Comparative analysis of completed parity distributions: a global WFS perspective

Area of Science:

• Demography
• Sociology
• Public Health

Background:

• World Fertility Survey data provides insights into global fertility trends.
• Understanding completed parity distributions is crucial for demographic analysis.

Purpose of the Study:

• To analyze completed parity distributions across industrialized and developing nations.
• To investigate the relationship between fertility decline and reproductive concentration.
• To compare mean family and sibship sizes and reproductive changes.

Main Methods:

• Utilized World Fertility Survey data for ever-married women over 40.
• Employed a table-based analysis of parity by educational and residential subcategories.
• Compared mean family/sibship sizes and reproductive concentration.

Main Results:

• Fertility decline generally correlates with increased reproductive concentration (fewer women having more children).
• China represents a significant exception, showing steep fertility decline without increased concentration.
• Educational and residential factors influence parity distributions.

Conclusions:

• The transition to lower fertility often involves a shift towards more concentrated childbearing.
• China's unique demographic trajectory warrants further investigation.
• Policy implications exist for understanding diverse fertility transition patterns.
