How AirROI Makes Its Tourism Statistics

We print a figure only when it passes all of these. A person or a script found the number on the page or PDF it links to. The publisher is a government, statistics office, tourism board or airport authority, so compilers and travel sites do not count. It is from 2022 or later. It is not larger than the figure for the area around it, and a jump of more than half from an earlier year goes to a person to review.

Countries mostly use UN Tourism's series of international arrivals, through Our World in Data, because it is one definition across borders. Cities and states use their own publisher, so definitions vary: some count day trips, some count only guests at registered accommodation, and some count nights. Each page gives the definition beside the figure, and our rankings only compare counts of the same kind.

Where a place has no figure of its own, its page gives the figure for the state or country around it, under that name. AirROI does not estimate tourists.

AirROI collects public Airbnb listing data every month and estimates each home's stays from it. These are estimates, not Airbnb's records, which AirROI has no access to. Each town's figures add up its homes, and each larger area adds up its towns.

Nights are stays times the typical stay, and a town's typical stay is the one its market page prints. For a town that is one multiplication. For a state or country, each town is multiplied on its own and the results added, so a resort's long stays count at their own length.

Worldwide nights. Adding up every town gives 559,835,037 Airbnb nights for the 12 months to October 2026, about 560 million. Airbnb reported 533.0 million nights and seats booked in 2025. The two cover different periods and our figure is an estimate, so read them as the same size, not as a match.

Busiest months. Against Eurostat's monthly nights for European areas, our month pattern correlates at 0.93 to 0.99, with the same peak month in 12 of the 12 areas tested. Our swing between busy and quiet months runs flatter than Eurostat's, which is why the pages lead with a rank.

A larger area's total adds the towns AirROI tracks in it, so it is a floor: homes in places we do not track are left out. Only towns whose data is current for the 12 months to October 2026 count.

Places often appear under several names: Pattaya and Pattaya City, or a Bangkok district beside Bangkok. We merge these into one row with a reviewed alias table, and a merged city's figures include its districts, so the row and the city's page show the same number. A country or state total does not change when its towns merge.

Airbnb figures refresh every month with a new 12-month period, and every page's Updated date is the day it was built. Official figures are rechecked every year in March. Each page's method note says when its figures were last checked.
