Question

what were the causes of decrease in population in the olden days?

Answer 1

Answer:

When people move away from villages, jobs, schools, shops and other facilities also disappear. The government needs to tackle the causes and effects of population decline, for instance by cutting down on the number of new homes being built.

The size and demographics of the population change when:

fewer children are born;

families with children move to larger towns and cities;

young and better-educated people move to larger towns and cities
