Here’s a quick observation that may or may not be generalizable.
All three of our AirBNB hosts have been women. One appears to be somewhat artistic or design oriented (based on her clothing and reading materials on her shelves) but the other two appear to be masters-level students or graduates with professional careers in finance or banking.
All three, obviously, speak English and have fairly well traveled, “international” attitudes about culture and values by looking at various objects and keep sakes in their apartments. They all have TVs with satellite type cable service. They all have very modern, Ikea-like living spaces (could be selection bias on our part though).
The last two hosts have had copies of novels from the “50 shades” series on their bookshelves, along with serious business and philosophical matter likely for school.
They’re all been young, likely early to mid 30s.
By way of comparison, in South America we stayed at a hostel run by a business, a hostel run by a middle-aged couple, a BNB run by a middle aged couple, an apartment run by a late middle aged man and an apartment owned by a young man whose family are the investors. I believe the last two in Argentina were AirBNB and we mightve made the rest of the arrangements directly via the enterprises’ websites.
And we are going to stay at a young man’s AirBNB here in Singapore but found out last minute that his building owner wouldn’t renew his permission letter letting him run the AirBNB legally.
