Reports on the public's awareness and evaluation of HUD's experimental housing allowance program in St. Joseph County, Indiana. Survey data that were collected before enrollment opened show a limited awareness of the program at that time, coupled with a favorable view among those with some information. The likelihood of knowing something about the program was greater for those with more education and higher occupational status, and for blacks and the elderly. Few thought the program would have undesirable effects, although most thought the program would affect others rather than themselves. Future analyses will shed more light on how program knowledge is diffused, who the uninformed are, and what features of the program dissuade people from applying or cause enrollees to drop out. 80 pp. Bibliog.
