Answer 1

Answer:

The correct answer is - population aging.

Explanation:

Population aging is a process of increase in the average (median) age of the population as a result of lower birth rates and an increase in the life expectancy.  

On the one hand, fewer children are born and thus fewer young people are represented in the population make-up. While on the other hand, as a result of improved healthcare and the quality of life, older people live longer which increases their number in the general population.  

Ultimately, the average age among the population increases. This phenomenon is common for the first world countries, such as Nordic countries.
