The correct answer is: b) Population Enumeration
Population Enumeration is the main phase of the Census where detailed socio-economic data is collected. It is the process of counting the population and collecting information about their characteristics, such as age, sex, race, ethnicity, and housing.
Houselisting is the process of identifying and locating all households in a geographic area. This is done before the Population Enumeration phase, so that enumerators can visit each household and collect data.
Post-Enumeration Survey is a survey that is conducted after the Population Enumeration phase. It is used to collect additional information about the population, such as income, employment, and education.
Data Processing is the process of cleaning, editing, and tabulating the data collected during the Population Enumeration phase. This data is then used to produce the Census report.
