Answer Details

The total population of a country can be obtained from its national census. A national census is a survey conducted by the government that aims to count every person living in the country at a specific point in time. It usually involves asking questions about demographic characteristics such as age, gender, and ethnicity, as well as household information like occupation and income. Unlike a sample survey which only captures a portion of the population, a national census is designed to be a comprehensive count of every person living in the country. It is typically conducted every 10 years and provides important information for policy-making and resource allocation. While birth rate and death rate can provide information on changes in population over time, they do not provide a direct measure of the total population.
