 No 45.8 (11) 84.6 (6465)    84.5 (6476)
  1. SD = Standard Deviation. Ever Identified as Sexual Minority in Lifetime = Ever Identified as Lesbian/Gay, Bisexual, or Mostly Heterosexual (2010).
  2. Note: The total number of cases included in each bivariate comparison differed due to missing data. The number of cases included in each comparison is indicated in parentheses.
  3. Gender Minority=Cross-Sex Identified, Transgender-Identified, and Do Not Identify as Female, Male, or Transgender.
  4. Note: Sex-specific coding was used (as determined by assigned sex at birth) when categorizing high gender nonconformity. Recalled Childhood Gender Nonconformity: % at or above top decile (score ≥ 9 for males and ≥ 12 for females); % below at or above median, below top decile (score 6-8 for males and 8-11 for females); % below median (score < 6 for males and < 8 for females). Current Socially Assigned Gender Nonconformity: % at or above top decile (score ≥ 5 for males and ≥ 6 for females).
