The correct answer is: a) Rural to urban migration.
Mizoram is a state in northeastern India. It is the second least populous state in India, with a population of just over 1.1 million people. The majority of the population of Mizoram is rural, with only about 20% of the population living in urban areas. However, in recent years, there has been a significant increase in rural to urban migration in Mizoram. This is due to a number of factors,
including the lack of economic opportunities in rural areas, the desire for better education and healthcare, and the pull of urban centers like Aizawl and Lunglei.The large-scale influx of people from other states is not a major pattern of migration in Mizoram. The state has a relatively small population, and the majority of the population is indigenous to Mizoram. There is some migration from other states, but it is not on a large scale.
Significant emigration to foreign countries is also not a major pattern of migration in Mizoram. There is some emigration, but it is not on a large scale. The majority of the population of Mizoram remains in the state.
Seasonal migration of nomadic tribes is not a major pattern of migration in Mizoram. There are some nomadic tribes in Mizoram, but they are a small minority of the population. The majority of the population of Mizoram is not nomadic.
