The population census is an invaluable tool for national governments. It provides an accurate count of the population, along with vital socio-economic and demographic information about the population. This data is used in the development and implementation of government policies. Here are just some of the positive benefits of conducting a national census.

1. Accurately estimating population numbers: An accurate count of the population provides important information for governments to understand the size and distribution of the population, as well as the rate of population growth. This information is used to help plan for the future and allocate resources accordingly.

2. Informing government spending: With the data collected from the census, governments can better understand where their funds need to be allocated. This allows them to make better and more informed decisions on where to invest in infrastructure, services, education, and other aspects of their nations.

3. Improving access to services: The census data can provide a better understanding of the needs of people living in different areas. This allows governments to better target areas which may be lacking in services such as healthcare, education, or transport.

4. Identifying disadvantaged areas: By identifying areas where populations are disadvantaged, governments can provide targeted assistance and resources. This can help to reduce inequality and ensure that all areas of the nation are supported adequately.

5. Supporting research: The census data can provide vital information for research purposes. Researchers can use the data to gain a better understanding of trends, such as how people are transitioning from rural to urban areas, or how different areas are aging.

Overall, the population census is a valuable tool for national governments. It provides an accurate count of the population, as well as socio-economic and demographic information which can be used to support decision-making, foster equality, and inform research.
