RESUMEN
In this study, we provide an assessment of data accuracy from the 2020 Census. We compare block-level population totals from a sample of 173 census blocks in California across three sources: (1) the 2020 Census, which has been infused with error to protect respondent confidentiality; (2) the California Neighborhoods Count, the first independent enumeration survey of census blocks; and (3) projections based on the 2010 Census and subsequent American Community Surveys. We find that, on average, total population counts provided by the U.S. Census Bureau at the block level for the 2020 Census are not biased in any consistent direction. However, subpopulation totals defined by age, race, and ethnicity are highly variable. Additionally, we find that inconsistencies across the three sources are amplified in large blocks defined in terms of land area or by total housing units, blocks in suburban areas, and blocks that lack broadband access.

BACKGROUND: Self-rated health (SRH) is one of the most commonly used summary measures of overall health and well-being available to population scientists due to its ease of administration in large-scale surveys and to its efficacy in predicting mortality. This paper assesses the extent to which SRH is affected by its placement before or after questions about bodyweight on a survey, and whether differences in placement on the questionnaire affects SRH's predictive validity. METHODS: I assessed the validity of SRH in predicting the risk of mortality by comparing outcomes of sample members who were asked to rate their health before reporting on their bodyweight (the control group) and sample members who were asked to rate their health after reporting on their bodyweight (the treatment group). Both the control and treatment group were randomly assigned via an experiment administered as a module in a nationally representative sample of adults in the USA in 2019 (N = 2523). RESULTS: The odds of reporting a more favorable appraisal of health are 30% lower for sample members who were in the treatment group when compared with the control group. Additionally, the SRH of treatment group members is significantly associated with their risk of mortality, while the SRH of control group members is not. CONCLUSION: The findings from this study suggest that for researchers to maximize the utility of SRH, closer attention needs to be paid to the context of the survey within which it asked. SRH is highly sensitive to the questions that precede it, and this sensitivity may in turn mischaracterize the true health of the population that the survey is intending to measure.

Using 15 years of student enrollment histories from administrative data spanning the 2004-05 through 2018-19 school years at all public colleges, universities, and technical/trade schools in the state of Ohio, we examine rates of re-enrollment in postsecondary education for individuals pursuing additional credentials following the receipt of a sub-baccalaureate certificate. We find that the majority of certificate recipients re-enroll to continue their progression toward stacking credentials. The likelihood of re-enrollment diminishes for certificate earners as they get further out from the term when their initial certificate was completed. Certificate earners re-enroll at an accelerated rate if they acquired their initial certificate at a community college, if they currently have low wages at their jobs, and following increases in local unemployment rates. Our findings lend support to sociological ideas about the role of institutional contexts, opportunity costs, and labor market opportunities in shaping non-traditional postsecondary pathways across the life course.

Using a nationally representative sample of 1,189 immigrant youth in American high schools, we examine whether the quality of education in their country of origin is related to post-migration math achievement in the 9th grade. To measure the quality of their education in the country of origin, we use country-specific average test scores from two international assessments: the Programme for International Student Assessment (PISA) and the Trends in International Mathematics and Science Study (TIMSS). We find that the average PISA or TIMSS scores for immigrant youth's country of origin are positively associated with their performance on the 9th grade post-migration math assessment. We also find that each year spent in the United States is positively associated with performance on the 9th grade post-migration math assessment, but this effect is strongest for immigrants from countries with low PISA/TIMSS scores.

In the United States, natural disasters have increased in frequency and intensity, causing significant damage to communities, infrastructure, and human life. Migrant workers form part of a growing occupational group that rebuilds in the aftermath of natural disasters like hurricanes and tornadoes. The work these migrant workers perform is essential but also unstable, exploitative, and dangerous, which stresses their health and well-being. This study focuses on the health and well-being of migrant roofers, a precarious occupational group who restores communities and helps the U.S. population adjust to a climate-changed world. Using surveys (N = 359) and in-depth interviews (n = 58) from a convenience sample of migrant roofers, we examine how precarity in terms of employment, housing, and legal status affect the sleep outcomes of these workers, who derive their income from an industry where instability is the norm, live in substandard and irregular housing, and lack workplace protections given their legal status.
RESUMEN
Evidence suggests that lesbian and gay young adults use substances more frequently than their heterosexual peers. Based on the life course perspective, we argue that this difference may be due to the unavailability of marriage as a turning point in the lives of lesbian/gay young adults. We use data from a nationally representative sample of youth (N = 13,581, 52.4% female, 68.6% white, ages 18-26) to examine sexual orientation differences in substance use and explore whether these differences vary by romantic partnership formation in young adulthood. We find that the formation of more serious partnerships (e.g., cohabitation, marriage) is associated with less frequent substance use among heterosexual young adults, though this pattern does not hold for lesbian and gay young adults. We conclude that the partnership options available to lesbians and gay men do not provide the same health-protective benefits that marriage does for heterosexuals.

In this study I examine local variation in the timing and magnitude of the excess mortality hump, which is the period in adolescence and in young adulthood when mortality rates spike in young men due to an increase in risk-taking behaviors believed to result from a surge of testosterone production and subsequent aggressive, impulsive behaviors. Using an ecological framework and data on all-cause mortality in the United States between 2000 and 2018, I test the hypothesis that dimensions of the local population structure will exacerbate testosterone production and intraspecific competition among young men, which in turn leads to behaviors that elevate the risk of death. This hypothesis is supported by the data. I find that the age at the peak of the excess mortality hump is younger in counties where the sex ratio skews toward males and where population density is high. Additionally, I find that the overall magnitude of the peak of the excess mortality hump is greater in counties where the sex ratio skews toward males.

