The roughly 45.6 million tourists who visited Los Angeles County in 2015 injected more than $20.6 billion into the local economy, according to a report released this week by the California Travel & Tourism Commission.

According to the report, Los Angeles County had 38.3 million domestic visitors and 23.4 million domestic overnight visitors, along with 6.8 million international visitors.

The direct spending by tourists to the area was a 4.9 percent jump from the previous year, and generated $2.5 billion in state and local tax revenue, representing 20 percent of all state tax revenue generated by tourism in the state, the report found.

The report was released in conjunction with National Travel and Tourism Week, an annual event aimed to encouraging travel.

“National Travel and Tourism Week is the perfect time to thank our local leisure and hospitality indust—our city’s ambassadors—for their everyday dedication and passion for the visitor experience that makes L.A. such a welcoming, desired destination for millions of visitors,” said Ernest Wooden Jr., president/CEO of the Los Angeles Tourism & Convention Board.
