Agreed. It's not that millennials are different in any way (preferring high rises vs the McMansions of the Boomer generation), but instead the millennials are putting off children until much later and just don't have many school aged kids yet.

In 5-10 years, they'll be heading out of the cities just like their parents and grandparents did.

That's definitely one interpretation of at least some of the increasing millennial urbanization (such as it is) that I've read. That it's more about delaying moving to the suburbs/buying a house for a variety of reasons including marrying and having children later and the economy (especially of a few years back where of the currently available data is from).
