For a full explanation please read the Census 2020 information located on their site.
“Students who live in off-campus housing that is not designed specifically for students – such as a rental apartment or house – need to respond to the census themselves. They should not count on their landlord to fill out a 2020 Census questionnaire. Residents of every housing unit should work together to fill out one questionnaire per household. They should include all roommates (nonstudents, too) who live and sleep in the home most of the time. The census will ask a few questions about each resident, such as age on Census Day (April 1, 2020), sex and date of birth.”
Getting funds for those resources, however, depends on making sure students are counted in the right place each census. And in most instances, if they’re not living at their parents’ home, chances are the right place is in the town where they attend school. Basically, a student’s “home” is where they currently live while attending college. “Young college students may be going off on their own for the first time, and when they see a postcard or a census worker and are asked to take the census, they may not understand that they’re supposed to take it where they’re living,” said Evan Curtis, state planning coordinator and co-chair of the Utah Complete Count Committee. “They’re not just supposed to assume that their mom or dad will fill it in for them at home.”
