The impact of the COVID-19 pandemic on the Hispanic population resulted in the almost complete elimination of the long-standing Hispanic mortality advantage relative to the non-Hispanic White population. However, it is unknown how COVID-19 mortality affected the diverse Hispanic subpopulations.

The role of smoking in racial disparities in mortality and life expectancy in the United States has been examined previously, but up-to-date estimates are generally unavailable, even though smoking prevalence has declined in recent decades.

Recent data suggest that overall divorce rates in the United States have been declining since the 1980s, while research examining marriages formed prior to 2004 suggests that divorce rates historically have not declined equally across the socioeconomic spectrum. Understanding recent differentials by education helps explore growing inequality over time given the well-documented negative consequences of divorce for women.

As many as one-in-three unintended births occur in Africa. These births have the potential to adversely impact women's health, but data and design limitations have complicated efforts to understand their consequences. Moreover, there is growing evidence that women often feel happy about an unintended pregnancy and this heterogeneity may be important for identifying the births that are - and those that are not - harmful to women's health.

There has been little systematic research on the mortality impact of COVID-19 in the Native American population.

Greater levels of education are associated with lower risk of dementia, but less is known about how education is also associated with the compression of dementia incidence.

A growing body of literature has reported widening educational health disparities across birth cohorts or time periods in the United States, but has paid little attention to the implication of mortality selection on the cohort trend in health disparities.

Latin America has high rates of single motherhood and intergenerational coresidence, resulting in children experiencing changes in household composition - particularly with respect to fathers and grandparents. In other contexts, such changes have been shown to influence educational outcomes.

Life expectancy is a pure measure of the mortality conditions faced by a population, unaffected by that population's age structure. The numerical value of life expectancy also has an intuitive interpretation, conditional on some assumptions, as the expected age at death of an average newborn. This intuitive interpretation gives life expectancy a broad appeal. Changes in life expectancy are also routinely used to assess mortality trends. Interpreting these changes is not straightforward as the assumptions underpinning the intuitive interpretation of life expectancy are no longer valid. This is particularly problematic during mortality 'shocks,' such as during wars or pandemics, when mortality changes may be sudden, temporary, and contrary to secular trends.

While the use of standard errors and confidence intervals is common in regression-based studies in the population sciences, it is far less common in studies using formal demographic measures and methods, including demographic decompositions.

The increasing prevalence of frailty in aging populations represents a major social and public health challenge which warrants a better understanding of the contribution of frailty to the morbid process.

To compare fertility in India to both low-to-middle-income and high-income countries (LMICs and HICs) and describe the patterns that have accompanied India's transition to low fertility.

To investigate the mortality impact of the COVID-19 pandemic on US-born and foreign-born populations by race and Hispanic origin in the United States in 2020.

Smoking is a leading cause of premature death across contemporary developed nations, but few longitudinal individual-level studies have examined the long-term health consequences of exposure to smoking.

Contacts with the criminal legal system have consequences for a host of outcomes. Still, early life age patterns of system involvement remain to be better understood.

While recent decades have seen gradual convergence in ethno-racial disparities in completed fertility in the United States, differences in the age pattern of first births remain. The role of nativity has not been fully understood.

A classic debate concerns whether absolute or relative income is more salient. values resources as constant across time and place while contextualizes one's hierarchical location in the distribution of a time and place.

Wilson (1987) argued that race differences in the frequency of marriage from the 1960s to the 1980s resulted from a shortage of marriageable men in the Black community. A large literature used spatially defined measures of male marriageability to predict marriage rates of women. These studies concluded that the availability of marriageable men can explain only a fraction of race differences in marriage. I argue that this finding may reflect errors in the measurement of the availability of marriageable spouses.

Longitudinal data available for studying fertility in the United States are not representative at the state level, limiting analyses of subnational variation in US fertility. The US Census Bureau makes available restricted data that may be used for measuring fertility, but the data have not previously been described for a scholarly audience or used for fertility research.

Despite rapidly rising female educational attainment and the closing, if not reversal, of the gender gap in education, female labor force participation rates in the Middle East and North Africa (MENA) region remain low and stagnant. This is a phenomenon that has come to be known as the "MENA paradox". Even if increases in participation are observed, they are typically in the form of rising unemployment rather than employment.

The amount of literature on environmental migration is increasing. However, existing studies exhibit contradictory results. A systematic synthesis of the environment-migration relationship is much needed.
