On Monday, October 1st, we will be changing a large amount of our U.S.
coordinate (latitude & longitude) data\* to use
[GeoNames](https://www.geonames.org/) coordinates for postal codes. This change
will ensure greater consistency during our build processes. Around 95% of US
coordinates will change with most moving about 1 mile. About 5 to 10% of US
coordinates will move by more than 10 miles.

_\* Coordinate data is approximate and is not precise. It should not be used to
identify a particular street address or household as it refers to a larger
geographical area instead of a precise location._
