To predict the future population of an area, demographic transition theory can be used. This theory explains 3 staged model of demographic transition : 

The population density is the ratio between the land area and the people living over it. It is the number of people per unit of area, usually quoted ‘population per square kilometer’. The records of population census 2011 of India state that the density in 2011 has increased from a figure of 324 in 2001 to that of 382 per square kilometer in 2011.

• More people in a country always does not mean more economic trouble for the country.

According to 2011 Census, population of Mumbai was 1.84 Crore. It is India's highest populated city.

Demographic transition theory can be used to describe and predict the future population of any area. The theory tells us that population of any region changes from high births and high deaths to low births and low deaths as society progresses from rural agrarian and illiterate to urban industrial and literate society. These changes occur in stages which are collectively known as the demographic cycle. India is passing through second stage of demographic transition.
