We walk about a lot and see a ton of people out of course. The majority are younger couples late 20s early 30s, usually with a dog, less often with a child, nearly always a baby/toddler in stroller. We rarely see a family with 2-3 kids in their teens, except over in the park. I think those families don't live around here, they just visit the park for a picnic etc.
I'd say 80% of the residences here are apartments, so many of these young couples live in apartments, most are new and quite luxurious apartments with amenities. It's a pretty good lifestyle for young couples making solid incomes, nothing to fix, no grass to mow. They can afford it, but they aren't building equity of course, and rents go up.
They could jump into a condo, but nearly all condos here are 1-2 bedroom, the newer ones are nice of course, but you have HOA fees and have to repair anything that breaks inside your condo. So, I think they get child 2 and look to jump to single family which means going further out, driving everywhere, mowing grass, etc.
