Population Research and Policy Review

Birth weight is a key human biological characteristic as a measure of prenatal development and a variable related to later quality of life. Studies have firmly established that a stressful situation in utero adversely affects newborns' birth weight. Using birth statistics provided by Statistics Korea, this study examined how universal cash transfer during the COVID-19 crisis affected newborns' birth weight in South Korea. Given that the normal gestation period is nearly 10 months, we chose newborns without a self-selection issue by utilizing information on birthdate and total pregnancy period from the dataset, subsequently applying difference-in-differences estimation...

The 2008 economic crisis, also called the Great Recession, produced only a moderate rise in unemployment in Italy, but the consequences for public debt management were far more serious. Italy makes for a good case study for evaluating the effect on life expectancy at birth of the cost containment program in the health care system, implemented after the crisis began. To this end we employed the Artificial Control method using the data from the Human Mortality Database to assess the causal effect of the 2008 economic crisis on the subsequent evolution of life expectancy at birth (until 2019, before the onset of the COVID-19 pandemic)...

In many OECD countries, women are underrepresented in high status, high paying occupations and overrepresented in lower status work. One reason for this inequity is the "motherhood penalty," where women with children face more roadblocks in hiring and promotions than women without children or men with children. This research focuses on divergent occupational outcomes between men and women with children and analyzes whether parental gender gaps in occupational status are more extreme for immigrant populations...

The age distribution of a population is important for understanding the demand and provision of labor and services, and as a denominator for calculating key age-specific rates such as fertility and mortality. In the US, the most important source of information on age distributions is the decennial census, but a new disclosure avoidance system (DAS) based on differential privacy will inject noise into the data, potentially compromising its utility for small areas and minority populations. In this paper, we explore the question whether there are statistical methods that can be applied to noisy age distributions to enhance the research uses of census data without compromising privacy...

Influenza vaccination is a critical preventive healthcare behavior designed to prevent spread of seasonal flu. This paper contributes to existing scholarship by applying an intersectional perspective to examine how influenza vaccination differs across specific intersections of racial/ethnic and sexual identity. Drawing on aggregated state-level data from Behavioral Risk Factor Surveillance System (BRFSS) from 2011 to 2020, I examine how flu vaccination differs across 18 racial/ethnic-by-sexual orientation groups ( N  = 1,986,432)...

Inequities in access to contraception based on ability to pay can interfere with individuals' reproductive autonomy. This study examines the impact of a 2017 state-level policy in Iowa restricting Medicaid coverage at abortion-providing health care centers on patients' access to contraceptive care and subsequent contraceptive use. We draw on a unique panel dataset of individuals who originally sought care at a publicly supported family planning site in Iowa in 2018-2019 and then participated in subsequent follow-up surveys every 6 months for 2 years to examine an effect of access to care on contraceptive use...

International migration is an important source of population change and economic development for Pacific Island countries. Migration from the Pacific Island region contributes to labour recruitment in countries like Australia, New Zealand and the United States. However, there are substantial gaps in the understanding of overall migration patterns in this region, impeding the development of relevant policies. In the absence of good migration statistics, we propose and present an alternative approach to examining the levels of migration in the Pacific Island region using model-based estimates...

It is important to assess the long-term consequences of the COVID-19 pandemic for gender equality, but we know little about US parents' domestic arrangements beyond the early days of the pandemic or how simultaneous changes in employment, earnings, telework, gender ideologies, and care supports may have altered domestic arrangements. This study assesses changes in parents' domestic labor during the first year of the pandemic using fixed - effects regression on data from a longitudinal panel of 700 different-sex partnered US parents collected at three time points: March, April, and November 2020...

Considerable research in western, low-fertility contexts has examined minority-vs.-majority fertility differentials, typically focusing on minority groups' cultural idiosyncrasies and on socioeconomic disadvantages associated with minority status. However, the formation and functioning of ethnic complexities outside the western world often diverge from the standard western model and so may their impact on fertility preferences, behavior, and outcomes. We expand on the previous research by analyzing ethnic variation in completed and desired fertility in the multiethnic transitional setting of Kyrgyzstan, where ethnic groups and their ethnolinguistic subparts are characterized by both different stages of the demographic transition and different positioning in the socioeconomic and political hierarchies...

This study aims to fill two interrelated knowledge gaps in the extant literature on the association between perceived discrimination and health. First, potential selection bias associated with pre-existing health conditions has rarely been rigorously tested in empirical studies. Second, whether there is a reciprocal relationship between perceived discrimination and health has been underexplored. Using longitudinal data from the Americans' Changing Lives data, waves 3 to 5 ( N= 1,058), we test the reciprocity between perceived discrimination and health with a formal mediation analysis technique...

