  1. 1 National Longitudinal Study of Adolescent Health, Wave I (1995-96), n = 18,294. Obtained from exploratory factor analysis using a principal factors estimator and oblique oblimin (gamma = 0) rotation. Unweighted correlations with non-diverse landscape were -0.03 and -0.02 for intensity (pay facilities) and intensity (public facilities), respectively; and 0.58 between intensity (pay facilities) and intensity (public facilities).
  2. 2 Indicator variable(s) used to represent corresponding factor in Tables 8 & 9.
  3. --For clarity, loadings with absolute value <0.2 were omitted
