Population concentrations refer to areas where a large number of people live in close proximity. These regions often include urban centers, such as cities, where infrastructure, jobs, and services attract residents. High population density can lead to various social and economic dynamics, including increased demand for housing and transportation. In contrast, rural areas typically have lower population concentrations, with people spread out over larger distances. Factors influencing population distribution include geography, climate, and economic opportunities. Understanding these patterns helps in planning for resources, infrastructure, and services to meet the needs of different communities, such as cities and towns.
