Internal migration is the movement of people within the same country. It can involve moving between cities, regions, or rural and urban areas. This type of migration is common in many countries.

People may move to find jobs, housing, or better living conditions. Some travel from small towns to large cities, while others move between regions for work or education. Transportation systems such as roads and railways support these movements.

Internal migration is measured using national data and population records. It is studied in geography to understand changes within countries.
