One of the most difficult problems in the social sciences is measuring the policy climate in societies. Prior to the 1930s the vast majority of labor regulations in the U.S. were enacted at the state level. In this paper we develop several summary measures of labor regulation that document the...

The Great Migration–the massive migration of African Americans out of the rural South to largely urban locations in the North, Midwest, and West–was a landmark event in US history. Our paper shows that this migration increased mortality of African Americans born in the early twentieth...

This paper examines the effect of waterborne lead exposure on infant mortality in American cities over the period 1900 to 1920. Variation across cities in water acidity and the types of service pipes, which together determined the extent of lead exposure, identifies the effects of lead on infant...

The 1960s ushered in a new era in US demographic history characterized by significantly lower fertility rates and smaller family sizes. What catalyzed these changes remains a matter of considerable debate. This paper exploits idiosyncratic variation in the language of "Comstock" statutes,...

A striking negative correlation exists between an area's residential racial segregation and its population characteristics, but it is recognized that this relationship may not be causal. I present a novel test of causality from segregation to population characteristics by exploiting the...

The link between circumstances faced by individuals early in life (including those encountered in utero) and later life outcomes has been of increasing interest since the work of Barker in the 1970s on birth weight and adult disease. We provide such a life course perspective for the U.S. by...

This paper reviews recent literature using stature and weight as measures of human welfare with a particular interest in cliometric or historical research. We begin with an overview of anthropometric evidence of living standards and the new but fast-growing field of anthropometric history. This...

This paper examines the effect of water-borne lead exposure on infant mortality in American cities over the period 1900-1920. Infants are highly sensitive to lead, and more broadly are a marker for current environmental conditions. The effects of lead on infant mortality are identified by...

This paper addresses revolutionary changes in the education, fertility and market work of U.S. families formed in the 1870s-1920s: Fertility fell from 5.3 to 2.6; the graduation rate of their children increased from 7 to 50 percent; and the fraction of adulthood wives devoted to market-oriented...

Historical wealth micro-data from Wentworth County, Ontario examines the evolution of female and male wealth holding in the wake of 19th century property rights legislation. The results reveal that male wealth was greater than female wealth in Wentworth County but that over time the gap...
