Assam, a state situated in the north eastern region of India is the gateway to the region of India having
geographical area of about 78,438sq km. It shares about 2.4% of country’s landmass and providing shelter
to 2.6% of India’s population as per census of 2011. Rapid growth of population is one of the biggest
obstacle in the way of the economic development of the state. It influences various aspects of the
development of the region like social development, health, education, national income etc. Rapidly
changing pattern of the state’s population is a matter of concern in the present days. By realising the relevance of this matter. This paper highlights the trend of growth of state’s population during the post-
independence period and how the population is spreading across different religions and the possible

reasons behind such changing patterns. Tremendous inflow of migrants into the state has left it with the
massive problem of population explosion and has contributed to the changing population pattern. This work
also shows the relationship between total population and migration by estimating the marginal impact of
intrastate and international migration on total population by using the multiple linear regression model.
