Americans in the first quarter of 2021 continued their 2020 pattern of moving from expensive, densely populated areas to warmer, more tax-affordable states, according to a new study from Updater Technologies.

Updater Technologies is an online platform that allows people to use a centralized hub for moving, including finding a moving company, connecting internet and utility services and updating their address. The company says the inbound and outbound data it uses is more reliable than tabulating mail forwarding forms because it captures fully completed permanent moves in real time. It also indexes cities and states based on population, since using raw numbers would skew toward the most populated areas based on sheer volume.
