Answer:
The correct answer is - <em>population aging.</em>
Explanation:
<u>Population aging</u> <u>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.</u>
On the one hand, <em>fewer children are born</em> 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, <em>older people live longer</em> 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.
