The federal government required contributions from individual states, and authorized state discretion to determine who received aid and in what amount. ADC was primarily created for white single mothers, who were expected not to work. Black mothers, who had always been in the labor force, were not considered eligible to receive benefits. In 1961 a change in the law permitted states to extend benefits to families where the father was unemployed, a measure which 25 states eventually adopted. The words "families with" were added to the name in 1962, partly due to concern that the program's rules discouraged marriage.
