Urban mortality--race or place?

Area of Science:

• Public Health
• Sociology
• Urban Studies

Background:

• Significant societal shifts in the 20th century include increased life expectancy and narrowing racial gaps.
• Economic transformation from rural to urban settings has altered residential patterns, with most Americans residing in metropolitan areas.
• Within metropolitan areas, Black populations are increasingly concentrated in inner cities, while White populations move to suburbs.

Purpose of the Study:

• To examine the relationship between urban residential patterns and Black-white mortality differences in the 20th century.
• To investigate how the proportion of Black residents in U.S. cities correlates with Black mortality rates.
• To identify the need for more granular, municipal-level data for understanding and addressing elevated Black mortality.

Main Methods:

• Analysis of national-level mortality data and trends in American society during the 20th century.
• Examination of demographic shifts, including changes in economic structure and population residential patterns.
• Comparison of Black-white mortality ratios across different city sizes (very large, medium, small).

Main Results:

• Black mortality rates are higher in large cities and appear directly related to the proportion of Black residents.
• Black-white mortality ratios are lower in medium-sized cities compared to very large or small cities.
• National-level data show associations between age-adjusted mortality ratios and causes of death, but city-specific data are limited.

Conclusions:

• Elevated Black mortality in U.S. cities is linked to urban concentration and potentially specific social conditions.
• Further research requires more detailed, municipal-level mortality data to understand and mitigate racial health disparities.
• Addressing social determinants of health is crucial for reducing mortality gaps in urban Black populations.
