UPSC CAPF – 2021
A high wage in a potential destination is a pull factor for migration, as it attracts people seeking better economic opportunities and higher income than what is available in their current location.
Migration is often influenced by a combination of push factors and pull factors. Push factors are negative conditions or circumstances that compel people to leave a place, while pull factors are positive conditions or attractions that draw people to a place.
Natural disasters, housing shortages, and low income in the origin location are all examples of push factors, as they represent unfavorable conditions that might encourage people to leave. Pull factors contrast these by offering desirable conditions such as job availability, better services, higher education, political stability, or attractive climate.
