ALTERAÇÕES DEMOGRÁFICAS NO ESPAÇO MONTANHOSO DOS CÁRPATOS: UM ESTUDO DE CASO SOBRE AS MONTANHAS APUSENI (ROMÊNIA), ENTRE 1850 E 2011

Through this study we wanted to make an emphasis on demographic changes in the Apuseni Mountains, analysing the numerical evolution of the population. The period under consideration is between 1850 and 2011, and due to the high temporal gauge we decided to divide into six smaller periods. The necessary data were obtained from the consultation of population censuses and on the website of the National Institute of Statistics. Microsoft Excel 2013 was used to calculate the demographic growth and decrease values. After obtaining the values, they were processed through Geographic Information Systems (ArcGis 10.3 program), finally a series of maps were made. During the study, we found that demographic evolution was closely related to certain decisions, phenomena. Activities in the mining sector, administrative reforms and changing political regimes from socialist to capitalist were the main causes leading to demographic growth and decrease in the Apuseni Mountains from 1850-2011. Towards the end of the 20th century, the demographic component began to face risk phenomena such as the migration of the young population, demographic ageing and depopulation.
