I guess, but I'm just saying walking downtown you just don't see families, kids anywhere...whereas in most other cities you see kids, families, retirees, students, workers, etc in the "public centers" of a city.
My experience is only anecdotal, but I think most city centers I've spent much time in (Austin, Houston, Tokyo) haven't had many families around during the work week either. If you go to fisherman's wharf, you'll find it crawling with families (undeniably mostly tourists), and most weekends you'll find Union Square swarmed as well.
