  1. MVPA = moderate to vigorous physical activity.
  2. B = unstandardized regression coefficient.
  3. CI = confidence interval.
  4. ICC = intraclass correlation coefficient assessing proportion of variance between block groups.
  5. M = model number.
  6. aControlling for age, ethnicity, gender, education, marital status, months at address, number of people in the household and number of vehicles per adult.
  7. bICCs are for the empty model containing no independent variables.
  8. *Significant at p < 0.05.
