Results of a spring 1983 survey of the sources and amounts of income, the expenditures, and the background characteristics of Arizona postsecondary students are presented. Survey questionnaires were sent to 4,821 randomly selected students at 36 schools, and 1,694 usable responses were obtained. The responses were cross-analyzed by four institutional categories: public universities, private colleges, community colleges, and proprietary schools. It was found that most of the respondents were 18-23 years old, but community colleges and proprietary schools had substantial proportions of older students. Only 57 percent of the community college students had received financial aid, but this percentage rose to 64 percent at the public university, to 81 percent at the proprietary school, and to a high of 88 percent at the private college. Of the aid funds, loans were most important, followed by grants and then scholarships and fellowships, Social Security, and Veterans Administration benefits. Total average expenses ranged from about $6,000 at the community college to over $11,000 at the private college. Room and board, which exceeded $3,500 for every school category, accounted for the bulk of the living expenses. A sample questionnaire is appended. (SW)
