Abstract
Se estimó y analizó la dinámica socio-demográfica de la población en la Reserva de Biosfera Nevados de Chillán – Laguna del Laja, a partir de los datos del Instituto Nacional de Estadísticas (INE) obtenidos en los censos de población 2002 y 2017. Se sintetizó la información de edades en grupos quinquenales para los distritos pertenecientes a la reserva en el área de la región de Ñuble. Los resultados arrojaron una población total de 13.864 personas en 2002, que disminuyó a 12.662 personas en 2017. Al analizar el crecimiento poblacional durante este periodo, se observó una tasa de crecimiento geométrica negativa del 0,006%. Además, se calculó el Índice de Envejecimiento (IE), el cual mostró un aumento de promedio significativo del 8,3% en 2002 al 16,3% en 2017. Por otro lado, el Índice de Dependencia Demográfica (IDD) experimentó una disminución, pasando de un promedio del 57,2% en 2002 a un 50,8% en 2017. Se elaboraron mapas cartográficos que representan visualmente la dinámica poblacional en tres grupos de edades, así como cartografías que muestran los índices calculados por distrito censal.
The socio-demographic dynamics of the population in the Nevados de Chillán – Laguna del Laja Biosphere Reserve were estimated and analyzed, based on data from the National Institute of Statistics (INE) obtained in the 2002 and 2017 population censuses. age information in five-year groups for the districts belonging to the reserve in the Ñuble region area. The results showed a total population of 13,864 people in 2002, which decreased to 12,662 people in 2017. When analyzing population growth during this period, a negative geometric growth rate of 0.006% was observed. In addition, the Aging Index (IE) was calculated, which showed a significant average increase from 8.3% in 2002 to 16.3% in 2017. On the other hand, the Demographic Dependency Index (DID) experienced a decrease , going from an average of 57.2% in 2002 to 50.8% in 2017. Cartographic maps were prepared that visually represent the population dynamics in three age groups, as well as cartographies that show the indices calculated by census district.
