We ask questions about age and date of birth to understand the size and characteristics of different age groups and to present other data by age.

Local, state, tribal, and federal agencies use age data to plan and fund government programs that provide assistance or services for specific age groups, such as children, working-age adults, women of childbearing age, or the older population. These statistics also help enforce laws, regulations, and policies against age discrimination in government programs and in society.

Your privacy concerns

We use your confidential survey answers to create statistics like those in the results below and in the full tables that contain all the data—no one is able to figure out your survey answers from the statistics we produce. The Census Bureau is legally bound to strict confidentiality requirements. Individual records are not shared with anyone, including federal agencies and law enforcement entities. By law, the Census Bureau cannot share respondents' answers with anyone—not the IRS, not the FBI, not the CIA, and not with any other government agency.
