The census is a counting system for the government to count people so they can adjust how much stuff is needed in places. It impacts what is all in places and in a time like now, it can bring food drives closer to people and kids in a area. Also if there is more kids in a area, the government might give the schools money to support all of the kids. It can also bring more medical supplies to a place where there was not before for the people there.
Those are some of the ways the census helps people and there is more that I can’t think of. So that’s why you should fill out the census.
