This SAS/Graph Procedure should work:
Overview: GINSIDE Procedure
The GINSIDE procedure compares a data set of X and Y coordinates to a
map data set containing map polygons. The procedure determines whether
the X and Y coordinates for each point fall inside or outside of the map
polygons. If the point falls inside a polygon, then the ID variable is
set to the ID value of that polygon. For example, if a map contains
states, then the ID variable of the output data set is set to the state
that contains the point. The GINSIDE procedure can be used with the
SAS/GRAPH map data sets and the results can be used to annotate onto a
map with the GMAP procedure.
Note: Avoid unpredictable map results with points that fall on the
border of a polygon by using the INCLUDEBORDER option. This option
includes points that are on the border of a polygon in the output data
set. These points are identified by the variable named _ONBORDER_ with a
value of 1.
