Age Heaping and Cancer Rate Estimation in Nigeria

Benjamin J.S. al-Haddad, Elima Jedy-Agba, Emmanual Oga & Clement Adebamowo
Age heaping is an important source of demographic bias in many countries. There is little scholarship on the effect of age heaping on cancer rate estimation. We use Nigerian demographic and cancer registry data to (1) quantify age heaping in states and within cancer registries using the Myers Blended Index and (2) examine the effect of residual age heaping bias on age standardized cancer rates (ASRs). We find severe age heaping at the level of...

The Temporal Dynamics and Stability of Black Migration to the South, 1970-2000: New Insights on Old Trends

Jack DeWaard, Katherine J. Curtis & Glenn V. Fuguitt
The “New Great Migration” of blacks to the South was and continues to be one of the most important demographic shifts in recent U.S. history, and refers to a black net-migration reversal in the South from negative to positive in the 1970s for the first time since before the Great Migration of blacks out of the region in the early and middle parts of the twentieth century. While prior research has told the story of...

The Impact of Divorce Legislation on Daily Time Allocation

Katie R. Genadek
Using time diary data from the mid-1970s, the relationship between unilateral divorce and couple-level time allocation is estimated. Married women in states with unilateral divorce are found to be spending less time in household production and core housework than those in states without unilateral divorce, and married men are found to be doing a greater share of housework within families. This paper also uses cross state and time variation in divorce law by including data...

Patriarchy, Power, and Pay: The Transformation of American Families, 1800–2015

Steven Ruggles
This article proposes explanations for the transformation of American families over the past two centuries. I describe the impact on families of the rise of male wage labor beginning in the nineteenth century and the rise of female wage labor in the twentieth century. I then examine the effects of decline in wage labor opportunities for young men and women during the past four decades. I present new estimates of a precipitous decline in the...

Parents' time with a partner in cross-national context: A comparison of the US, Spain, and France

Joan Garcia Roman, Sarah M. Flood & Katie Genadek
Time shared with a partner is an indicator of marital well-being and couples wants to spend time together. However, time with a partner depends on work and family arrangements as well as the policies, norms and values that prevail in society. Contrary to time spent with children, couples’ shared time in cross-national context is relatively unstudied. Previous studies from specific countries show that dual-earner couples spend less time together and that parents spend less time...

Historical Census Record Linkage

Steven Ruggles, Catherine Fitch & Evan Roberts
For the past 80 years, social scientists have been linking historical censuses across time to study economic and geographic mobility. In recent decades, the quantity of historical census record linkage has exploded, owing largely to the advent of new machine-readable data created by genealogical organizations. Investigators are examining economic and geographic mobility across multiple generations, but also engaging many new topics. Several analysts are exploring the effects of early-life socioeconomic conditions, environmental exposures, or natural...

Domestic Violence, Decision-Making Power and Female Employment in Colombia

Johanna Fajardo-Gonzalez
Using data from the Colombian Demographic and Health Survey, I study the relationship between domestic violence (DV) and women’s employment. I find a positive relationship between DV and employment, which persists when I exploit husband’s childhood experience of domestic violence as a source of plausibly exogenous variation for the incidence of DV. I find that the incidence of DV increases the likelihood of female employment by about 19 percentage points. To explore potential mechanisms underlying...

Through the NHGIS, users can download: 1) Boundary files for states and counties back to 1790, for census tracts back to 1910, and for all standard census units, including census blocks, since 1990, 2) Summary tables from all decennial censuses, the American Community Survey,...

Multidimensional Mortality Selection: Why Individual dimensions of Frailty Don't Ace Like Frailty

Elizabeth Wrigley-Field
Theoretical models of mortality selection have great utility in explaining otherwise puzzling phenomena. The most famous example may be the black-white mortality crossover: at old ages, blacks outlive whites, presumably because few frail blacks survive to old ages while some frail whites do. Yet theoretical models of unidimensional heterogeneity, or frailty, do not speak to the most common empirical situation for mortality researchers—where some important population heterogeneity is observed while some is not. I show...

Same-Sex Couples' Shared Time in the United States

Sarah M. Flood & Katie Genadek
Identification of same-sex couples in the American Time Use Survey (ATUS) is of increasing interest to the research community. While the ATUS surveys one person per household, using information about who else lives in the household, researchers can easily identify respondents in co-resident same-sex couple arrangements. Previous research has outlined two approaches to identifying same-sex couples in the ATUS that use information on the sex of household members. We extend that work by using additional...

Implications of Measurement: Comparing ATUS Estimates of Physical Activity to NHANES

Rachelle Hill, Sarah Flood & Kari Williams
Measuring physical activity reliably and accurately is challenging. The gold standard is limited because it is resource intensive. Accelerometer data has been used as a more accessible option but other less explored data such as time diary data could be a good alternative. Understanding how estimates differ by measurement strategy, including time diary data and accelerometer data, is thus an important contribution to the limited research base about physical activity measurement. Using nationally representative data...

U.S. Racial Inequality May Be as Deadly as COVID-19

Elizabeth Wrigley-Field
The Covid-19 pandemic is causing a catastrophic increase in U.S. mortality. How does the scale of this pandemic compare to another U.S. catastrophe: racial inequality? Using demographic models, I estimate how many excess white deaths would raise U.S. white mortality to the bestever (lowest) U.S. Black level under alternative, plausible assumptions about the age patterning of excess mortality in 2020. I find that nearly 400,000 excess white deaths would be needed to equal the best...
