GS are hugely popular at shows and always have been. Never mind all the working dogs there are (of course, most are not American types tho).
Add to this the non-registered dogs (yes, there are such things as purebred non-registered dogs!), and the totals are actually higher.
Also consider alot of German/Euro GS are here who are NEVER registered w/AKC - mostly undoubtedly the working dogs. Because that's abhorent to them. ;-)
GS are still very popular. I don't see them as much as Labs but I probably see them almost as much as Goldens overall (in real life, I mean). I see plenty ads in the classifieds when I bother to look. Besides mine, I've seen at least 2 different GS in my new neighborhood. Also, I've seen a real Collie (no, not a big Sheltie!)! Of course, we also have a big pot-bellied pig roaming around.....
It may depend on where you live.
I should also add, in my "old" neighborhood (my home all my life) just 5 min away and I only moved last year, there was also at least 1 other German Shepherd when I left.
