Brand USA reports that a study by Oxford Economics has found that in FY 2018 (1 October 2017 - 30 September 2018) marketing by the US national tourist board resulted in:

• 1.13M incremental international visits
• $4.1B in revenue for US carriers
• $1.17B in federal, state and local tax revenues
• $8.9B in US economic impact
• 52,305 incremental US jobs

And marketing ROI was 32:1.

International inbound travel accounts for 11% of all US exports, and contributes $77.4B to the national trade surplus.

Not bad. Good on Brand USA.
