Census data refers to the information collected during a census, which is a systematic count of a population. This data typically includes details about individuals such as age, gender, race, and household size. Governments and organizations use census data to understand demographic trends and allocate resources effectively. The most well-known census in the United States is conducted every ten years by the U.S. Census Bureau. This data helps inform policy decisions, funding for public services, and the drawing of electoral districts. Accurate census data is crucial for representing the needs of communities and ensuring fair distribution of resources.
