The point made here:

A report from Travel Weekly claimed that Airbnb units account for 9% of all lodgings in major U.S. cities, and it’s increasing at a pace that is even faster than the hotel industry.

There are results calculated in 2016 here:

Providing actual source links in post gives more weight and also the authenticity to readers. That gives a lot of weight to this post.
