Human populations are distributed based on factors such as fertility, mortality, migration, economic development, industrialization, and climate change.
Step-by-step explanation:
Human populations are distributed based on several factors including fertility, mortality, and migration. The distribution of human populations is influenced by economic development, industrialization, job opportunities, and access to education. Climate change also plays a role in population distribution as it can force people to relocate from certain regions. Additionally, there is a correlation between income and urbanization, with higher income countries having a higher percentage of urban population.
