Trend per Rooflines at @Shelterforce: "#HousingExtendedFamily": that is, household size increasing due to adult boomerang kids, hence a need for bigger apartments. With that, a need for better public spaces to accommodate household members escaping the said apartments.
Other trend noted, three years ago, per J.D. Power & Assocs.: Gen-Y teens feel less need to own cars. They're more concerned about their families' money worries, and "with
the advent of social media and other forms of electronic communities,
teens perceive less of a need to physically congregate, and less of a
need for a mode of transportation."
Conclusion: your basic American's kid's remaining means of autonomy, refuge and communication is a three-by-five square with earphones.
OK, we kinda knew that. But just saying.
