I'm interested in a ballpark estimate of how many buildings there currently are in total in OpenStreetMap. I'd also like to know roughly how many buildings in total there are in the world, so I can calculate the coverage, but it's mostly the total count that I'm after.

I've attempted to download the Planet.osm data file but the uncompressed version is too large for my computer, so I haven't been able to spin it up and run the analysis myself.

I'm not using any GIS software, but could do so if there's a path to establishing the answer. I was anticipating that the answer could be found using Clojure, Python or by loading the data into a PostGIS instance.

    Hi, I'm not sure why this has been downvoted but I'd love to know so I can improve the question? It would be less vague if I asked for the precise number, would that be more suitable?

    You show no effort of your own and your question is unclear (what GIS software are you using)

    Or the number of OSM elements with a building key: taginfo.openstreetmap.org/keys/building
