Authority and Confidentiality

Title 13 United States Code (U.S.C.), Section 8(b); Title 50 U.S.C. Section 98, et.seq; and Title 12 U.S.C. Section 244 authorizes the Census Bureau to conduct this collection.  The U.S. Census Bureau is required by Section 9 of the same law to keep your information confidential and can use your responses only to produce statistics. The Census Bureau is not permitted to publicly release your responses in a way that could identify your business, organization, or institution.  Per the Federal Cybersecurity Enhancement Act of 2015, your data are protected from cybersecurity risks through screening of the systems that transmit your data.

This collection has been approved by the Office of Management and Budget (OMB).  The eight-digit OMB approval number is 0607-0175.   Without this approval, we could not conduct this survey.
