In the first half of the twentieth century, the rate of death from infectious disease in the United States fell precipitously. Although this decline is well-known and well-documented, there is surprisingly little evidence about whether it took place uniformly across the regions of the U.S. We...

In the United States, people with more education vote more. But, we know little about why education increases political participation or whether higher-quality education increases civic participation. We study applicants to Boston charter schools, using school lotteries to estimate charter...

The 1921 Tulsa Race Massacre resulted in the looting, burning, and leveling of 35 square blocks of a once-thriving Black neighborhood. Not only did this lead to severe economic loss, but the massacre also sent a warning to Black individuals across the country that similar events were possible in...

AT&T was the largest U.S. firm for most of the 20th century. Telephone operators once comprised over 50% of its workforce, but in the late 1910s it initiated a decades-long process of automating telephone operation with mechanical call switching--a technology first invented in the 1880s. We...

The recent digitization of complete count census data is an extraordinary opportunity for social scientists to create large longitudinal datasets by linking individuals from one census to another or from other sources to the census. We evaluate different automated methods for record linkage,...

We link future members of Congress to the de-anonymized 1940 census to offer a uniquely detailed analysis of how economically unrepresentative American politicians were in the 20th century, and why. Future members under the age of 18 in 1940 grew up in households with parents who earned more...

What was the return to education in the United States at mid-century? In 1940, the correlation between years of schooling and earnings was relatively low, less than it had been in 1915 or than it would be in later decades. In this paper, we estimate the causal return to schooling in 1940,...

Using General William Sherman's 1864-65 military march through Georgia, South Carolina, and North Carolina during the American Civil War, this paper studies the effect of capital destruction on medium and long-run local economic activity, and the role of financial markets in the recovery...

Fears of immigrants as a threat to public health have a long and sordid history. At the turn of the 20th century, when millions of immigrants crowded into dense American cities, contemporaries blamed the high urban mortality penalty on the newest arrivals. Nativist sentiments eventually led to...

We explored two measures of inequality that described the full income distribution in cities. One measure is an income gini based on family incomes in 1929 for 33 cities and in 1933 for up to 48 cities in 1933 were spread throughout the country. We also estimated gini coefficients that made use...
