Why We Ask Questions About...
Sex

Skip Navigation
American Community Survey (ACS)
Within About the ACS
graphical representation of the population of a community

We ask a question about the sex of each person to create statistics about males and females and to present other data, such as occupation, by sex.

Local, state, tribal, and federal agencies use data about males and females to plan and fund government programs and evaluate other government programs and policies to ensure they fairly and equitably serve the needs of both populations. These statistics also help enforce laws, regulations, and policies against 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, including companies, other federal agencies, and law enforcement.

Data about males and females help communities:

Ensure Equal Opportunity

We ask about sex in combination with information about housing, language spoken at home, employment, and education, to help government and communities enforce laws, regulations, and policies against discrimination on the basis of sex. For example, data about males and females help enforce laws against discrimination based on sex in education programs and activities receiving federal financial assistance (Title IX of the Education Amendments of 1972).

Understand Changes

Researchers, advocacy groups, and policymakers are interested in knowing whether people of different sex have the same opportunities in areas such as education, employment, and home ownership. For example, the National Science Foundation uses data by sex to provide information on women in the science and engineering workforce, and several agencies use this data to investigate whether women, including women who are military veterans, have similar employment opportunities as men.
