²: SES is based on the Hollingshead’s nine-step scale used by Achenbach (1991) to rate SES based on parent occupation. We make no assumption about the validity of the Hollingshead scale for non-U.S. cultures. Our purpose here was to assess differences in parent occupation across the two national samples, which required that we use the same rating system used previously for U.S. CBCL samples.

³: Gender is percent male.
