The census survey will ask the name, sex, age, date of birth, race/ethnicity and relationship of everyone in your household. It will also ask if you rent or own your home. For more information on what you will be asked on the census, see the 2020 Census Website.
No, the 2020 Census will not ask a question about citizenship. The federal government has now been permanently prevented from asking the citizenship question as part of the 2020 Census in any form.
You should count anyone who is living and sleeping in your home most of the time. This includes both related family members and unrelated people, such as foster children, friends, tenants or live-in employees. For more information, see the 2020 Census Website
