NOTE: Personal-interest courses are defined as any courses taken in the 12 months prior to the interview that had an instructor present and were not necessarily related to a job or career. Information was collected on up to two personal-interest courses taken in the 12 months prior to the interview. If an adult took more than two courses, two were sampled for data collection. Time spent in personal-interest courses was weighted to account for the sub-sampling of courses. Details may not sum to totals because of rounding.
