Census takers are responsible for collecting data from residents in order to compile a population count. They are employed by the government and typically work during the census period, which is conducted every 10 years. Census takers visit households to collect information such as age, gender, race, and other demographic information. They also provide assistance to those who need help filling out the forms. The data collected is used to determine the number of representatives each state has in Congress and to allocate federal funds.
