Class 12 Geography - CBSE
Migration Types Causes and Consequences
This Class 12 CBSE Geography chapter explores human migration, a core theme of Population Geography. It covers the types of migration including internal and international, and distinguishes between permanent, temporary, and seasonal movements. Students examine Push factors like unemployment and poverty, and Pull factors like better job opportunities and education that drive migration. The chapter further analyzes the demographic, social, economic, and environmental consequences of migration on both source and destination regions. Understanding these spatial dynamics is crucial for board exams as it bridges theoretical population concepts with real-world socio-economic patterns frequently tested through map work and analytical questions.

Place of Origin and Place of Destination
Place of origin is where the migrant moves from, which experiences a net loss in population (push factors), while the place of destination is where the migrant arrives, experiencing population growth (pull factors).
Push and Pull Factors
Push factors are negative conditions like unemployment, natural disasters, or poverty that force people to leave an area, whereas pull factors are attractive conditions like better wages, medical facilities, and peace that draw migrants to a new location.
Stream of Migration
Migration streams refer to the movement of people from specific areas of origin to specific destinations, commonly occurring between rural-to-rural, rural-to-urban, urban-to-urban, and urban-to-rural areas.
Brain Drain
An adverse economic consequence where skilled, educated professionals migrate from developing nations to developed countries, depriving the home country of essential human capital.
Demographic Consequences

Frequently Asked Questions
What is the difference between immigration and emigration?
Immigration refers to people moving into a new country (in-migration), while emigration refers to people leaving their native country to settle elsewhere (out-migration).
Why is rural-urban migration the dominant stream in developing countries like India?
Rural-urban migration is driven by push factors like lack of agricultural employment, poverty, and landlessness in villages, combined with pull factors like better job opportunities, education, and healthcare in cities.
How does migration affect the demographic profile of an urban area?
Migration usually increases the proportion of the working-age male population in urban areas, often resulting in unbalanced sex ratios and rapid, unplanned urban growth.
