The report, culminating a year long study of the ADC program in Cook county by a New York City welfare consulting firm, listed 10 long range recommendations designed to reduce the soaring ADC case load. The report called racial discrimination in employment ``one of the most serious causes of family breakdown, desertion, and ADC dependency.''

The monthly cost of ADC to more than 100000 recipients in the county is 4.4 million dollars, said C. Virgil Martin, president of Carson Pirie Scott + Co., committee chairman.

``We must solve the problems which have forced these people to depend upon ADC for subsistence,'' Martin said.

The volume of ADC cases will decrease, Martin reported, when the community is able to deal effectively with two problems: Relatively limited skills and discrimination in employment because of color. These, he said, are ``two of the principal underlying causes for family breakups leading to ADC.''

Other recommendations made by the committee are:

Extension of the ADC program to all children in need living with any relatives, including both parents, as a means of preserving family unity.

Research projects as soon as possible on the causes and prevention of dependency and illegitimacy.
