Once again Smithsonian releases their year-end statistics, as they have since 2001.
Since the Smithsonian museums are free, visit counts are not based on tickets sold. Smithsonian guards use hand clickers to count the number of persons entering each museum. If a person visits more than one museum they will be count more than once. Therefore, the numbers shown below are considered “visits” and not individual visitors.
The question regarding “unique individual visitors” takes me the following study:, Visitors to the Smithsonian Institution Some Observations by Zahava D. Doering and Andrew J. Pekarik Instutional Studies Office Smithsonian Institution.
The following abstracts are some of the key “Observations” used to derive that calculation.
- Visitors who came to the Smithsonian from outside the local area are likely to attend several museums on the Mall during their stay in Washington and many who live in the local area will return on or more times within the same year (Doering and Bickford, 1994);
- Overall, approximately 79 percent of Smithsonian audiences consist of people who are visiting Washington from elsewhere and 60 percent are coming for the first time
