The Decennial Census is a nationwide survey conducted every ten years in the United States. It aims to count every person living in the country, providing essential data for government representation and resource allocation. The results help determine the number of seats each state has in the U.S. House of Representatives and guide the distribution of federal funds. The census collects information on various demographic factors, including age, race, and household size. This data is crucial for local, state, and federal governments, as it informs policy decisions and helps communities plan for services like schools, roads, and healthcare.
