Every 10 years, the Constitution requires the United States to count the number of people living in the country. The census helps to direct more than $675 billion annually in federal funding. Census data is used by businesses, governments, and civic organizations to inform decision making about what services should be available in local areas. The census asks every household to answer nine questions. These questions are: how many people live in the house or apartment, whether the property is owned or rented, phone number, name, sex, and then a few questions about the age, race, and ethnicity of each person. The answers to these questions are used to help enforce anti-discrimination laws, set federal funding levels, and much more.
