The NMS is a comprehensive national data collection focused on the museum sector. The survey captures the scope and scale of museums’ presence and reach within the United States over time. It collects data directly from museums to inform the museum field, policymakers, the public, and the media about the social, cultural, educational, and economic role that the nation’s diverse museums play in American society. 

The NMS requests high-level information about institutional characteristics, facilities, finances, human resources, admissions and visitors, and digital presence. The survey is designed to provide data that will be useful to the field while being easy for most institutions to complete.

The survey seeks to reach all museum disciplines including, but not limited to:

• Botanical Gardens, Arboretums, and Nature Centers
• Zoos and Aquariums
• Science and Technology Centers/Museums and Planetariums
• History Museums and Historic Sites
• Art Museums
• Children's Museums
• Natural History and Anthropology Museums
• General and Specialized Museums

The survey begins with a short set of screening questions to confirm whether an institution meets the criteria for inclusion such as minimum days open, at least one staff member (paid or unpaid), and provides exhibitions and programs. If your institution receives an invitation, we ask that you begin the survey and complete these initial questions so we can determine whether it should be included. Completing these questions is helpful even if your institution is ultimately determined not to be eligible, because it helps ensure that the survey accurately represents the full range of museum-related organizations in the United States. 

The NMS provides the museum field with vital and valid baseline data against which institutions can compare themselves. It also informs policies relating to federal grant funding for institutions like yours and will allow policymakers, the media, and the public to better understand the vital importance of the museum field. 

The Institute of Museum and Library Services (IMLS) is administering this survey. IMLS has authority under 20 U.S.C. 9108 to conduct data collection, analysis, evaluation, and dissemination of information to extend and improve the nation’s museum, library, and information services. The voluntary survey has been reviewed and approved by the U.S. Office of Management and Budget (OMB) under the Paperwork Reduction Act; the OMB control number is 3137-0142 and the expiration date is 11/30/2027.  

The Institute of Museum and Library Services, commonly known as IMLS, is the primary source of federal funding for the nation’s museums. The mission of IMLS is to advance, support, and empower America’s museums, libraries, and related organizations through grantmaking, research, and policy development. For additional information, please visit https://www.imls.gov/about.

The United States is home to thousands of museums that care for collections and support the cultural, economic, and social well-being of their communities through their programs and services. Prior to IMLS’s National Museum Survey effort there was no statistically reliable, freely available annual collection focused on the museum sector, especially one that reflected its full diversity—across regions, disciplines, and institution sizes. Without it, museum professionals have struggled to demonstrate the sector’s contributions to American society, and policymakers have limited insight to guide related decision-making. With input from museums leaders, researchers and other experts, over the past 10 years, the Agency has developed and tested a new approach, culminating in a 2023 pilot survey of 7,050 museums. The pilot summary report can be found at this link: NMS Pilot Summary Report. The first annual NMS was conducted in 2025 with a census of 16,426 museums; results were released in August 2026.  

The NMS stands out from other museum surveys by being the only survey of the entire museum field, covering a broad range of disciplines and ensuring that all types of museums are represented. The survey employs rigorous and transparent methods to collect data with a commitment to achieving high response rates and gathering high-quality information. As a federally sponsored, large-scale survey effort, it is distributed to over 16,000 museums nationwide. The results of the NMS are made freely available to the public providing valuable summary information. Participation in the NMS contributes to a vital tool for the museum community. 

The NMS will be conducted annually to provide the opportunity to look at trends over time and identify important topics of interest. Over time, museums may find the survey simpler to complete, as some key information will be maintained and provided for respondents in future years so that they do not need to re-enter their data.

We hope that everyone who is invited will contribute to the survey so that we can create a data source that will be used to support institutions across the United States. However, the survey is voluntary, so institutions may decline participation. Click here to request to be removed from further contacts about the NMS.  

Please use the unique link that was sent by email to your institution to complete the survey on the web. If needed, please refer to the PDF of the NMS Questionnaire to help prepare responses in advance of filling out the survey, but do not respond to the survey this way.  

If you did not receive an invitation to the survey and believe that your institution should have been invited, please contact nms@imls.gov for assistance. 

The survey asks for high-level information about institutional characteristics, facilities, finances, human resources, admissions and visitors, and digital presence. Please see the PDF of the NMS Questionnaire to help prepare responses in advance of filling out the survey. 

The NMS should take an hour or less for most institutions to complete. That hour includes the time required to refer to any records necessary to answer the questions.

The survey does not need to be completed in one session; it is designed so that it can be completed over time. The unique survey link sent to each institution can be closed and re-opened without losing a respondent’s place. This unique survey link can also be shared among colleagues within the same institution if necessary to complete specific survey sections. However, to avoid conflicting information from different users, only one person from each institution can be in the survey at a time. 

Some sections may require the primary survey respondent to work with other staff at their museum to compile answers. For this reason, the individuals who are best suited to respond to the survey are typically in administrative roles such as a CEO, executive director, head of finance, director of development, or director of communications, as they are well-positioned to coordinate quick survey completion.  

If you received the survey invitation but are not the right person at your museum to complete the survey, please forward the email to the right person in your institution and copy the NMS email address nms@imls.gov. This will allow us to reroute future messages to the correct respondent.  

The deadline for completing the survey is November 13, 2026. 

The survey data provided will be combined with those from other institutions and reported only in aggregate so that neither individuals responding nor their institution are individually identifiable. IMLS will publish reports using summary findings that will be useful to museum administrators, policymakers, the media, and the general public and data will be included in an online data portal. For more information on the data portal, see What is the National Museum data portal FAQ below. The data collected will not affect any past, current, or future relationship that individual museums or museum administrators might have with IMLS in any way.

The survey is confidential. The survey data provided will be reported only in aggregate form ensuring that neither individuals nor institutions are individually identifiable. This also means that participation and the information provided by institutions will not affect any current or future relationship they may have with IMLS.

Only the project's researchers from IMLS’s Office of Research and Evaluation and ICF have access to collected responses. IMLS’s Office of Research and Evaluation has no involvement in grant-making, and no grant-makers will have direct access to the NMS data. No one outside the research team has, or will have, access to individual survey responses.

All collected survey data will be safeguarded in password-protected files on computers and systems that meet or exceed federal security requirements. Access to the NMS’ survey platform is also password-protected and certified to meet the federal government's data security requirements. The collected data will be disposed of in compliance with all relevant federal statutes.

Survey participation will not affect any individual or institution’s current or future relationship with IMLS. Museums’ individual responses will not be available to grant-funders.

Institutions that participate will benefit by gaining access to:

• Reports on the survey’s findings
• A dynamic data portal to compare data with peer institutions’ summary results
• Comprehensive information that has never been previously available to help inform museum administrators, the public, and policymakers about the vital role that museums play in society

The data portal is a user-friendly online tool designed to view, explore, and share data from the NMS. Through the NMS Data Portal, institutions can compare their data with peer groups, benchmark performance, identify trends, support planning and data-informed decision making, and demonstrate their impact to stakeholders and funders. It helps museum professionals, researchers, and the public understand the impact of museums across the United States by providing easy access to survey results.   

Data portal visitors can look at nationwide information as well as information broken down by relevant categories such as museum type, location, and size. The portal ensures institutions’ privacy by making sure individual responses are not identifiable.  

Please contact the researchers at ICF, who are conducting the survey on behalf of IMLS, at nms@imls.gov with any specific questions you may have; someone should respond within one business day. Institutions can also use this email address to provide the name, title, and email address of the best contact for this effort.