BACKGROUND: The relationship between men's testosterone levels and their sexual behaviors is unclear as existing studies find mixed results. OBJECTIVES: The key objective of this study is to assess whether men's testosterone levels are affected by sexual behaviors and to explore whether this relationship varies by age. Specifically, this study addresses the question: Are men's testosterone levels affected by the number of sexual partners they accrue? METHODS: This analysis was based on a nationally representative sample of 977 unpartnered heterosexual men between the ages of 20 and 65 in the United States. Serum testosterone levels were measured from blood samples using isotope dilution liquid chromatography tandem mass spectrometry and the number of sexual partners in the past 12 months was ascertained from an audio computer-assisted personal self-interview. Using ordinary least squares regression, serum testosterone levels were predicted as a function of the number of sexual partners that men reported, sociodemographic characteristics, and factors known to affect endocrine regulation. An interaction term between the number of sexual partners in the past 12 months and age was included. RESULTS: The correlation between the number of sexual partners in the past 12 months and testosterone levels is contingent upon age: The relationship is positive for younger men but negative for older men. Among 20-year-old unpartnered heterosexual men, an additional sexual partner in the past 12 months is associated with an increase of 5.55 ng/dl of testosterone (95% confidence interval (CI): 2.92, 8.19). This initial positive effect at age 20 is reduced by 0.25 ng/dl of testosterone (95% CI: -0.44, -0.06) with each year that men age. CONCLUSION: Testosterone levels in men are related to reproductive behaviors, but the direction of this relationship changes as men age.

Using data from the 2017-18 Health of Houston Survey, this study estimates the effect of Hurricane Harvey, the second costliest storm in the history of the United States, on the physical and mental health of adults living in Houston, Texas. The survey was fielded to a population-based probability sample whose data collection activities were interrupted and delayed by Hurricane Harvey. This interruption in data collection created a natural experiment that allowed for a comparison of community health before and after the storm. Following the storm, adults in Houston on average experienced an increase of 1.12 days a month of poor physical health and an increase of 1.31 days a month of poor mental health. These effects were most pronounced in parts of the city where structural damage from the storm was most severe.

There has been a growing concern among researchers and media commentators that men in the United States may be increasingly less sexually active, creating a form of a "sex recession." Using 14 years of survey data from men in the National Survey of Family Growth (2006-2019), this study assesses whether such concerns are warranted. Cross-classified mixed-effects models are estimated to ascertain whether there is evidence of a population-wide sex recession among men due to secular conditions specific to different time periods, or if birth cohorts that comprise the male population at any given point in time are exhibiting distinct patterns of sexual behavior. The analysis finds no evidence of a population-wide sex recession among men. Rates of sexual inactivity among men have been constant across the time series, but those born between 2000 and 2004 had significantly higher rates of sexual inactivity than previous birth cohorts did at the same age. Additionally, men who are unemployed and/or living at home with their parents are more likely to refrain from sexual intercourse than their peers who are employed and/or living independently of their parents.

STUDY OBJECTIVES: To estimate the effect of housing insecurity on sleep duration and sleep quality. METHODS: Using longitudinal data from a sample of 1,046 welfare recipients in the state of California followed from 2015-2016 through 2017-2018, we regressed self-reported measures of sleep duration and sleep quality recorded in 2017-2018 on experiences of housing insecurity in the prior year. We applied propensity score weights to attenuate potential bias from an array of observed covariates, including sleep duration and sleep quality measured prior to experiences with housing insecurity. RESULTS: Sample members who were unable to make their rent/mortgage payments slept on average 22 fewer minutes a night and had lower quality sleep than those who were able to make their rent/mortgage payments. Sample members who were forced to move because of an inability to make rent/mortgage payments slept on average 32 fewer minutes a night and had lower quality sleep than those who were not forced to move. CONCLUSIONS: By compromising sleep health, housing insecurity represents a distinct form of stress in the lives of economically-disadvantaged adults, which could also contribute to other health disparities.

In recent decades, several states have enacted their own immigration enforcement policies. This reflects substantial variation in the social environments faced by immigrants and native-born citizens, and has raised concerns about unintended consequences. E-Verify mandates, which require employers to use an electronic system to ascertain legal status as a pre-requisite for employment, are a common example of this trend. Drawing on birth certificate data from 2007-2014, during which 21 states enacted E-Verify mandates, we find that these mandates are associated with a decline in birthweight and gestational age for infants born to immigrant mothers with demographic profiles matching the undocumented population in their state as well as for infants of native-born mothers. In observing negative trends for both immigrants and natives, our findings do not support the hypothesis that E-Verify has a distinct impact on immigrant health; however, the broader economic, political, and demographic contexts that coincide with these policies, which likely impact the broader community of both immigrants and natives, may pose risks to infant health.
RESUMEN
Using a nationally representative sample of graduates from the high school class of 2003-2004, I test the warehouse hypothesis, which contends that youth are more likely to leave school and enter the labor force when there are available job opportunities (and vice versa). Using two measures of job opportunities--local unemployment rates and the percentage of local workers employed in jobs that require a bachelor's degree--I find support for the warehouse hypothesis. In areas where unemployment is low, with ample jobs that do not require a bachelor's degree, youth have higher odds of entering the labor force. In areas where unemployment is high, with few jobs that require only a high school diploma, youth have higher odds of entering college. The effect of unemployment on enrollment is more pronounced for low-income youth than for high-income youth, with both low- and high-income youth turning to four-year schools rather than two-year schools when job opportunities are limited.
