Concept:
Population growth refers to the increase in the number of people living in a particular area, while migration refers to the movement of people from one place to another. Migration plays an important role in influencing the size and distribution of population.
Step 1:Migration as a factor of population change.
Population growth in a region depends not only on birth and death rates but also on migration. When people move into an area (immigration), the population increases, while when people move out (emigration), the population decreases.
Step 2:Impact on urban population growth.
Migration from rural areas to urban areas leads to rapid population growth in cities. People often migrate in search of employment, education, and better living conditions.
Step 3:Redistribution of population.
Migration redistributes population from densely populated regions to less populated areas or from rural regions to urban centers, affecting regional population patterns.
Step 4:Economic and social effects.
Migration can contribute to economic development by providing labor in industries and services. However, excessive migration can also create challenges such as overcrowding and pressure on urban resources.
