LIFE-M’s Temporal and Generational Structure

LIFE-M will construct intergenerational and longitudinal data. We sample birth certificate data for generation two, G2) and then link these individuals to their birth families, marriage families and children (generation three, or G3), as well as their parents’ (generation one, G1) and grandparents’ families (generation zero, G0) . The exact dates for each cohort and generation vary by state, but the approximate dates below illustrate the cohort and generational structure.
