The correct answer is: All of the above.
Census data is used for a variety of purposes, including planning and policymaking, resource allocation, and delimitation of constituencies.
Planning and policymaking: Census data can be used to identify areas with specific needs, such as high poverty rates or low access to healthcare. This information can then be used to develop policies and programs to address these needs.
Resource allocation: Census data can be used to determine how to allocate resources, such as funding for schools, hospitals, and roads. This information can help to ensure that resources are distributed fairly and efficiently.
Delimitation of constituencies: Census data is used to determine the boundaries of electoral districts, or constituencies. This information is important for ensuring that all voters have an equal voice in government.
In addition to these uses, census data can also be used to track population trends, study social and economic conditions, and plan for future development.
