How Bongaarts Proximate Determinant Index works
Multiply the Bongaarts proximate determinant indices for marriage, contraception, abortion, and postpartum infecundability. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- Combined index
- Returned number. Combined fraction of natural fertility actually realized.
Limitations and assumptions
- Definitions, sampling error, missing data, historical context, geographic boundaries, weighting, and classification choices can materially change social indicators and their interpretation.
- Marriage index must be at least 0.
- Marriage index must be no greater than 1.
- Contraception index must be at least 0.
- Contraception index must be no greater than 1.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
Report the source population and uncertainty, inspect disaggregated data, and compare multiple accepted indicators rather than treating one summary statistic as a complete social explanation.
