We discover and document errors in public use microdata samples ("PUMS files") of the 2000 Census, the 2003-2006 American Community Survey, and the 2004-2009 Current Population Survey. For women and men ages 65 and older, age- and sex-specific population estimates generated from the PUMS files...

This paper examines how marital and fertility patterns have changed along racial and educational lines for men and women. Historically, women with more education have been the least likely to marry and have children, but this marriage gap has eroded as the returns to marriage have changed....

Between 1972 and 1978 U.S. high schools rapidly increased their female athletic participation rates - to approximately the same level as their male athletic participation rates - in order to comply with Title IX, a policy change that provides a unique quasi-experiment in female athletic...

Trends in BMI values are estimated by centiles of the US adult population by birth cohorts 1886-1986 stratified by ethnicity. The highest centile increased by some 18 to 22 units in the course of the century while the lowest ones increased by merely 1 to 3 units. Hence, the BMI distribution...

Background: The trend in the BMI values of the US population has not been estimated accurately because time series data are unavailable and because the focus has been on calculating period effects. Object: To estimate the trend and rate of change of BMI values by birth cohorts stratified by...

We document that trust in public institutions - and particularly trust in banks, business and government - has declined over recent years. U.S. time series evidence suggests that this partly reflects the pro-cyclical nature of trust in institutions. Cross-country comparisons reveal a clear...

The trend of the height of Indian scouts in the U.S. Army born between ca. 1825 and 1875 is analyzed. Their average height of ca. 170 cm (67 in.) confirms that natives were tall compared to Europeans but were nearly the shortest among the rural populations in the New World. The trend in their...

Progress in closing differences in many objective outcomes for blacks relative to whites has slowed, and even worsened, over the past three decades. However, over this period the racial gap in well-being has shrunk. In the early 1970s data revealed much lower levels of subjective well-being...
