1/ Twenty-percent classes are used to indicate relative 

 changes, since sampling errors preclude the use of direct 

 comparisons for county volumes. 



2/ Because of sampling errors, small volumes, and defini- 

 tion differences, comparisons in volume for individual counties 

 in the Southeastern Unit and the Western Unit (which includes 

 the Red River Valley and the southwestern counties) are not 

 statistically meaningful.
