All of the content, documentation, code and related materials made available to you through the API are subject to these terms. Access to or use of the API or its content constitutes acceptance to this Agreement.
You may use the Census Bureau API to develop a service or service to search, display, analyze, retrieve, view and otherwise "get" information from Census Bureau data.
Federal law [13 U.S.C. §§ 8 and 9] requires the Census Bureau to publish data in a manner that does not permit use of the data alone, or in combination with other available information, to identify any particular respondent to a Census Bureau survey. The identification of a person or establishment or disclosure of information collected from that person or establishment in the course of a Census Bureau survey violates the assurances of confidentiality provided by federal law.
The Census Bureau has created these data to exclude information that would directly identify respondents and characteristics that may lead to the identification of respondents. The Census Bureau provides these data to facilitate statistical research and analysis.
Therefore, users will not use these data, alone or in combination with any other Census or non-Census data, to identify any individual person, household, business or other entity; not link or combine these data with information in any other Census or non-Census dataset in a manner that identifies an individual person, household, business or other entity; not publish information from these data files, particularly in combination with any other Census or non-Census data, in a manner that identifies any individual person, household, business or other entity; and not use the identity of any person or establishment discovered inadvertently and advise the Director of the Census Bureau of any such discovery by calling the U.S. Census Bureau’s Policy Coordination Office at 301-763-6440.
All services, which utilize or access the API, should display the following notice prominently within the application: "This product uses the Census Bureau Data API but is not endorsed or certified by the Census Bureau." You may use the Census Bureau name in order to identify the source of API content subject to these rules. You may not use the Census Bureau name, or the like to imply endorsement of any product, service, or entity, not-for-profit, commercial or otherwise.
You may not modify or falsely represent content accessed through the API and still claim the source is the Census Bureau.
Your use of the API may be subject to certain limitations on access, calls, or use as set forth within this Agreement or otherwise provided by the Census Bureau. If the Census Bureau reasonably believes that you have attempted to exceed or circumvent these limits, your ability to use the API may be temporarily or permanently blocked. The Census Bureau may monitor your use of the API to improve the service or to insure compliance with this Agreement.
If you wish to terminate this Agreement, you may do so by refraining from further use of the API. The Census Bureau reserves the right (though not the obligation) to: (1) refuse to provide the API to you, if it is the Census Bureau's opinion that use violates any Census Bureau policy; or (2) terminate or deny you access to and use of all or part of the API at any time for any other reason in its sole discretion. All provisions of this Agreement, which by their nature should survive termination, shall survive termination including, without limitation, warranty disclaimers, indemnity, and limitations of liability.
The Census Bureau reserves the right, at its sole discretion, to modify or replace this Agreement, in whole or in part. Your continued use of or access to the API following posting of any changes to this Agreement constitutes acceptance of those modified terms. The Census Bureau may in the future, offer new services and/or features through the API. Such new features and/or services shall be subject to the terms and conditions of this Agreement.
The API is provided "as is" and on an "as-available" basis. The Census Bureau hereby disclaim all warranties of any kind, express or implied, including without limitation the warranties of merchantability, fitness for a particular purpose, and non-infringement. The Census Bureau makes no warranty that the API will be error free or that access thereto will be continuous or uninterrupted.
In no event will the Census Bureau be liable with respect to any subject matter of this Agreement under any contract, negligence, strict liability or other legal or equitable theory for: (1) any special, incidental, or consequential damages; (2) the cost of procurement of substitute products or services; or (3) for interruption of use or loss or corruption of data.
You agree to indemnify and hold harmless the Census Bureau, its contractors, employees, agents, and the like from and against any and all claims and expenses including attorney's fees, arising out of your use of the API, including but not limited to violation of this Agreement.
This Agreement constitutes the entire Agreement between the Census Bureau and you concerning the subject matter hereof, and may only be modified by the posting of a revised version on this page by the Census Bureau.
Any disputes arising out of this Agreement and access to or use of the API shall be governed by federal law.
The Census Bureau's failure to exercise or enforce any right or provision of this Agreement shall not constitute waiver of such right or provision.
