    China's 1982 census data reveals significant disparities in age reporting accuracy. While generally good nationwide, Xinjiang province exhibits poor age data quality among specific ethnic groups, including the Uygur, Kirgiz, and Tajik.

    Area of Science:

    • Demography
    • Sociology
    • Public Health

    Background:

    • Accurate age data is crucial for demographic analysis and public policy.
    • China's 1982 national census aimed to provide comprehensive population statistics.
    • Regional variations in data quality can significantly impact research findings.

    Purpose of the Study:

    • To investigate the variation in age reporting accuracy in China's 1982 census data.
    • To compare the national age reporting accuracy with that of the Xinjiang Uygur Autonomous Region.
    • To identify specific ethnic groups within Xinjiang exhibiting poor age reporting.

    Main Methods:

    • Comparative analysis of census data from China and the Xinjiang Uygur Autonomous Region.
    • Examination of age heaping and age exaggeration patterns.

  • Statistical assessment of age reporting quality across different ethnic groups.

    • Main Results:

    • National age reporting in the 1982 census was generally accurate for Han Chinese and many ethnic minorities.
    • Xinjiang Uygur Autonomous Region demonstrated significant issues with age heaping and exaggeration.
    • Poor age reporting in Xinjiang was concentrated among the Uygur, Kirgiz, and Tajik populations.

    Conclusions:

    • There are substantial regional and ethnic variations in age reporting accuracy within China's census data.
    • The quality of demographic data in Xinjiang requires careful consideration due to specific ethnic group reporting issues.
    • Findings highlight the need for targeted improvements in data collection methods for diverse populations.
