1904 or 61 cents/day for 1932 for an urban worker in New York.

1917...the careful studies of infant mortality by the Federal Children's Bureau... In a steel manufacturing town, Johnstown, Pa., for example, it was found that unless the family had an annual income of about $800 or more, the death rate among infants was considerably above the average
1918, Sydenstricker, Public Health Statistician in the U.S. Public Health Service...disabling illnesses among Southern cotton-mill workers. They found that the proportion of working days lost due to disabling sickness was significantly higher... for workers below a particular equivalent-income level...determined that this equivalent-income level would be equivalent to about $900 a year for the "normal" family of five persons in "typical communities elsewhere in the United States."

The Federal Government set unofficial poverty guidelines during the Depression, such as the WPA "emergency budget."

The emergency budget was "a direct concession to conditions produced by the depression, constructed...--yet "those forced to exist at the emergency level for an extended period may be subjected to serious health hazards."...

At March 1935 prices, the average annual cost of the emergency budget (based on the unweighted average of figures for the 59 cities) was $903.27

This is 63 cents/day. The RDEU was considered NOT appropriate for long time use, since it was nutritionally insufficient. The WPA set these guidelines to attempt to help
