Summary
US age segregation has decreased significantly from 1990 to 2010, contrary to prior research. This trend was observed nationally, by state, and by county, impacting health and wellbeing.
Area of Science:
- Gerontology
- Sociology
- Urban Studies
Background:
- Age segregation negatively affects health and wellbeing.
- Previous studies indicated rising age segregation in the US but were limited in scope and methodology.
- There is a need for comprehensive analysis of spatiotemporal patterns and correlates of intergenerational segregation.
Purpose of the Study:
- To assess spatiotemporal patterns of age segregation in the US from 1990 to 2010.
- To identify factors associated with adult-older adult segregation across US counties.
- To provide updated evidence contradicting previous findings on age segregation trends.
Main Methods:
- Utilized US census-tract data from 1990 and 2010.
- Computed the dissimilarity index (D) at national, state, and county levels to measure age segregation.
- Employed regression analyses to examine correlates of adult-older adult segregation.
Main Results:
- Demonstrated a robust decrease in age segregation across most of the US.
- Observed declining age segregation at national, state, and county levels.
- Found that rurality was associated with lower segregation, though this diminished over time; higher percentages of older adults and group quarters populations were inversely related to segregation.
Conclusions:
- US age segregation has generally decreased between 1990 and 2010.
- Factors influencing age segregation have shifted compared to previous decades.
- The findings necessitate a re-evaluation of policies and interventions related to age-integrated communities and their impact on population health.

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...

Culture shapes how people approach attraction, choose partners, and build long-term relationships. While some preferences in mate selection appear consistent across cultures, such as men valuing physical attractiveness and women emphasizing financial resources, cultural contexts influence how these preferences are expressed and prioritized. Marriage extends beyond romantic ideals in many societies and is deeply embedded in social, economic, and religious frameworks.The Role of Culture in Mate...

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
