  • Examination of health records for mothers and children in relation to family size.

    • Main Results:

    • Larger families exhibit more rigid child-rearing, less individualization, and increased corporal punishment.
    • Children from smaller families tend to have higher IQ, academic achievement, and occupational performance.
    • Increased rates of delinquency, alcoholism, lower birth weights, higher perinatal morbidity/mortality, and maternal disease risk are associated with larger families.

    Conclusions:

    • Family size significantly impacts child cognitive and behavioral development.
    • Larger family size poses risks to both child health and maternal well-being.
    • Methodological rigor is crucial when studying the effects of family size.
