This booklet reprints an article from the Proceedings of the Sixtieth Annual Session of the National Conference of Social Work in Detroit in June 1933.

One purpose of the article was to comment on the quality of the data. A second purpose was to present data derived from this first countrywide enumeration concerning the relative number of social workers in different parts of the country in comparison with other professional or near-professional groups.

This booklet presents the results of a study of salaries and certain related work conditions in the field of medical social work made by the Department of Statistics of the Russell Sage Foundation in 1937. The study's main purpose was to estimate the current salary levels for various positions in this type of social work and to indicate the variations in these levels. The study was a sequel to one made in 1933, which recorded a general decline in medical social work salaries from 1930 to 1933, and it was planned to show how much improvement, if any, had been realized by these workers during four years of recovery.
