Addresses are attempted to be matched to reference geographies using different methods
associated with decreasing levels of precision in the order listed below.
Each method generates matched s2 cell identifiers differently
and is recorded in the match_method column of the returned tibble:
ref_addr: reference s2 cell from direct match to reference addresstiger_range: centroid of street-matched TIGER address ranges containing street numbertiger_street: centroid of street-matched TIGER address ranges closest to the street numbernone: unmatched using all previous approaches; return missing s2 cell identifier
Usage
addr_match_geocode(
x,
ref_addr = cagis_addr()$cagis_addr,
ref_s2,
county = "39061",
year = "2022"
)Arguments
- x
an addr vector (or character vector of address strings) to geocode
- ref_addr
an addr vector to search for matches in
- ref_s2
a s2_cell vector of locations for each ref_addr
- county
character county identifer for TIGER street range files to search for matches in
- year
character year for TIGER street range files to search for matches in
Value
a tibble with columns: addr contains x converted to an addr vector,
s2 contains the resulting geocoded s2 cells as an s2cell vector,
match_method is a factor with levels described above
Details
Performance was compared to the degauss geocoder (see /inst/compare_geocoding_to_degauss.R) using
real-world addresses in voter_addresses().
Match success rates were similar, but DeGAUSS matched about 5% more of the addresses. These differences are
sensitive to the match criteria considered for DeGAUSS (here precision of 'range' & score > 0.7 or
precision of 'street' & score > 0.55):
| addr_matched | degauss_matched | n | perc |
| TRUE | TRUE | 224714 | 92.8% |
| FALSE | TRUE | 13407 | 5.5% |
| FALSE | FALSE | 2993 | 1.2% |
| TRUE | FALSE | 1019 | 0.4% |
Among those that were geocoded by both, 97.7% were geocoded to the same census tract, and 96.6% to the same block group:
| ct_agree | bg_agree | n | s2_dist_ptiles (5th, 25th, 50th, 75th, 95th) | perc |
| TRUE | TRUE | 217179 | 14.7, 24.3, 39, 68.9, 153.6 | 96.6% |
| FALSE | FALSE | 4805 | 21.6, 39.2, 158.9, 5577.9, 16998.8 | 2.1% |
| TRUE | FALSE | 2730 | 19.6, 28.6, 41.2, 94.8, 571.8 | 1.2% |
