Notes: Expanded sample sizes are numbers of person-year observations. Each cell in the table corresponds to a separate data set, for which the sample size (number of person-year observations) is shown. There are 96 data sets. For each data set, weighted and unweighted sample sizes are the same. B–M denotes the transition from a woman’s own birth to first marriage, and M–1 denotes the transition from first marriage to first birth. In the period analysis, periods are the five-year period before each survey. In the cohort analysis, cohorts are defined as women aged 40–49 at the time of the survey. The B–M expanded sample size for the 2003 period analysis is relatively small because the B-M period life table starts at age 12 instead of age 10 as a consequence of empty-cell problems at ages 10 and 11.
