As the Georgia Aquarium celebrates its tenth anniversary, a new economic impact study finds the museum has injected $1.9 billion in the local economy in the last decade.

According to a new report by Bleakly Advisory Group, since opening the Aquarium has attracted some 22 million visitors, from which a majority hailed out of state, and contributed $8.1 million annually in state and local sales taxes in the last year.

“Every dollar invested in Georgia Aquarium generates an additional $2.50 of private and public investment to the area,” chief operating officer Joe Handy told the Atlanta Business Chronicle.

Already the largest aquarium in North America, the facility is slated to open a new $40 million California sea lion exhibit next month, with later expansions for an expanded dolphin exhibit underway as well.
