The 2020 count will be the first one to allow all U.S. households to respond online. Paper forms will still be available, and, for the first time, you can call 1-800 numbers to give responses over the phone. Census workers will make home visits to remote areas — including rural Alaska, parts of northern Maine and some American Indian reservations — to gather census information in person. Households in the rest of the U.S. that do not respond themselves by early April may start receiving visits from door knockers trained to conduct census interviews and collect responses using smartphones.
