Per my usual practice, I downloaded the FAA Aircraft Registration database on 31 December. Here are the sizes of the number of aircraft that are registered as Experimental Amateur-Built. Note this does not include examples that are registered as Light Sport, or have a blank in the column where the type of registration is normally listed.

For each year, the fleet size shown is on the last day OF that year. Final row is the total number of EAB aircraft in the registry for that year.
