Rapid growth of population creates unemployment because:
1. Jobs are limited and if population is more then some of the people get job opportunities and rest remain unemployed.
2. Increase in population increases the burden on economic infrastructure, such as transport, communication, power, etc. which reduces the production and results in unemployment.

Or
When the work available to a worker could not utilise his labour time fully or the income received from the work is not adequate, it is known as underemployment. And this underemployment has an direct relationship with the problem of population growth. Population in India has increased at a rapid rate, but the employment opportunities have not increased to that extent due to slow pace of economic development which leads to underemployment. If rate of growth of population is controlled, then problem of underemployment can also be controlled.
