Uneven population growth between less- and more-developed countries often leads to increased migration from less developed to more developed countries. This migration can result in several social consequences:
1. Brain Drain: Highly skilled individuals leaving less developed countries can lead to a skill shortage, hampering their development.
2. Social Tensions and Xenophobia: Increased immigration can lead to social tensions, discrimination, and xenophobia in more developed countries.
3. Overpopulation in Cities: Immigrants often migrate to cities, leading to urban overpopulation and associated issues in more developed countries.
4. Ageing Population: While migration can address an ageing population issue in more developed countries, it can leave the elderly without care in less developed ones.
5. Family Disruption: Migration often results in families being split, with profound social impacts on both sides.
These issues underscore the complex social effects of uneven population growth and the need for effective management strategies.
