The remaining residential addresses in that ZIP So, for example, if one wanted to allocate data from ZIP code to each Census tract located in that ZIP code, one would multiply the number of observations in the ZIP code by the residential ratio for each tract associated with that ZIP code.

Since the HUD geocoding base map is updated regularly, an effort is made to re-geocode these records with every new quarter of data. As a result, these crosswalk files will be generated on a quarterly basis and may differ slightly from quarter to quarter.

For example, we aim to publish fourth quarter by the end of January, first quarter by the end of April, and so on.
