Spatio-Temporal Variation of Longevity Clusters and the Influence of Social Development Level on Lifespan in a Chinese Longevous Area (1982–2010)

Abstract: The study aims to determine the spatial and temporal variation of a longevous region and explore the correlation between longevity and socioeconomic development. Population data at the township level were obtained from the last four population censuses (1982–2010). Five main lifespan indicators and the Human Development Index (HDI) were calculated. Getis-Ord G*, Gravity modeling, and Pearson’s r between lifespan indicators and HDI were applied. In this study, a stable longevous gathering area was discovered in… Show more

“…Hechi is a relatively underdeveloped area in Guangxi and the Zhuang people comprise its main ethnicity. The Bama Yao Autonomous County of Hechi is recognized as the “hometown of longevity in the world” and has aroused widespread global interest [ 3 , 4 ]. However, other counties and cities in the Hechi area, which has six “longevity towns,” do not enjoy the same level of popularity (Bama Yao Autonomous County, Donglan County, Fengshan County, Yizhou City, Dahua Yao Autonomous County and Tiane County).…”

“…It evaluates each entity within the context of neighboring entities and compares the local situation with the overall situation (average investments). In this way, the Getis-Ord G i * statistic reveals the spatial distribution pattern and the approximate spatial aggregation range [38].…”

“…Larger proportions of centenarians tended to be located in areas of longevity in southwestern Hechi, including Bama, Donglan and Fengshan counties, especially Bama, than in other areas. However, the socio-economic index (mainly referring to the average GDP per capital) in the Hechi area was comparatively lower than that of other cities in Guangxi [ 35 , 36 ]. In addition, the socio-economic index in the longevity counties in the southwestern area of Hechi was lower than that of other non-longevity counties from 1982 to 2010.…”

“…From 1990 to 2010, Moran’s I values for the centenarian prevalence and longevity index in Hechi were greater than 0.3, with significant spatial autocorrelations. Hechi is located in a relatively remote mountainous area that is isolated from the outside world, suggesting that the natural environment has a significant impact on regional longevity [ 24 , 35 , 36 ]. Within this context, an excellent natural environment is possibly the key contributor to a large elderly population, especially regarding the distribution of centenarians, as reported by many studies on longevity [ 3 , 4 ].…”
