Mapping global population and the future of the world

Summary

The global population is on the rise, with Africa and Asia experiencing the fastest growth, set to dominate the list of most populous countries by 2050. India is poised to surpass China, while Nigeria is on track to become the third most populous nation. Despite the benefits of a growing workforce, challenges arise with increased housing, education, and food demands. Simultaneously, Eastern Europe faces population decline due to low birth rates, high mortality, and migration, signaling a shift in global dynamics.
