Americans don't have hukou. How to count population migration?

Yes, there is no household registration system in the United States. Americans have no household registration, and there are no police stations, village committees, neighborhood committees and other management institutions. Every time American citizens move to a new place, they automatically become residents there, have the right to manage the local government-the right to vote and other political participation, and automatically enjoy local social welfare benefits. No application, no approval, no household registration procedures.

Every time American citizens move to a new place, they automatically become residents there, have the right to manage the local government-the right to vote and other political participation, and automatically enjoy local social welfare benefits. No application, no approval, no household registration procedures. As long as you live in that place, even if you rent a house, the local government will take the initiative to find you and let you exercise your rights. Such as voter registration, jury candidate registration and so on. During the election, the candidate's campaign team will take the initiative to send you campaign materials to seek your support and "management".

Governments at all levels in the United States obtain citizen information from DMV (Motor Vehicle Department). In America, almost all citizens have driver's licenses. According to the American driver's license regulations, drivers must register with the vehicle management office every time they go to a place for more than 15 days, otherwise they will be regarded as driving with invalid documents. Therefore, every citizen who moves will go to the vehicle management office to register the information about the change of residence. In this way, the vehicle management office will have detailed inflow and outflow information of people with driver's licenses, and the local government will also get inflow and outflow information of local residents.

In America, a driver's license is an ID card. You have to show your driver's license when you fly in a domestic plane, show your driver's license when you stay in a hotel, and show your driver's license wherever you need identification.

People who don't have a driver's license, such as disabled people who have never driven a car, or elderly people who have recently immigrated, will apply for ID cards. I also go to the DMV to get my ID card. When you apply for an ID card in a motor vehicle, the ID card looks the same as a driver's license.

Another channel for the US government to know citizens' information is the social security records of residents. All legal residents in the United States have social security cards, and the social security number (also translated as social security number) is unique.
