It’s sometimes said that “the past is a foreign country.” That may be the feeling you get when you look at these photographs below, of America during the Great Depression and the years immediately following.

The U.S. in the 1930s was a very different place, as the photos show. In terms of per capita income, the U.S. then was poorer than Mexico is today. The Civil Rights movement had not yet occurred, and Jim Crow laws still ruled the South. Women had been voting in national elections for fewer than two decades.

The photographers who snapped these images were charged with documenting America, often its poor and vulnerable communities. The project, sponsored by the United States Farm Security Administration and Office of War Information between 1935 to 1945, was meant to build support for government programs, such as Franklin Delano Roosevelt’s Resettlement Administration act of 1935, which aided the poorest third of farmers displaced by the Great Depression. It is the largest photography project ever sponsored by the U.S. government.

The Library of Congress has maintained and cataloged the collection, and Photogrammar, a site run by Yale University, now hosts 170,000 of the photographs.

The photos immediately below are some selected shots from New York, L.A., Washington, D.C., and Chicago. You can see more photos, including some from Texas, in the slideshow below.
