Census data can be used by the government for:

The correct answer is: All of the above.

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

• Planning for education and healthcare facilities: Census data can be used to identify areas with a high or low population of children or elderly people, which can help the government to plan for the appropriate number of schools and hospitals.
• Targeting welfare schemes: Census data can be used to identify people who are eligible for welfare schemes, such as those who are unemployed or have low incomes. This can help to ensure that welfare schemes are targeted at those who need them most.
• Assessing infrastructure needs: Census data can be used to assess the need for infrastructure, such as roads, bridges, and schools. This can help the government to make informed decisions about where to invest in infrastructure.

In addition to these specific purposes, census data can also be used more generally to inform government policy and planning. For example, census data can be used to track changes in population demographics, which can help the government to develop policies that are responsive to the needs of its citizens.

Overall, census data is a valuable resource that can be used by the government to improve the lives of its citizens.
