Birth timing  (BIRTH timing)


Studies of birth timing 1 deal with the length of birth intervals 2. These include the interval between marriage and the first birth 3 and intervals between successive births 4. The interval between a birth and a fixed date, such as that of a census (202-1 *) or survey (203-4), is called an open birth interval 5; intervals that begin before and end after that date are called straddling intervals 6. The interval between marriage and the Nth birth 7 is also used to study the timing of births.

  • 1. Birth spacing, although sometimes found in the sense of birth timing as above, is commonly used to refer to the deliberate efforts of couples to postpone a birth.
  • 3. Also called first birth intervals. The second birth interval is that between the first and the second birth; and so on.
  • 4. As seen from the vantage of that census or survey, the intervals between the recorded successive births are called closed birth intervals.
