How widespread are the biggest Airbnb hosts?

Ahoy! This time I come at you with a new - it’s been a while - hand-drawn dataviz.
It’s still about the current major data project I’m working on with my friend, on overtourism. In the latest editions we spoke a lot about the biggest Airbnb hosts, those that have a lot of listings, and how inequality in the ownership of listings moves in time.

This time, we looked at whether the biggest hosts of a city are present only in that city, or whether they exist elsewhere too, and to which extent. The result is:

  • this post in English

  • and its Italian version (which was written first, it’s nice to write in my own language for once)

We’re still focused on Italy for now, but we will expand the analyses to other countries soon.

There’s a few plots in the post but because some people have asked me to do a new hand-drawn one, this is the one:

A heatmap of the % of hosts that exist in each city pair, numbers range from 0.41% for Rome-Milan to 0.03% for Naples-Bologna.
Overlapping hosts means they exist in both cities.

I hope you enjoy - any comment is, as always, welcome.
