History: Dust Bowl, Dirty Thirties, 1930s, Great Plains, American And Canadian Prairies

When James N. Gregory examined the Census Bureau statistics, as well as other surveys, he discovered some surprising percentages. For example, in 1939, the Bureau of Agricultural Economics surveyed the occupations of about 116,000 families who had arrived in California in the 1930s. It showed that only 43 percent of southwesterners were doing farm work immediately before they migrated. Nearly one-third of all migrants were professional or white-collar workers. The poor economy brought more than just farmers as refugees to California; many teachers, lawyers, and small business owners moved west with their families during this time. After the Great Depression ended, some moved back to their original states, but many remained where they had started their new lives. In fact, around one-eighth of California's population is of Okie heritage.
U.S. Government response
During President Franklin D. Roosevelt's first 100 days in office in 1933, governmental programs designed to conserve soil and restore the ecological balance of the nation were implemented. Interior Secretary Harold L. Ickes established the Soil Erosion Service in August 1933 under Hugh Hammond Bennett. In 1935, it was transferred and reorganized under the Department of Agriculture and renamed the Soil Conservation Service. More recently, it has been renamed the Natural Resources Conservation Service (NRCS). As part of New Deal programs, Congress passed the Soil Conservation and Domestic Allotment Act in 1936, requiring landowners to share the allocated government subsidies with the laborers who worked on their farms. Under the law, "benefit payments were continued as measures for production control and income support, but they were now financed by direct Congressional appropriations and justified as soil conservation measures. The Act shifted the parity goal from price equality of agricultural commodities and the articles that farmers buy to income equality of farm and non-farm population." Thus, the parity goal was to re-create the ratio between the purchasing power of the net income per person on farms from agriculture and that of the income of persons not on farms that prevailed during 1909–1914.
