This report about undergraduate costs of attendance and financial aid in New York State is based on information provided by New York's degree-granting colleges and universities, the Higher Education Services Corporation, and a simulation model developed by New York State's Education Department. Chapter 1 compares trends in college costs, family income, and consumer prices for New York State and the nation. Chapter 2 shows trends in financial aid available to undergraduates in New York between 1980-81 and 1986-87, focusing on aid per full-time equivalent undergraduate enrollment, recipient rates and average awards, and aid applicant rates and characteristics. Chapter 3 contains two indicators of net costs of attendance: average net costs and net prices for aid recipients. Chapter 4 presents undergraduate enrollment trends for the 1980-81 through 1988-89 period. The final chapter summarizes findings and policy implications. The report concludes that college costs in New York State, like those in the nation, have been steadily rising more rapidly than consumer prices, family income, and grant aid per student during the 1980s. Twenty-four tables and 18 figures illustrate the report's findings. (JDD)
