What is the US Census?

The census is a national effort required by the Constitution every 10 years. We have just one chance each decade to count every person in the United States. According to the US Census Bureau, “The decennial census is the largest mobilization and operation conducted in the United States and requires years of research, planning, and development of methods and infrastructure to ensure an accurate and complete count.”
