  • Pregnancy Intentions, Race and Ethnicity, and Infant Outcomes: A Research Note

    Open Access•Nicholas D E Mark•ARTICLE•Demography•2026

    Highlights “Unintended” pregnancies are commonly thought to be associated with worse infant health outcomes than “intended” pregnancies. These associations are strongest among White mothers and are weak or not significant among Black and Hispanic mothers. Adjusting for a basic set of sociodemographic variables dramatically changes the relationship between pregnancy intention and outcomes for Whites but not for other racial and ethnic groups. The …

  • The Effect of the Great Recession on U.S. Fertility: Causal Estimates From a Novel Cohort Discontinuity Design

    Open Access•Lawrence Wu, Nicholas D E Mark et al.•ARTICLE•Demography•2026

    Highlights This article presents causal effects of the Great Recession on U.S. fertility. Effects are identified using a new cohort discontinuity design. The design identifies effects for single-year cohorts of women, as well as for single-year cohorts of White and Black women. Estimated effects are negative for U.S. women born in the period 1964‒1992. Negative effects are largest for younger cohorts and for Black women

  • Severe Tornadoes and Infant Birth Weight in the United States

    Open Access•Nicholas D E Mark, E J Raker et al.•ARTICLE•Demography•2025•References: 43

    Increasing evidence links exposure to extreme weather events in utero with adverse health outcomes at birth, including lower birth weight. This research, however, often faces data limitations because natural disasters may be localized, often affecting some neighborhoods but not others, whereas outcome data are often available only at higher geographic levels, such as counties. In this article, we introduce a novel strategy for estimating the effe…

  • Racial/Ethnic Differences in Relationships Between Pregnancy Intentions and Maternal Outcomes

    Open Access•Nicholas D E Mark•ARTICLE•Maternal and Child Health Journal•2024

  • Fear among Hispanic and Non-Hispanic White Youth in Texas during a Period of Punitive Immigration Policies (2009–2017)

    Open Access•Nicholas D E Mark, A Weitzman et al.•ARTICLE•Socius Sociological Research for…•2024•References: 3

    Heightened partisan rhetoric surrounding immigration, combined with increasingly punitive immigration policies, has the potential to affect how children interact with their social environment, with implications for racially and spatially variegated developmental processes. In this data visualization, the authors use data from the 2009 to 2017 waves of the National Crime Victimization Survey’s School Crime Supplement to show that Hispanic students…

  • Reexamining the causes of age patterns in Black-White birth weight disparities: Evidence from U.S. cohorts

    Open Access•Nicholas D E Mark•ARTICLE•Social Science Research•2024•References: 77

  • Pregnancy intentions' relationship with infant, pregnancy, maternal, and early childhood outcomes: Evidence from births in Alaska, Missouri, and Oklahoma

    Open Access•Erica Hobby, Nicholas D E Mark et al.•ARTICLE•Perspectives on Sexual and…•2023•Cited by: 1•References: 1

    Our findings suggest that pregnancy intention is less consequential for maternal and child well-being than socio-economic disadvantage, suggesting that re-orienting policy toward social conditions and reproductive autonomy will serve better individual and population health

  • Is US Fertility now Below Replacement? Evidence from Period vs. Cohort Trends

    Open Access•Lawrence Wu, Nicholas D E Mark•ARTICLE•Population Research and Policy…•2023•Cited by: 2•References: 23

    In this study, we contrast period and cohort approaches to answering the question: Is US fertility now below replacement? The answer would appear to be an unambiguous “yes” based on period trends in the total fertility rate (TFR). Since 2007, TFR has declined from 2.12, just above the replacement level set by demographic tradition at 2.10 births per woman, to 1.67 in 2022, leading many to speculate that the United States has now entered a sustain…

  • Choosing Alone? Peer Continuity Disparities in Choice-Based Enrollment Systems

    Open Access•Nicholas D E Mark, Sean P Corcoran et al.•ARTICLE•Educational Researcher•2023•References: 39

