How Airbnb’s data hid the facts in New York City

A report by Murray Cox and Tom Slee

On December 1 2015, Airbnb made data available about its business in New York City, with much fanfare. A new report by Murray Cox and me shows that the Airbnb data release misled the media and the public.

Airbnb’s data release was presented as “the first time Airbnb has voluntarily shared city data on a wide scale on how its hosts use the online platform”. This report shows that the data was photoshopped: Airbnb ensured it would paint a flattering picture by carrying out a one-time targeted purge of over 1,000 listings in the first three weeks of November. The company then presented November 17 as a typical day in the company’s operations and mis-represented the one-time purge as a historical trend.

Key facts

  • Airbnb purged over 1,000 “Entire Home” listings from its site just days before it prepared a data snapshot of its business.
  • Airbnb used the data snapshot to paint a misleading picture of its business:
    • Airbnb’s message was that only 10% of Entire Homes listings belonged to hosts with multiple listings. The true number had been close to 19% for all of 2015.
    • Airbnb’s message was that “95% of our entire home hosts share only one listing”. The claim was true for less than two weeks of the year.
    • Airbnb’s rosy projections about the future of its business were not objective analyses based on historical trends. The company extrapolated from an artificial and unrepresentative one-time event.
  • Airbnb’s one-time purge was a PR effort, and does not indicate a change of heart for the company:
    • No similar event took place in other cities in North America or elsewhere.
    • Contrary to Airbnb projections, levels of multiple-listing entire homes have already jumped back to 13% of the total, only two months after the purge.
    • Despite claiming that it wants to “work with cities”, Airbnb carried out its purge without disclosure or consultation. Airbnb did not kick illegal hosts off the site; many commercial hosts still have listings on the site, but the purge made them appear, briefly, to be single-listing hosts.
