ANCHORAGE, Alaska — The 2020 Census kicks off Tuesday in remote Alaska. U.S. Census Bureau Director Steven Dillingham will be there to conduct the first count in the Bering Sea community of Toksook Bay. Dillingham planned to spend time Friday at the Alaska Native Cultural Charter School in Anchorage, giving students a lesson on statistics. Additional outreach is planned throughout the weekend.

Why is the 2020 Census starting in Alaska?

With its sparse population and subzero temperature, rural Alaska can be hard to reach, and some of its villages are accessible only when the ground is frozen. So, the Census Bureau starts the head count in The Last Frontier state by going door-to-door in January — more than two months before the rest of the nation — so it can make sure it reaches villages before the spring thaw, when residents head out to fish and hunt. The state’s heritage is traditionally on display during these first counts. In 2000, then-U.S. Census Bureau Director Kenneth Prewitt arrived for the first count in the village of Unalakleet as a passenger in a dog sled. This year, Alaska Native dancers from Toksook Bay will perform for Dillingham.

When does it start elsewhere?

Residents in the rest of the U.S., as well as the rest of Alaska, can start responding online and by telephone in mid-March. The Census Bureau plans to send out a first round of notices explaining how to participate during the second week of March. It will send up to four more rounds of mailings, including a paper questionnaire, in March and April to households that haven’t responded.

Will someone be knocking at my door?

Only if you fail to reply online, by mail or by telephone. This is the first census in which the Census Bureau is encouraging most people to answer the questions via the internet. Around three-quarters of households will initially get invitations to respond to the questionnaire online. However, the Census Bureau realizes some communities don’t have easy access to the internet, and about a quarter of households will initially receive paper questionnaires that can be mailed back. By May, the Census Bureau will be sending out workers to knock on the doors of households it hasn’t heard back from.

What are the questions?

The form asks how many people live in the household as of April 1, whether the home is owned or rented, and the form-filler’s age, race and sex. It also asks if the form-filler is Latino, and if so, their country of origin. In the race question, the form-filler also can specify country of origin. All other residents in the household must answer, or have the first form-filler answer for them, the same questions on age, sex and race. They must specify their relationship to the form-filler and if they live elsewhere, like away at college. For the first time, same-sex couples will be able to identify as such, either as spouses or unmarried partners.

Is there a citizenship question?

No. The Trump administration tried to add the question, but the U.S. Supreme Court blocked it.

Who gets counted?

Everyone residing in the United States and the five U.S. territories, including non-citizens and immigrants living in the country illegally. Also included are military personnel temporarily deployed overseas, who are counted at their home addresses in the U.S.

Will my information be shared?

No. Under federal law, all responses are kept completely confidential, and they can be used only to produce statistics.

Why should I care?

Because it is used to determine who your representative in Congress is, where new businesses can build, how crowded your local schools will get over the next decade, and whether highways in your community get money for repairs. The results of the 2020 Census help determine the distribution of $1.5 trillion in federal spending, as well as how many congressional seats each state gets.
