Census data reveals that Assam has a:

Relatively young population
High dependency ratio
Declining population
Rapidly aging population

The correct answer is: a) Relatively young population.

Assam has a relatively young population, with a median age of 27.2 years. This is significantly lower than the national median age of 28.5 years. The state’s population is also growing at a faster rate than the national average, with an annual growth rate of 1.4%. This is due to a high fertility rate and a low mortality rate.

A young population has a number of advantages. It can lead to a more dynamic and innovative economy, as well as a more vibrant culture. However, it also poses some challenges, such as a need for more education and employment opportunities.

A high dependency ratio is a situation in which there are more people of working age than there are people of non-working age. This can put a strain on the economy, as there are fewer people to support the working population.

A declining population is a situation in which the number of people in a country or region is decreasing. This can be due to a number of factors, such as low birth rates, high death rates, or emigration.

A rapidly aging population is a situation in which the proportion of people aged 65 and over is increasing. This can put a strain on the economy, as there are fewer people of working age to support the elderly population.
