The government uses Census data for:

Designing welfare schemes
Delimitation of constituencies
Disaster preparedness
All of the above

The correct answer is: d) All of the above

Census data is used by the government for a variety of purposes, including:

  • Designing welfare schemes: Census data can be used to identify areas and groups of people who are most in need of government assistance. This information can be used to design and target welfare programs more effectively.
  • Delimitation of constituencies: Census data is used to determine the number of seats each constituency should have in the legislature. This information is used to ensure that each constituency has a roughly equal number of voters.
  • Disaster preparedness: Census data can be used to identify areas that are at risk of natural disasters. This information can be used to develop disaster preparedness plans and to target relief efforts more effectively.

In addition to these specific purposes, census data can also be used to track population trends, to study social and economic conditions, and to make decisions about public policy.
