There are issues with the synthetic population data, particularly in the Halo region, most notably the Spokane area, where the population counts are inaccurate.
These inaccuracies stem from problems in the county-level control data and the associated crosswalks.
Additionally, for counties that span multiple PUMAs, the crosswalk between counties and PUMAs is flawed, as it only draws samples from a single PUMA, leading to unrepresentative results.
