The Monterey Bay Aquarium, founded in 1984, is situated on the beautiful coast of Monterey Bay in the historic Cannery Row district. In 1985, the aquarium began a survey program that involved randomly sampling visitors as they exit for the day. The survey included visitor demographic information, use of social media, and opinions on their aquarium visit. For each visitor sampled during 2013-2015, the distribution of the number of children in their group is given.
