I am doing a county-level analysis and I would like to use ArcMap to create some variables that describe characteristics of neighboring counties.  For example, I would like to know what the mean Percent Black is for each county???s neighboring counties.  So, if a "County A" has 3 bordering counties, 1 with 2% Black, 1 with 10% Black and 1 with 4% Black, then it would be assigned a value of 5.34 on the variable.  I would also like to create a variable that includes the highest percent Black of any bordering county.  So, in the previous example, "County A" would be assigned a value of 10. 

Does anyone know how to accomplishing this in Arc Map?  I???ve been looking over the Geostatistical Analyst tools but the closest thing I could find was the Voronoi maps option but it looks like that tool completely changes your polygons before providing descriptive statistics. 

Thank you!

We don't have anything like that in Geostatistical Analyst.  You might have more luck on the Geoprocessing forum, or maybe the ArcGIS Desktop - General forum.
