RESPONDENT CONFIDENTIALITY 
In keeping with the provisions of Title 7 of the 
United States Code, no data are published that would 
disclose information about the operations of an 
individual farm or ranch. All tabulated data are 
subjected to an extensive disclosure review prior to 
publication. Any tabulated item that identifies data 
reported by a respondent or allows a respondent’s 
data to be accurately estimated or derived, was 
suppressed and coded with a ‘D’. However, the 
2012 Census of Agriculture 
USDA, National Agricultural Statistics Service 
number of farms reporting an item is not considered 
confidential information and is provided even though 
other information is withheld. 
SPECIAL EFFORTS DIRECTED AT 
MINORITIES 
NASS implemented several activities to improve 
coverage of minority farm operators. These activities 
included, but were not limited to: 
• Obtaining mail lists from organizations likely to 
contain names and addresses of minority farm 
operators; 
• Conducting pre-census promotion activities that 
targeted women, American Indian and Alaska 
Native, Black and African American, and 
Spanish, Hispanic, or Latino origin farm 
operators; 
• Special emphasis was placed on collecting data 
from individual operators on American Indian 
reservations in three States. 
SPECIAL STUDIES AND CUSTOM 
TABULATIONS 
Special studies such as the 2013 Farm and Ranch 
Irrigation Survey and the 2013 Census of 
Aquaculture are part of the census program and 
provide supplemental information to the 2012 
Census of Agriculture in the respective subject area. 
Results are published on the internet. 
Custom-designed tabulations may be developed 
when data are not published elsewhere. These 
tabulations are developed to individual user 
specifications on a cost-reimbursable basis and 
shared with the public. Quick Stats, NASS’s online 
database that allows data users to build customized 
queries, should be investigated before requesting a 
custom tabulation. 
All special studies and custom tabulations are subject 
to a thorough disclosure review prior to release to 
prevent the disclosure of any individual respondent 
data. Requests for custom tabulations can be 
submitted via the internet from the NASS home
