Guestimate: How would you estimate the number of commercial properties in a given city?

Someone asked on Mar 30, 2019 - 2 answers

Would you approach this question from the population or the land size point of view? Or is there a better angle to approach the question

I would use the population although it will be very sensitive to many assumptions.
It looks very difficult to make meaningful assumptions in terms of land size.

This is an uncommon question, to be honest.
There are a lot of assumptions involved with both the methods you suggest.

Two points from my side:

  1. Using population as sizing driver is extremely dangerous, not only in this case; if you had to choose one of the two, go for the second one (trying to extrapolate as a driver an area that you know well and that is COMPARABLE)
  2. Try to remember by heart some key numbers that could help you in situations like this one (e.g., # of commercial properties in your target Country, # companies in your target Country by size - small/medium/big): worst case scenario, you can use them to cross-check the values you come up with
