No. No kids, not having any. In our 30s and not big fans of 24/7 noise and busy-ness, or having no space or land, or the problems that come with living in city centres. Nice to be able to opt in and out as mentioned earlier, in our case via 20 minutes on a tram.
That was a bit reductionist, of course not everyone who lives in surburbia has kids, but having kids means you may live in a different kind of place to what you would choose if you didn't have kids. It doesn't necessarily tell you much about your preferences unconstrained by the needs of children or financial realities etc.
