An establishment primarily engaged in crop production 

 (major group 01) or production of livestock and animal 

 specialties (major group 02) is classified in the four-digit 

 industry and three-digit industry group which accounts for 

 50 percent or more of the total value of sales of its 

 agricultural products. If the total value of sales of agricul- 

 tural products of an establishment is less than 50 percent 

 from a single four-digit industry, but 50 percent or more 

 from the products of two or more four-digit industries within 

 the same three-digit industry group, the establishment is 

 classified in the miscellaneous industry of that industry 

 group. Otherwise, it is classified as a general crop farm in 

 industry 0191 or a general livestock farm in industry 0291. 

 Establishments that derive 50 percent or more of the value 

 of sales from horticultural specialties of industry group 018 

 are classified in industry 0181 or 0182 according to their 

 primary activity. 



Characteristics of all farms by selected SIC groupings 

 are shown in State tables 18 and 53. The SIC groupings 

 shown in State table 53, together with the associated
