What is Census Data?
Census data is integral to understanding societal patterns and changes in any geographical area. It provides quantitative facts about the constituents of a location - including factors like age, sex, marital status, income levels, occupation, educational attainment, housing conditions and other such information.
Census data is a primary tool used by governments and researchers for understanding the demographic structure and socio-economic conditions of a population. It serves as a basis for the development of public policies, urban planning, and allocation of resources.
The data also aids in defining electoral boundaries, determining governmental representation and equalizing public services. Businesses often use census data to decide where to open their new branches or what products might be successful in a certain demographic entity based on the collective behavior of the population.
