I agree there's a growing divide there, and even a decent middle ground there of people who value maybe having a yard but want a park and shops and what not within bicycle distance and not be entirely car dependent.

I'm not entirely sure it's fully an age divide. Definitely age-weighted, I can agree. Other than family that grew up in NYC, most of my family >50 thinks I'm crazy for taking my kids on public transit and can't understand why I'd like to live closer in the city with kids compared to living in the sticks on a large property and a 15 minute drive to the grocery store. But there's also a lot of conservative younger-ish (millennial and younger) people who also seem to have that same mindset of wanting to live further out of the city and don't care or are against things like transit and tax dollars spent on city parks and bike lanes.

That example of the family of four where a four bedroom house is just too cramped for their needs I gave elsewhere? They're barely 30. They're absolutely not alone in what they're looking for.
