Comparative Cluster Analysis Of Social Areas

Area of Science:

• Demography
• Urban Sociology
• Quantitative Social Science

Background:

• Demographic dimensions are crucial for understanding urban social structures.
• Previous research has isolated key demographic factors but their long-term stability is less understood.

Purpose of the Study:

• To assess the temporal and spatial stability of previously identified demographic dimensions.
• To examine the stability of social areas within communities over time.
• To validate the utility of cluster-search procedures in demographic analysis.

Main Methods:

• Cluster analysis (BC TRY System) was employed to identify demographic dimensions.
• Three demographic dimensions (socio-economic independence, family life, assimilation) were analyzed.
• Data from 33 census tract characteristics in two metropolitan areas were used, spanning a decade including World War II.

Main Results:

• The three demographic dimensions explained a significant portion of census tract characteristics.
• These dimensions demonstrated remarkable stability over the decade, persisting through World War II.
• Stability was maintained despite substantial resident turnover in the metropolitan areas.

Conclusions:

• The identified demographic dimensions exhibit high stability over time and place.
• The findings support the validity and reliability of cluster-search procedures for demographic research.
• Understanding demographic stability is key to comprehending urban social dynamics.
