The regularity of migration patterns often depends on factors like proximity to resources, economic opportunities, and living conditions. For instance, rural areas, which may lack the infrastructure needed to support large populations, can drive people to migrate to urban centers. These migrations are also influenced by fertility rates, as families in rural areas might have more children but face limited access to education, healthcare, and job opportunities, further encouraging movement to cities. In contrast, urbanization tends to increase as cities offer better infrastructure, including transportation, education, and employment, drawing in individuals from less developed regions.
