The geocoding error rate gives us an idea of how accurately the MAF places an address in the correct geographic area. The pooled Non Harris areas were not significant, but are shown for information. Again, only Harris is significant, and it is not significantly different from any other area. The Non Harris rate is shown for information. The HU and BSA geocoding error rates presented here are promising, though they do underrepresent the true rates.
More research needs to be done to evaluate and improve the geocoding process.
The geocoding operation is important in that it places a housing unit or basic address in the correct tract and block, allowing the Census Bureau to collect, control, and tabulate data by geographic area. It is difficult to speculate how different any of our results would have been if our study had included areas with noncity-style addresses. The matching process certainly would have been more difficult. The coverage provided with these noncity-style addresses will need to be evaluated in future tests and studies. Previous research .
