So while I did not know this for a fact until today, I have recently talked about how I have not seen many kids around Belltown (this is of course not including the ones from New Horizons) when I am out and about doing various things. Of course we have the tourist families walking through from Downtown to Seattle Center, but I am talking kids living in Belltown. So yesterday I saw a post on Reddit* about neighborhoods in Seattle w/o kids, while I did not post my thoughts on it others did. Then today apparently the Seattle Times made a blog post about the Reddit story and had a nice post and breakdown of some surrounding neighborhoods without kids based off a 2013 Experian estimate. Below you will find links to the Reddit story and to the blog post on Seattle Times.
