Several measures of fertility are presented for the total population and according to socioeconomic categories: women's residence, migration status, level of education, current work status, and husband's education and occupation. Trends in fertility are examined using birth histories and data from repeat surveys in the same countries. In addition, age at first birth, parity progression ratios (PPR) and information on the length of birth intervals is examined to evaluate changes in the onset of reproduction, termination of childbearing, and spacing of births.
