For reference, the 2024 numbers:
Domestic Leisure: $876 billion
Domestic business: $312 billion
International inbound: $181 billion
That seems to show that in 2024, international visitor spending in the USA accounted for about 13% of a $1.37 trillion tourism industry. So an overall drop of about 7% in international spending would represent about a 1% overall drop in total tourist spending.
Certainly not devastating, but as others have pointed out, some areas of the country will be impacted more than others. And those numbers are from May and the numbers continue to fall. Many first and second quarter trips may have been prepaid or had heavy cancellation policies. It will be interesting to see what plays out over the next year.
The CPA in me wonders how they gather those figures and what is included in them? If they include things like hotels, restaurants, and car rentals, how do they distinguish between domestic and international spending? Does it include things like shopping or groceries? Could it possibly understate the impact of international travellers?
For example, when I travel in the USA I have a US-issued debit and credit card on a US bank account that is linked to my Canadian banking. When I pay for something in the US with those cards or with cash, how do they tell whether it is domestic or international spending? I doubt anyone really knows the answer, but I would love to find out if anyone does.
As my university ECON 201 prof was fond of saying, "You can prove just about anything you want with statistics. It is important to understand the context, inclusions, and shortcomings of the data." And of course, there is the old maxim, "There are three kinds of lies: lies, damned lies, and statistics."
Finally, much of the tourism industry tends to be more labour-intensive than many other sectors. So any drop in tourism spending, whether domestic or international, could also have a larger impact on unemployment statistics.
As for myself, I have done more domestic travelling this year, have visited the Caribbean, will be doing a trip to the UK in late September, and switched my normal three-week timeshare stay in November in South Carolina to Cabo San Lucas.
