The evolution of the old-age dependency ratio over time and its challenges in mato grosso – Brazil

Foundation: The world population is undergoing profound changes in its age distribution, impacting the labor market and health policies for the elderly. Goal: To analyze the aging trend in Mato Grosso, from 1980 to 2020 and its challenges in the labor market. Method: Time-series ecological study of the following indicators on aging in Mato Grosso: Population aging index (IEP) and Old-age dependency ratio (RDI). The source of demographic information was the Brazilian Institute of Geography and Statistics (IBGE). The Joinpoint regression method was used to analyze the temporal trend, adopting the calendar year as the regression variable. Results: The elderly population (60 years and over) in Mato Grosso grew by 182.54%, while the IEP remained stable. The RDI in both sexes significantly increased. Conclusion: Population aging in Mato Grosso happened in a similar way to other Brazilian states and European countries. However, the increase in the period’s RDI indicates the need to implement public policies through tax incentives to maintain jobs for the elderly, train them, and ensure good health conditions and quality of life, given the implementation of new technologies in the state, especially in agribusiness.
