Mapping the Dust Bowl Migration

by James Gregory

The press called them Dust Bowl refugees, although actually few came from the area devastated by dust storms. Instead they came from a broad area encompassing five southern plains states: Oklahoma, Texas, Arkansas, Kansas, and Missouri. More than half a million left the region in the 1930s, heading for California and other western states. Below are interactive maps and charts that show various dimensions of the Dust Bowl Migration to California and the West. The first shows the number of migrants who settled in California between 1935 and 1940. Another shows county by county where the migrants settled. The maps are hosted by Tableau Public.

African American Great Migration

 

Upwards of 7 million African Americans left the South during the 20th century, settling mostly in the big cities of the North and West. In doing so they transformed more than their own lives. This Great Migration transformed cities and set the foundations for reconstructions of race, politics, and even the regional balances of the nation. This section includes six interactive maps and charts.

Here are charts and tables showing who moved to each state and who left each state. Using birthplace information, we track decade-by-decade the population origins of California, Florida, Texas, Illinois, New York, Hawaii, and every other state, showing countries of birth and states of birth. Secondly, we show where people from each state settled, how many stayed and how many left.
