Really surprised at VA being below average considering the Amazon HQ2 decision in late 2018. Of course, it could be statistical noise - @cinyc do you have at hand the VA growth estimates and the national estimates?
Amazon hasn't really begun hiring for their HQ2 campus, and while they've ramped up hiring for the AWS offices, there hasn't been the seismic impact on population the full-fledged campus will have.
The HQ2 location in Arlington isn't slated to be fully completed until Q1 2023 so it might be a while to see a noticeable effect.
