In a new report, the company noted that these so-called “emerging markets” currently make up its 25 fastest-growing countries for guest arrivals.

Currently, more than 30% of listings on the site are in those regions. By 2030, they expect that more than 400 million users will have checked into an Airbnb in an emerging market since 2008.
