The official enumeration of population for a census is carried out every 10 years. This means that the government or relevant authority conducts a comprehensive count of the population in a given country or region every decade.

The purpose of a census is to gather accurate and up-to-date information about the population, which is essential for various purposes such as resource allocation, planning, policymaking, and research. By conducting a census every 10 years, governments can ensure that they have the most recent data to inform their decisions.

The decision to conduct a census every 10 years is based on several factors. Firstly, a 10-year interval allows for enough time to pass to capture significant changes in the population. This interval strikes a balance between collecting data frequently enough to stay informed and allowing enough time for population shifts to occur.

Additionally, conducting a census every 10 years is a practical approach in terms of resources and logistics. Census operations are complex and require significant planning, coordination, and financial resources. Conducting a census more frequently could be burdensome and costly for the government, while conducting it less frequently could result in outdated and less reliable data.

Furthermore, the 10-year interval aligns with other statistical practices and international standards. Many countries around the world follow a similar timeline for conducting their censuses, which allows for easier comparison and analysis of data across different regions.

In conclusion, the official enumeration of population for a census is carried out every 10 years. This interval provides accurate and up-to-date information about the population, allows for significant changes to be captured, and is practical in terms of resources and logistics.
