Census is the process of systematically collecting and recording information about the population of a country or region. This information typically includes demographic data such as age, gender, race, education level, income, housing, and employment status. Census data is used by governments, businesses, researchers, and policymakers for a variety of purposes, including planning public services, allocating resources, making policy decisions, and studying population trends. Censuses are typically conducted every 10 years and are important for understanding the characteristics and needs of a population.
