When to use Primary Infecundity Percent Lookup
Use this fertility measure when the births, women at risk, parity categories, and observation period follow the definition required by the selected method.
- Infecund
- Number of women who never conceived.
- Total
- Total exposed women examined.
How the method works
- Percent
- Primary infecundity as percent of exposed women.
- Level
- Heuristic band for the observed percentage.
Limitations and assumptions
Period and cohort fertility answer different questions. Survey recall, parity truncation, changing age patterns, union definitions, and mismatched exposure populations can materially change the result.
Alternative or Complementary measures
Pair period fertility with cohort measures, parity distributions, or wanted-fertility indicators when available. These complementary views separate timing changes from completed family size and stated preferences.
