Human Migration, Culture, and Population

People are always on the move, carrying their ways of life with them and reshaping the places they leave and the places they arrive. The study of human migration, culture, and population explains how the human map of the world came to look the way it does — and it rounds out the geography section of the test.

Migration is the movement of people from one place to another to live. Culture is the shared way of life of a group — its language, religion, food, and customs. Population is the number of people living in an area and how they are distributed.

Why People Migrate

Geographers explain migration with push and pull factors. Push factors drive people away from a place — war, poverty, natural disasters, lack of jobs, or persecution. Pull factors draw people toward a new place — jobs, safety, freedom, family, or better living conditions. Most migration is a mix of both: something pushing people out and something pulling them somewhere new. This framework explains everything from immigration to the United States to movement within a country.

Culture and Cultural Diffusion

When people move, they bring their culture with them, and cultures blend and spread. The spread of cultural features — foods, languages, religions, technologies — from one place to another is called cultural diffusion. Migration, trade, and now the internet all spread culture. This is why you can find pizza, hip-hop, or a particular religion far from where it began. The United States, shaped by waves of immigration, is often described as a cultural blend for exactly this reason.

Population Patterns

People are not spread evenly across the earth. Population density — how many people live in a given area — is high in cities and low in deserts or mountains, because geography and resources shape where people can thrive. Urbanization is the growing share of people living in cities, a major worldwide trend. Studying population helps explain pressures on resources, the environment, and government services. When a question shows a population map or chart, look for where people cluster and why.

A Routine for Migration and Population Questions

1. Push factors drive people away; pull factors draw them in.
2. Migrants carry culture, leading to cultural diffusion and blending.
3. Population density is high in cities, low in harsh environments.
4. Urbanization is the shift of people from rural areas to cities.
