US domestic box office revenue

As Thailand has welcomed more international tourists, the American domestic box office has earned more revenue, a correlation that connects Bangkok's beaches to Hollywood's multiplexes with the cheerful confidence of a trend line that has never checked a passport. The coefficient is 0.917 across ten years, during which both industries rose, were annihilated by the pandemic, and recovered at roughly the same pace. The correlation is less about movies and beaches and more about a species that, when given the option, will reliably choose to leave the house and spend money on experiences.

Thailand tourist arrivals grew from about 25 million in 2014 to 40 million by 2019, collapsed to 430,000 in 2020, and recovered to about 28 million by 2023. US box office revenue followed a nearly identical pandemic-disrupted pattern: peaking at about 11 billion dollars in 2019, cratering in 2020, and recovering to about 9 billion by 2023. Both are in-person entertainment industries that require physical attendance and discretionary spending, and both were devastated by the same global event. The pandemic creates an artificial but powerful correlation by introducing a shared exogenous shock: when people could not gather, both industries collapsed; when they could, both recovered.

Ten years of Thai tourism and American movies moving together is fundamentally a story about people gathering in physical spaces for entertainment. The pandemic proved that both industries depend on the same thing: a world where humans are allowed and willing to show up. The tourists returned, the audiences returned, and the correlation between them is simply the resumption of normal life, measured from two different continents.
