Tourism in numbers · Falls × airport
Two official, open sources measure the same tourism economy: visitation to Iguaçu National Park (ICMBio) and passenger movement at Foz do Iguaçu airport (ANAC). They move side by side — the ratio stays steady near 0.91 Falls entry per airport passenger. That makes the airport, released every month, a leading indicator of visitation, which is only published months later.

The coupling ratio
Across full years, for every passenger through the airport there are about 0.91 Falls entries — and that ratio barely changes year to year. When the airport rises, visitation rises with it. Because ANAC data is monthly and public while the ICMBio count lags by months, the airport becomes the thermometer that anticipates the season.

Falls BR × AR
Iguaçu National Park (BR) and Iguazú National Park (AR) sell tickets to the same falls — and we are the only ones crossing the two official counts. In years with data from both sides, the Brazilian side receives on average 1.1× the Argentine side's crowd. The Argentine series holds 217 months (since 2008, datos.gob.ar).
| · | BR side | AR side | BR/AR ratio |
|---|---|---|---|
| 2019 | 2,020,358 | 1,859,676 | 1.09 |
| 2021 | 655,335 | 676,974 | 0.97 |
| 2022 | 1,434,308 | 1,728,425 | 0.83 |
| 2023 | 1,833,398 | 1,840,589 | 1.00 |
| 2024 | 1,893,116 | 1,479,567 | 1.28 |
| 2025 | 2,058,539 | 1,761,664 | 1.17 |
The Argentine park peaks in January; the Brazilian side peaks in July. In July hotels fill up on both sides of the border, yet the winter crowd visits the BR side more — same falls, two calendars. That is why we measure city and attraction separately.

Plane × bus · the two measured gateways
Adding airport and bus terminal since 2019, about 33% of arrivals come by bus — a share that stays stable all year. The bus share peaks in December (34.4%), the holiday-season month: the bus is the family-visit modal. In July both gateways rise together — winter's extra road traffic (charter buses and cars) doesn't pass through a measured gateway.
| month | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| % by bus | 32.2% | 32.2% | 32.2% | 33% | 32.1% | 32.3% | 32.1% | 29.3% | 30.1% | 29.1% | 29.9% | 34.4% |
Honesty: the terminal counts scheduled lines only; charter buses and private cars (23% of demand, 2024/25 survey) don't pass through the measured gateways. This is a portrait of the TWO gateways, not of every visitor.

Honesty of the numbers
ANAC passengers count movements (boarding + landing), not people, and many Falls visitors arrive by land — buses from Ciudad del Este, Argentine day-trippers, cars. So the ratio is a coupling index between two demand signals, not the share of flyers who visit the Falls. What it shows, robustly, is that the two rise and fall together.
Official, open sources
Why this is ours
There is no API that returns the Falls' occupancy. We built our own model by crossing official, open sources — and a turnstile or entrance camera, via partnership, gives the fine hour-by-hour truth. It's the model replicable to any destination in Brazil.
