Summary: Where you live has a significant impact on the likelihood that you will reach centenarian age, suggests a new study. New research suggests that people who live in highly walkable, mixed-age communities may be more likely to live to their 100th birthday. They also found socioeconomic status to be correlated, and an additional analysis showed that geographic clusters where the probability of reaching centenarian age is high are located in urban areas and smaller towns with higher socioeconomic status.
Based on where the person lived, the researchers used data from the American Community Survey, Environmental Protection Agency, and other sources to assign a value or score to different environmental variables for their neighborhood. The variables they looked at included poverty level, access to transit and primary care, walkability, percentage of working age population, rural-urban status, air pollution, and green space exposure. Subsequently, they conducted a survival analysis to determine which neighborhood and demographic factors were tied to a lower probability of dying before centenarian age. They found that neighborhood walkability, higher socioeconomic status, and a high percentage of working age population (a measure of age diversity) were positively correlated with reaching centenarian status. While more research is needed to expand upon their findings, the researchers said the study findings could eventually be used to create healthier communities that promote longevity in older adults.
