Notes:
1 Age group code = midpoint of 7-year age group range; therefore, range of ages in each age group = code +/- 3 years.
2 Participants less than 22 years of age were assigned to the youngest age group and cohort for that data collection year. In subsequent waves, these participants retained their original cohort and agegroup assignments although their actual year of birth would have placed them in younger groups.
