will end as the rise in educational levels draws to a halt.     

Spatial and Temporal Trends in Multidimensional Poverty in the United States over the Last Decade

This paper undertakes a comprehensive analysis of multidimensional poverty in the United States over the last decade. It provides estimates of multidimensional poverty over more than a decade, from 2008 to 2019, which covers the Great Recession and the recovery following the recession when major policy changes such as the Affordable Care Act were implemented. For the first time, spatial trends in estimates of multidimensional poverty are also provided. We measure annual poverty levels in 4 regions, 50 states and examine the relation between multidimensional poverty and neighborhood characteristics. We find that on average, 13 percent of the United States population was multidimensional poor. Poverty rates were high in the South and the West and among young adults, immigrants and Hispanics. Alternative indices of multidimensional poverty show consistent trends; multidimensional poverty in the United States rose between 2008 and 2010 and then gradually declined. However, more than a quarter of individuals with incomes above the poverty threshold remained multidimensional poor. This underscores the fact that income does not always capture deprivation experienced by individuals. Policies geared towards affordable housing, health insurance and higher education will help reduce multidimensional poverty in the United States.

     

Trends in health of older adults in the United States: Past,present, future

The decline in late-life disability prevalence in the United States was one of the most important developments in the well-being of older Americans in the 1980s and 1990s, but there is no guarantee that it will continue into the future. We review the past literature on trends in disability and other health indicators and then estimate the most recent trends in biomarkers and limitations for both the population aged 65 and older and those aged 40 to 64, the future elderly. We then investigate the extent to which trends in education, smoking, and obesity can account for recent trends in limitations and discuss how these three factors might influence future prospects for late-life health. We find that improvements in the health of the older population generally have continued into the first decade of the twenty-first century. The recent increase in the proportion of the younger population needing help with activities of daily living is concerning, as is the doubling of obesity in the last few decades. However, the increase in obesity has recently paused, and favorable trends in education and smoking are encouraging.

Long‐Term Trends in Life Expectancy and Active Life Expectancy in the United States

Changes in life expectancy and in active life expectancy may have effects on the fiscal integrity of both the Social Security and Medicare programs. Analysis of the fiscal stability of these programs shows that the most serious problem may be the growth of Medicare expenditures projected to surpass, in about 2024, Social Security costs. This is aggravated by the associated rapid growth of the Medicaid program. To understand how the growth of Medicare, Medicaid, and Social Security might be correlated we present estimates of changes in life expectancy and active life expectancy from 1935 to 1999 and then project those values to 2080. How the correlation of life expectancy and active life expectancy changes over time, and by age, may provide insights into how increased health care expenditures, if effective in changing health in the elderly, could modify the age structure of the labor force and the availability of human capital.     

Trends in Late-Life Activity Limitations in the United States: An Update From Five National Surveys

This article updates trends from five national U.S. surveys to determine whether the prevalence of activity limitations among the older population continued to decline in the first decade of the twenty-first century. Findings across studies suggest that personal care and domestic activity limitations may have continued to decline for those ages 85 and older from 2000 to 2008, but generally were flat since 2000 for those ages 65–84. Modest increases were observed for the 55- to 64-year-old group approaching late life, although prevalence remained low for this age group. Inclusion of the institutional population is important for assessing trends among those ages 85 and older in particular.     

Trends in the Economic Independence of Young Adults in the United States: 1973–2007

One of the major milestones of adulthood is achieving economic independence. Without sufficient income, young people have difficulty leaving their childhood home, establishing a union, or having children—or they do so at great peril. Using the National Longitudinal Survey, this article compares the employment and economic circumstances of young adults aged 22–30 in 1973, 1987, and 2007, and their possible determinants. The results show that achieving economic independence is more difficult now than it was in the late 1980s and especially in the 1970s, even for the older age groups (age 27–28). The deterioration is more evident among men. From the 1970s there has been convergence in the trajectories for the achievement of economic self‐sufficiency between men and women, suggesting that the increase in gender parity, especially in education and labor market outcomes, is making their opportunities to be employed and to earn good wages more similar. This convergence also suggests that union formation increasingly may depend on a capacity to combine men's and women's wages.     

Intergenerational Transmission of Age at First Birth in the United States: Evidence from Multiple Surveys

It is well established that the timing of childbearing is transmitted from parents to children in the United States. However, little is known about how the intergenerational link has changed over time and under structural and ideological transformations associated with fertility behaviors. This study first considers changes across two birth cohorts from the National Longitudinal Survey of Youth (NLSY) in the extent to which parents’ age at first birth is transmitted to their children. The first cohort includes individuals born during the late 1950s through the early 1960s (NLSY79), while the second includes individuals born in the early 1980s (NLSY97). Results from discrete-time event history analyses indicate that the intergenerational transmission of age at first birth significantly increased for both daughters and sons. These results were confirmed by analyses of data from three cycles of the National Survey of Family Growth spanning the same time period. Over this period, age at first childbirth became increasingly younger for children born to teenage mothers and increasingly older for those born to mothers who began parenthood after age 25. These patterns have important implications for the reproductive polarization hypothesis.     

