  1. a IHEs, institutions of higher education
  2. b Enrollment size based on total students enrolled for credit as reported by the Integrated Postsecondary Education Data System
  3. P value assesses whether enrollment size differs by the characteristics
  4. c The universe of 1181 private IHEs was stratified by enrollment size. Based on sample size calculations using a 95% confidence interval with a 5% margin of error, 26% of eligible private IHEs were randomly selected within each stratum (< 1000: 97 of 398 private IHEs, 1000 – 4999: 161 of 625 private IHEs, 5000 – 9999: 24 of 93 private IHEs, 10,000 – 19,999: 12 of 47 private IHEs, and ≥ 20,000: 6 of 18 private IHEs). Weights represent the inverse of the sampling fractions. n (%) represents the unweighted number (n) and the weighted percent of the universe of 547 public and 1181 private IHEs
  5. d Level of urbanization based on urban boundaries by Census GEO as reported by the Integrated Postsecondary Education Data System
