A study was conducted to determine a nationwide availability conclusion percentage of minorities (Blacks, Spanish-origin persons, Asian Americans, and American Indians) and women particularly in job groups of two job categories: Officials and Managers, and Professional. The resulting availability conclusions would then be used to determine underutilization of these minority groups in the two categories. Subsequent to compiling a list of government agencies, colleges, universities, and various associations and societies, over two hundred letters were written and visits were made to collect relevant statistical data. Government agencies provided the most complete and updated data while generally, the private associations, did not provide useful information. Utilizing the eight factors to be considered in determining the availability of minorities and women according to federal regulations, seven factors were identified and considered for both minorities and women in this study, including unemployment, labor force, and degree of training. (This report discusses in detail the methodologies, statistics for each of the availability factors, and a statistical model for determining availability; presents the availability conclusions for the nineteen job groups in the Professional category and the Officials and Managers category in tabular form; and discusses major issues, including an alternate statistical model. Data sources, used and not used, are appended.) (EM)
