UK Postcode Location Discrepancies

Based on OSM data from 2018‑09‑21 15:41:02 Z, there are 534 addr:postcode tags on objects with location discrepancies. The criteria are for the location in OSM to differ from the Code-Point Open centroid by more than 1000 m and more than 3 times an estimate of the unit ratius for that postal sector. Objects marked as false positives are excluded from the counts, but still appear in the tables below. To mark an object as a false positive, please contact Robert Whittaker. The data below is currently updated sporadically, probably around once a week.