Changing patterns of migration between metropolitan and nonmetropolitan areas in the United States: Recent evidence

Data from the 1975 Current Population Survey confirm that, during 1970–1975, there was a reversal of the traditional net migration stream between metropolitan and nonmetropolitan areas in the United States. During this period, there was net in-migration of 1,600,000 persons to nonmetropolitan areas, in contrast to net out-migration of 350,000 persons from these areas in 1965–1970. Reversal was caused by a 12 percent decrease in the number of nonmetropolitan out-migrants and a 23 percent increase in the number of SMSA residents moving to nonmetropolitan territory over 1965–1970 levels. While some changes in the size of migration streams were due to changes in age structures and population bases in metropolitan and nonmetropolitan areas, they were caused primarily by real shifts in outmigration propensities at practically all ages in both areas.     

Delayed childbearing in the United States

This article analyzes the phenomenon of delayed childbearing in the United States. It begins by exploring problems associated with the definition and measurement of delayed childbearing. Existing empirical evidence of the phenomenon is reviewed and some new evidence is presented. A general theoretical framework for analyzing delayed childbearing is outlined and discussed in relation to existing theories. The article also provides a critical substantive and methodological review of evidence on the correlates and implications of delayed childbearing. Finally, public and private policy-related aspects of delayed childbearing are considered.     

Homicide trends in the United States

Unlike most other causes of death, homicide has been increasing in the United States, especially since the mid-1960s. Its impact is greatest among nonwhite men. The elimination of homicide would add approximately one and one-half years to their life span. This analysis examines trends and differentials using vital statistics data about homicide victims. A decomposition of components of change reveals that almost all of the rise in homicide mortality among nonwhites and a substantial fraction of the rise among whites results from the increasing use of firearms to kill people.

Marriage (Still) Matters: The Contribution of Demographic Change to Trends in Childlessness in the United States

Childlessness in the United States nearly doubled between 1980 and 2000. Other dramatic changes in the U.S. population also took place over this period—notably, women’s average educational attainment increased, and the proportion marrying declined—but the impact of these changes on childlessness has not been formally examined. In this article, I use data from the Current Population Survey Fertility Supplements (1995, 1998, 2004, 2008) and logistic regression and regression-based decomposition techniques to assess the contribution of changes in educational attainment, marriage behavior, and racial/ethnic composition on population levels of childlessness in the United States. Results show that increases in the proportion of women unmarried by age 40 contributed most to the increase in childlessness in the late twentieth century, although these increases were offset somewhat by increased childbearing among unmarried women. The rising proportion of women with a college degree also explained a substantial amount of the increase in childless women.     

Forecasts of population in the United States

Nondrinker Mortality Risk in the United States

The literature has shown that people who do not drink alcohol are at greater risk for death than light to moderate drinkers, yet the reasons for this remain largely unexplained. We examine whether variation in people’s reasons for nondrinking explains the increased mortality. Our data come from the 1988–2006 National Health Interview Survey Linked Mortality File (N = 41,076 individuals age 21 and above, of whom 10,421 died over the follow-up period). The results indicate that nondrinkers include several different groups that have unique mortality risks. Among abstainers and light drinkers the risk of mortality is the same as light drinkers for a subgroup who report that they do not drink because of their family upbringing, and moral/religious reasons. In contrast, the risk of mortality is higher than light drinkers for former drinkers who cite health problems or who report problematic drinking behaviors. Our findings address a notable gap in the literature and may inform social policies to reduce or prevent alcohol abuse, increase health, and lengthen life.     

Multidimensional Racial Inequality in the United States

This paper measures racial inequalities in the US using a multidimensional ‘wellbeing’ approach that simultaneously considers the distributions of income, health and education. The primary objective is to examine trends in US wellbeing inequality with an emphasis on changes in racial composition. Data is taken from 1990 to 2007 and we observe increases in income inequality, a decline in education inequality and unchanged health inequality over the period. Taken together, these results show a slight increase in the dispersion in multidimensional wellbeing. Stratifying by racial groups shows that this increase is due to widening intra-racial inequalities while inter-racial differences remained unchanged. The method is also used to evaluate wellbeing across groups and we estimate black wellbeing to average around 76 % of whites, while persons from other races average approximately 93 %. Some other changes in composition occur through time and the results are shown to be robust to a number of changes in parametric weightings.
