Prohibition Movement in the United States, 1801-1920

These data were gathered for use in modeling the diffusion of prohibition in the United States throughout the nineteenth century. The study contains information on the prohibition status of counties from 1801 to 1920. For each county in the continental United States, the prohibition status is recorded annually starting with 1801. For those counties that were established after 1801, the prohibition status is recorded from the date the county was created. State-level prohibition status is also identified.