Due to increasing heterogeneity in if, when, and under what conditions women have children, the timing, spacing, and other demographic aspects of childbearing have drastically changed in the US over the past century. Existing science tends to examine demographic aspects of childbearing separately, creating an incomplete understanding of how childbearing patterns are distributed at the population level. In this research brief, we develop the concept of childbearing biographies to emphasize that multiple childbearing characteristics cluster together...

Racial and ethnic inequality continues to be the subject of considerable public interest. We shed light on this issue by examining racial disparities in the prevalence of several types of hardship, such as trouble paying bills and housing problems, in the USA over the 1992-2019 period. Using data from several panels of the Survey of Income and Program Participation, we find that hardships were considerably higher-sometimes double, depending on the measure-among blacks and Hispanics than whites and Asians. Nevertheless, these disparities generally narrowed over time...

As postponement of first births continues in the United States, women and couples will likely continue to turn to assisted reproductive technologies (ART) to overcome biological barriers to childbearing. This paper uses stochastic projections to estimate the potential impacts of ART on the US total fertility rate (TFR) overall and across sociodemographic groups using publicly available data. Assuming the trends in ART continue and the TFR remains at the mean estimate, the projection shows the ART TFR will rise from 0...

In the United States, high marital instability calls for more research on union transitions after marital dissolution. Previous studies focus on remarriage and pay little attention to rising post-dissolution cohabitation. In this study, I apply marital search theory to examine the level, pace, and differentials of repartnering (remarriage or cohabitation vs. staying single) and the exit from cohabitation (remarriage or dissolution vs. staying cohabiting). Adopting union history data from the pooled National Survey of Family Growth (2011-2017), I track union transitions among a sample of N = 2129 women...

A preference for sons and a sex selection against females are widespread in vast regions of the world, including a great number of Asian and East European countries. However, while a robust son bias has been widely studied in several countries of these regions, much less attention has been given to other regions, such as Latin America. The aim of this paper is to compare gender preferences in twelve selected countries of Southeast Asia and Latin America at the beginning of the 21st century by calculating to what extent parents adapt their fertility behaviors to ensure the birth of a preferred sex...

Sexual minority women face a plethora of structural, socioeconomic, and interpersonal disadvantages and stressors. Research has established negative associations between women's sexual minority identities and both their own health and their infants' birth outcomes. Yet a separate body of scholarship has documented similarities in the development and well-being of children living with same-sex couples relative to those living with similarly situated different-sex couples. This study sought to reconcile these literatures by examining the association between maternal sexual identity and child health at ages 5-18 using a US sample from the full population of children of sexual minority women, including those who identify as mostly heterosexual, bisexual, or lesbian, regardless of partner sex or gender...

The combined effects of declining fertility and increased longevity have accelerated population aging in different parts of the world. Unlike other countries, Puerto Rico is also experiencing unprecedented levels of working-age out-migration. The full impact of high out-migration on Puerto Rican demography is not fully understood. Placing Puerto Rico's aging process in an international context is useful in identifying the role out-migration is having on the accelerated aging of the Puerto Rican society. Using the World Population Prospects 2019 estimates, we compared the pattern of rapid aging found for Puerto Rico with the trajectories of six other countries with the highest population of 65+ in the World, Europe, and the Caribbean from 1960 to 2020...

The Census Bureau plans a new approach to disclosure control for the 2020 census that will add noise to every statistic the agency produces for places below the state level. The Bureau argues the new approach is needed because the confidentiality of census responses is threatened by "database reconstruction," a technique for inferring individual-level responses from tabular data. The Census Bureau constructed hypothetical individual-level census responses from public 2010 tabular data and matched them to internal census records and to outside sources...

Traditional dependency ratios based on the United Nations' old age definition (≥ 65 years) appear to be an inappropriate indicator for many developing countries, including Bangladesh. Bangladesh, with a retirement age of 59 in many sectors, defines old age as ≥ 60 years, whereas the United Nations documents 60-64 years as working age. This study offers two modifications to the traditional formulas of dependency ratios and compares the modified measures against the traditional measures from 1975 to 2100...

Despite the sizeable impact of migration on childbearing, less is known about how it shapes contraceptive use undergirding fertility. We utilize binational survey data collected in 2006/7 by the Migration, Gender, and Health among Immigrant Latinos in Durham, NC study to assess how selection, disruption, and adaptation shape contraceptive use among Mexican migrant women. We address selectivity with respect to both socio-demographic and formative sexual initiation characteristics, comparing migrants to non-migrants in Mexico...
