|July 1, 1988
Summary
This study introduces iterative intracohort interpolation to estimate demographic event rates, like births and deaths, between censuses. This method refines population statistics for better demographic analysis.
Area of Science:
- Demography
- Population Studies
- Statistical Methods
Background:
- Estimating intercensal demographic rates is crucial for population analysis.
- Traditional methods may lack precision for age-specific event rates.
- Existing procedures require refinement for broader applicability.
Purpose of the Study:
- To present a generalized iterative intracohort interpolation procedure.
- To enable estimation of intercensal age-specific rates for demographic events (birth, death, marriage).
- To provide a probabilistic interpretation of estimated age-specific rates.
Main Methods:
- Iterative intracohort interpolation applied to population tabulations.
- Utilizes data on children ever born, survival, and marital status.
- Extends the original methodology developed by Ansley J. Coale.
Main Results:
- The procedure effectively estimates intercensal age schedules of event rates.
- A generalized version of the method is described.
- Probabilistic interpretations of estimated rates are provided.
Conclusions:
- Iterative intracohort interpolation offers a robust method for demographic rate estimation.
- The generalized procedure enhances demographic analysis between census periods.
- Probabilistic insights improve the understanding of age-specific demographic dynamics.
