counties reporting the data item. Counties not having the 

 item, or with a limited number of farms reporting the item, 

 have data combined and presented as "all other counties." 



ADVANCE REPORTS 



Advance reports of 1987 census data have been pub- 

 lished separately for each county with 10 farms or more, 

 each State, and the United States. This series provided, at 

 the earliest possible date, final data on major data items 

 together with comparable final data from the 1982 census. 

 Data items are standard across States except information 

 on selected crops harvested, which vary by State accord- 

 ing to their relative importance in the State. 



ELECTRONIC DATA DISSEMINATION 



The volume 1 data are available on computer tapes and 

 compact disc. The advance report data are available on 

 computer tapes, computer diskettes, and through elec- 

 tronic data services such as the AGRIDATA network, the 

 CENDATA package on Dialog, CompuServe on-line ser- 

 vices, and the Census Bureau's State Data Center Bulletin 

 Board. Computer tapes, diskettes, and compact discs are

 individual user specifications on a programming cost reim- 

 bursable basis. Inquiries about special tabulations should

 operations of an individual farm. However, the number of 



farms in a given size category or other classification, such 

 as size of farm, is not considered a release of confidential 

 information and is provided even though other information 

 is withheld.

 equipment are measured as of December 31 of the census
