Is the University of Wisconsin Becoming More Elite? A Partial Answer John F. Witte Barbara Wolfe Sara Dahill-Brown
Basic Theoretical Issues • Is UW-Madison Becoming More Elite in Terms of Either Applications or Admissions? • Elitism May Be In Terms of Family Income? • Or Elitism May Be In Terms of Merit? • Or It May Be a Combination of the Two
Basic Empirical Issue • Traditionally we have only poor measures of income of applicants • Self report (by 18 year olds!) • More detailed reports only for those who apply for income based financial aid
Our Approach • Match the address of applicants to Census Block data. • We have done this to date for 1972-2007 for all U.S. based applicants. • Historical data files a considerable challenge, but we have mastered "Cobol files," overwriting data entries (student addresses). • Our matching has yielded Census block matches in more than 90 percent of all applicants. • Merge these Census data with data from individual applicant records • For income in year applied, weight estimates between actual census years based on the two census estimates bracketing the targeted years. • Separate Wisconsin, Minnesota and rest of the US
