Summary
This study questions the reliability of Turkey's 1990 census sex ratios. Researchers reconstructed the population using birth rates and survival rates to improve demographic accuracy.
Area of Science:
- Demography
- Population Studies
- Statistical Analysis
Context:
- The 1990 Turkish Census data exhibits potential inaccuracies, particularly concerning age-specific sex ratios.
- Existing census and survey data may not reliably reflect the true demographic structure.
Purpose:
- To evaluate the reliability of age-specific sex ratios in the 1990 Turkish Census.
- To derive accurate sex ratios at birth using multiple data sources.
- To reconstruct the 1990 Turkish population by surviving birth cohorts.
Summary:
- The study identifies errors in Turkish census and survey data, questioning the reliability of age-specific sex ratios from the 1990 Census.
- Sex ratios at birth were calculated using census, survey, and hospital records.
- Population reconstruction involved applying historical birth rate trends and cohort-specific survival rates from the Coale-Demeny Model Life Tables.
Impact:
- Provides a more accurate demographic profile of Turkey for the year 1990.
- Highlights the importance of data validation and cross-referencing in demographic research.
- Offers a methodology for population reconstruction in contexts with data quality issues.
