In the mid-1930s, the Farm Security Administration’s Resettlement Administration hired photographers to document the work done by the agency. Some of the most powerful images were captured by photographer Dorothea Lange. Lange took this photo in New Mexico in 1935, noting, “It was conditions of this sort which forced many farmers to abandon the area.”

Arthur Rothstein was one of the first photographers to join the Farm Security Administration. His most noteworthy contribution during his five years with FSA may have been this photograph, showing a (supposedly posed) farmer walking in the face of a dust storm with his sons in Oklahoma, 1936.

Migrants from Texas, Oklahoma, Missouri, Arkansas and Mexico pick carrots on a California farm in 1937. A caption with Lange’s image reads, “We come from all states and we can’t make a dollar in this field noways. Working from seven in the morning until twelve noon, we earn an average of thirty-five cents.”

This Texas tenant farmer brought his family to Marysville, California in 1935. He shared his story with photographer Lange, saying, “1927 made $7000 in cotton. 1928 broke even. 1929 went in the hole. 1930 went in still deeper. 1931 lost everything. 1932 hit the road.”

A family of 22 set up camp alongside the highway in Bakersfield, California in 1935. The family told Lange they were without shelter, without water and were looking for work on cotton farms.

A pea picker’s makeshift home in Nipomo, California, 1936. Lange noted on the back of this photograph, “The condition of these people warrant resettlement camps for migrant agricultural workers.”

Among Dorothea Lange’s most iconic photos was of this woman in Nipomo, California in 1936. As a mother of seven at age 32, she worked as a pea picker to support her family.

The family who lived in this make-shift home, photographed in Coachella Valley, California in 1935, picked dates on a farm.

Californians derided the newcomers as “hillbillies,” “fruit tramps” and other names, but “Okie”—a term applied to migrants regardless of what state they came from—was the one that seemed to stick. The beginning of World War II would finally turn migrants’ fortunes as many headed to cities to work in factories as part of the war effort.

The Farm Security Administration (FSA) was created as part of the New Deal to build relief camps and offer loans and relocation assistance to farmers impacted by the Depression and the Dust Bowl. A photography unit, including New Jersey-born Dorothea Lange (whose photos are featured in this gallery), documented rural America for the agency.This photo shows a migrant family stalled in Texas with a flat tire on their way to Arkansas to find field work.

Lange’s access to the inner lives of struggling Americans was the result of patience and careful consideration of the people she photographed. Here, a field worker in Holtville, California shows shoes he had just made himself shoes out of an old tire.

Lange was best known for a series of photographs of Florence Owens Thompson, a 32-year-old mother living in a camp of stranded pea pickers.This photo of Thompson, “Migrant Mother,” came to symbolize the Great Depression.

Lange photographed this family of a turpentine worker near Cordele, Alabama. The father’s wages was $1 a day.

Migrant workers toiling a field. Lange’s colleague, Ron Partridge described how Lange would work, saying, “She would walk through the field and talk to people, asking simple questions—what are you picking? . . . How long have you been here? When do you eat lunch? . . . I’d like to photograph you, she’d say, and by now it would be ‘Sure, why not,’ and they would pose a little, but she would sort of ignore it, walk around until they forgot us and were back at work.”

Here, farmers in drought-stricken Oklahoma sit in the shade in August 1936.The FSA created a historical archive unlike any made before. By the time the project was finished, FSA photographers had taken some 250,000 photographs.

Arthur Rothstein was the first staff photographer hired to work for the Farm Security Administration. FSA photographers were tasked with documenting people’s living conditions in rural America so the images could be used to report back to Congress.Rothstein was born in New York City and studied at Columbia University. Here, Rothstein’s photo shows a woman spinning wool in Madison County, Arkansas.

As farmers and their families in Great Plains and the Midwest lost their homes and livelihoods in the Dust Bowl, many headed west to California. Once they reached the west, they were often derided as “fruit tamps” or “Okies.” This photo shows a migrant worker in the Yakima Valley, California. Rothstein once said he believed the role of documentary photographers was to “examine and scrutinize in order to reveal the truth.”

This photo shows evicted sharecroppers camping along Highway 60 in New Madrid County, Missouri. In 1935, 50 percent of all white farmers and 77 percent of all Black farmers were sharecroppers.

As drought depleted crops, many in the midwest abandoned their farms to move west or into North Dakota’s urban cities. This North Dakota farmer remained optimistic, according to photographer Rothstein.
