We have improved our address matching procedure and will be releasing a new version of HUDADMIN soon. If you contact me at david.a.vandenbroucke@hud.gov, I can send you a skinny file with the improved variable, which shows fewer mismatches than the version in the current PUF.
The AHS sample includes an oversample of addresses drawn from HUD administrative records (and thus known to be assisted). The oversample cases are identified by HUDSAMP=1. If you crosstabulate your results with HUDSAMP, you will see that almost all of the mismatched cases are from the general sample, not the oversample. This is evidence that the address matching process still needs work. The weighted results are more skewed than the unweighted because general sample cases have higher weights than oversample.
