Which of the following contribute to the shrinking population in Europe

1. Low birth rates: Many countries in Europe have low birth rates, with women having fewer children or choosing not to have children at all. This leads to a smaller population size over time.

2. Aging population: Europe has an aging population, with a growing number of elderly individuals and a smaller number of younger people. This can lead to a decrease in the overall population size as there are fewer people of reproductive age.

3. Declining fertility rates: Fertility rates in Europe have been declining over the years, with fewer women having children. This contributes to the overall shrinking population.

4. Economic factors: Economic instability and high costs of living in many European countries can deter individuals from having children or starting families, thus leading to a smaller population size.

5. Migration: Emigration of people from Europe to other countries for better opportunities or quality of life can also contribute to a shrinking population in the region.
