Socioeconomic, regional and demographic factors related to population ageing

Abstract Objective: the present study aims to investigate the association between population ageing in municipal regions in the state of Rio Grande do Norte, and socioeconomic, demographic and regional factors. Method: an ecological study that used municipal regions of the state of Rio Grande do Norte as a unit of analysis was carried out. Data collection was conducted through databases from the Brazilian Institute of Geography and Statistics, the Institute of Applied Economic Research and the Atlas of Human Development. The factor of Increased Age was created based on factor analysis, which was related to socioeconomic, demographic and regional variables. The chi-squared test with a significance level of 5% was used in addition to the Hosmer and Lemeshow technique for logistic regression. Result: it was found that municipal regions in the Central mesoregion have an older/ageing population, while those with intermediate populations have the oldest individuals. Furthermore, it was found that municipal regions with unequal income distribution and higher levels of education have an older population. Conclusion: it can be concluded that municipal regions classified as older/more aged were associated with the mesoregion to which the municipal region belongs; and those with intermediate population size were associated with favorable educational levels and unequal income distribution.
