Information on the costs of attending different types of postsecondary institutions are presented in 18 tables showing average expenses for resident students, both those living in campus housing and those in private housing, commuting students, and self-supporting students. Also presented are data showing how postsecondary educational expenses are increasing and how expenses vary by region. Some findings are: (1)-the overall increase in total expenses for resident students at all types of institutions from 1975-76 to 1976-77 averages about 8 percent; (2)-total expenses rose 8 percent for resident students at public institutions and 6 percent for resident students at private institutions from 1975-76 to 1976-77; (3)-the difference in total expenses for resident and commuter students is approximately $500; (4)-the difference in the tuition and fees between private and public institutions is $1,353 for the two-year institution and $1,708 for the four-year institution; and (5)-total expenses minus tuition and fees vary only slightly by institutional type and control.
