  1. The analysis omits those addresses not successfully geocoded to both the TIGER and Parcel datasets (n = 647).
  2. * Indicates a significant (P<0.05) difference between one other geocoding method.
  3. ** Indicates a significant (P<0.05) difference between two other geocoding methods.
  4. y Indicates a significant (P<0.05) difference between housing type within the same geocoding method.
