*New Museums—These museums have not yet been built. Congress established these museums in December 2020: the National Museum of the American Latino and the Smithsonian American Women’s History Museum. The proposed sites for the buildings are on the National Mall.

Fundraising—The Smithsonian launched a $2.5 billion campaign Sept. 13, 2024. The “Campaign for Our Shared Future” is raising funds to support four priority areas: Advancing sustainability and discovery, illuminating the nation’s past, opening pathways to new knowledge and powering creativity and innovation. All museums and research centers are part of this ambitious effort which culminates with the 250th anniversary of the United States.

Budget—The Smithsonian’s current federal appropriation is more than $1 billion. The Institution is about 62% federally funded (an annual congressional appropriation and federal grants and contracts). In addition, the Smithsonian has trust funds or non-federal funds, which include contributions from private sources (donations and endowments) and revenues from the Smithsonian Enterprises operation (magazines, e-commerce, product development, shops and cafes).

Smithsonian Collections—The total number of objects, works of art and specimens at the Smithsonian is estimated at nearly 157 million, of which nearly 148 million are scientific specimens at the National Museum of Natural History.

Smithsonian Affiliations—Through this ambitious program of long-term loans of collections of artifacts and the expertise of its staff, the Smithsonian shares its vast collection and programmatic resources with museums and educational institutions around the country. There are more than 200 affiliates in nearly every state, Puerto Rico and Panama. For more information, visit www.affiliations.si.edu.

Traveling Exhibitions—The Smithsonian Institution Traveling Exhibition Service (SITES) organizes exhibitions on art, history and science and circulates them around the country. Each year, SITES travels more than 40 exhibitions to hundreds of U.S. cities and towns in all 50 states and the District of Columbia, where they are viewed by millions of people.

Research Facilities—These include the Archives of American Art, Smithsonian Conservation Biology Institute, Smithsonian Astrophysical Observatory, Smithsonian Environmental Research Center, Museum Conservation Institute, Smithsonian Libraries and Archives, Smithsonian Tropical Research Institute and the Marine Station at Fort Pierce, Florida.

Digital—The Smithsonian home page, www.si.edu, offers a wide range of information, from planning a visit to exploring the collections online.  Also, the Smithsonian had 150 million unique visitors to its website in 2024, and has more than 30 mobile apps, digital magazines and more than 17 million images and records on the Collections Search Center site. Across its most frequently used social media platforms, Instagram, Facebook, YouTube, LinkedIn and X (previously Twitter), the Smithsonian had more than 17 million followers and 81 million video views in 2024.

History—Established with funds from James Smithson (1765–1829), a British scientist who left his estate to the United States to found “at Washington, under the name of the Smithsonian Institution, an establishment for the increase and diffusion of knowledge.”
