Social documentary photography  Social documentary photography or concerned photography is the recording of what the world looks like, with a social and/or environmental focus. It is a form of documentary photography, with the aim to draw the public's attention to ongoing social issues. It may also refer to a socially critical genre of photography dedicated to showing the life of underprivileged or disadvantaged people. Social documentary photography has its roots in the 19th Century work of Henry Mayhew, Jacob Riis, and Lewis Hine, but began to take further form through the photographic practice of the Farm Security Administration (FSA) in the USA. The FSA hired photographers and writers to report and document the plight of poor farmers. Under Roy Stryker, the Information Division of the FSA adopted a goal of "introducing America to Americans." Many noted Depression-era photographers were fostered by the FSA project, including Walker Evans, Dorothea Lange, and Gordon Parks. The photographers documented the situation of poor farmers, whose economic existence was threatened, and created a new style with photographic documentation of social problems. FSA made 250,000 images of rural poverty, but only about half survive. These are now housed in the Prints and Photographs Division of the Library of Congress and online. From these some 77,000 different finished photographic prints were originally made for the press, plus 644 color images from 1,600 color negatives. Social documentary photography or concerned photography may often be devoted to 'social groups' with socio-economic and cultural similarities, showing living or working conditions perceived as shameful, discriminatory, unjust or harmful. Examples include child labor, child neglect, homelessness, poverty among segments of society, impoverished children and the elderly, and hazardous working conditions. The poor, the social outcasts, or lower classes are portrayed in compassionate observation. The documentary power of the images is associated with the desire for political and social change. As early as in the 19th century the living conditions for the lower classes were the subject of photography. Henry Mayhew photographed the book London Labour and the London Poor, a representation of the depiction of London's working class. The book was illustrated by woodcuts, from photographs by Beard. Thomas Annan published "Photographs of the Old Closes and Streets of Glasgow, 1868-77", a documentation of the slum areas in Glasgow. Yet another example is the book published by Smith and Thompson in 1877 "Street Life in London", which also documented social life. England was the birthplace of social documentary photography, given the advanced stage of industrialization, and its impact on society.
