The uscoord.dta contains the outlines of the states. The first observations
are:
_ID _X _Y
1
1 -9618628.4 4865253.1
1 -9623409.2 4865611.5
1 -9622746.7 4854244.4
1 -9615432.3 4846464.9
1 -9627468.7 4854868.1
1 -9629634.2 4863573.2
Use the us-database.dta file to add state name or abbreviations to the map.
This file contains the centroid coordinates.