    We provide novel evidence on the broader impacts of school choice systems by quantifying disparities in peer continuity from middle to high school in New York City. We find that Black and Hispanic students and those in high-poverty neighborhoods attend high school with a much smaller fraction of their middle school or neighborhood peers than their White, Asian, and low-poverty neighborhood counterparts. Disparities also emerge in peer isolation: …

  • Student absenteeism and the role of police encounters

    Open Access•Amanda Geller, Nicholas D E Mark•ARTICLE•Criminology & Public Policy•2022•References: 12

    Research Summary Using data from the Fragile Families and Child Wellbeing Study, we estimated associations between adolescent–police contact and several measures of school absenteeism. Adolescents self‐reported absences due to health and due to truancy; police contact was linked to both. Youth reporting police contact were absent approximately 2.2 more days in total than those not reporting contact. Police contact was also associated with a 10 pe…

  • Do Pregnancy Intentions Matter? A Research Note Revisiting Relationships Among Pregnancy, Birth, and Maternal Outcomes

    Open Access•Nicholas D E Mark, K Cowan•ARTICLE•Demography•2022•Cited by: 12•References: 34

    The prevention of unplanned or unintended pregnancies continues to be a cornerstone of U.S. reproductive health policy, but the evidence that such pregnancies cause adverse maternal and child outcomes is limited. In this research note, we examine these relationships using recent large-scale data and inverse propensity weights estimated from generalized boosted models. We find that pregnancy timing is related to maternal experience during pregnanc…

  • Adding Insult to Injury: Arrests Reduce Attendance through Institutional Mechanisms

    Open Access•Nicholas D E Mark, Amanda Geller et al.•ARTICLE•Sociology of Education•2022•Cited by: 4•References: 74

    Students across the United States experience high levels of contact with the police. To clarify the causal relationships of this contact with educational outcomes and the mechanisms by which such relationships arise, we estimate the effects of arrest on student engagement with school using daily attendance data. Recently arrested students missed significantly more school than did students who would be arrested later in the school year. The effect…

  • Whither weathering? The variable significance of age in Black-White low birth weight disparities

    Open Access•Nicholas D E Mark•ARTICLE•SSM - Population Health•2021

    This paper uses birth certificate data to provide novel estimates of the age-specific risk of a low birth weight birth (LBW, an infant born weighting <2500 g) for U.S.-born non-Hispanic Black and White mothers, and finds that patterns vary markedly over space and time. Notably, risk of an LBW birth for Black mothers increased much more steeply with age in 1991-94 than in 2014-17. This decline in LBW risks among older Black mothers led to a declin…

  • Covid-19 Vaccine Hesitancy Is the New Terrain for Political Division among Americans

    Open Access•K Cowan, Nicholas D E Mark et al.•ARTICLE•Socius Sociological Research for…•2021•Cited by: 15•References: 5

    Politically conservative Americans are less likely than those who identify as liberal to report a willingness to get a vaccine against coronavirus disease 2019. Using data from the Axios/Ipsos Coronavirus Survey from November 2020 to February 2021, the authors find that this partisan divide in vaccine hesitancy has increased over time. Recent scholarship has suggested that these differences can be attributed to personal characteristics, including…

  • Sexual Abstinence in the United States: Cohort Trends in Abstaining from Sex While Never Married for U.S. Women Born 1938 to 1983

    Open Access•Lawrence Wu, Steven P Martins et al.•ARTICLE•Socius Sociological Research for…•2020•Cited by: 1

    In this data visualization, the authors document trends in abstaining from sex while never married for U.S. women born 1938–1939 to 1982–1983. Using data from the six most recent National Surveys of Family Growth, the authors’ estimates suggest that for women born in the late 1930s and early 1940s, 48 percent to 58 percent reported abstaining from sex while never married. Abstinence then declined rapidly among women born in the late 1940s through…
