The United Nations predicts that the global population will reach 9.7 billion by 2050, and further increase to 10.4 billion by 2100. This growth is driven partly by declining death rates and an increase in average life expectancy. However, some regions, particularly in Europe, are facing population declines due to lower birth rates and a trend towards smaller families. It's projected that by 2050 the populations of 61 countries or areas will decrease by at least 1%, largely due to low fertility and also high emigration rates.
