The correct answer is: Internal migration.
Internal migration is the movement of people within a country’s borders. It can be either rural-to-urban migration, urban-to-rural migration, or migration between two urban areas.
Rural-to-urban migration is the movement of people from rural areas to urban areas. This type of migration is often driven by economic factors, such as the search for better job opportunities.
Urban-to-rural migration is the movement of people from urban areas to rural areas. This type of migration is often driven by a desire for a better quality of life, such as a slower pace of life or a closer connection to nature.
Migration between two urban areas is the movement of people from one urban area to another. This type of migration is often driven by economic factors, such as the search for better job opportunities.
Commuting is the daily movement of people between their homes and their workplaces. It is a form of short-distance migration.
In the case of Goa, the migration of people from rural areas to urban centers is a form of internal migration. This is because the people who are migrating are moving within the borders of India. The migration is likely being driven by economic factors, such as the search for better job opportunities.
