Census data is used for all of the above. It is used to help governments make informed decisions about how to allocate resources and develop policies. It is also used to ensure that electoral districts are fairly drawn.
Policy planning: Census data can be used to identify areas where there are particular needs, such as high levels of poverty or unemployment. This information can then be used to develop policies to address these issues.
Resource allocation: Census data can be used to determine how to allocate resources, such as schools, hospitals, and roads. This information can help to ensure that resources are distributed fairly and that they are meeting the needs of the population.
Demarcation of constituencies: Census data can be used to draw electoral districts. This information helps to ensure that electoral districts are of equal size and that they represent the diversity of the population.
In addition to these uses, census data can also be used for a variety of other purposes, such as research, marketing, and planning.
