This answer is for US only, since the question is tagged FAA
I don't know how the information is collected, but if you google "air operations xxx" where xxx is the FAA identifier for your airport, you'll find a bunch of sites that report this information.
For example, go to https://www.fltplan.com, select "Airport/FBO info", find your airport, scroll down to the tabbed section above the runway info and select 'aircraft data'.
AOPA has similar info: go to https://www.aopa.org/destinations/, find your airport, then look for the section "Aircraft & Activity".
https://skyvector.com also has this - click on the Airports button at the top left, find your airport, then look for "Operational Statistics".
