"It’s a phenomenon showing up across the country, with clear implications for this election," states NewsHour anchor Judy Woodruff, who asks her guest to explain how the suburbs have changed in each of the three categories: age, diversity and political preference.

Most interesting was the first category, age, as it pertains to a debate seen here on Planetizen, namely, the supposed preference for millennials to live in cities.

"I was struck in doing some of this reporting by the amount of people I met who were millennials, people that are age 18 to 35 who live in suburbs not necessarily because it’s their first choice," answers Daniel Bush, PBS digital politics editor.

Sure, there are some people who move out there for all the traditional reasons, for a bigger home, for a better public school district, but a lot of younger people would prefer to live in cities, but they can no longer afford to, because major cities like D.C., like New York City, like Denver and other places, have become so expensive, that it’s hard to afford to live, to rent or even buy a home there.

In fact, a February Marketplace report indicated that November 26, 2014 "[h]alf of all millennial buyers are purchasing single-family homes in the suburbs." However, that report focused on how millennials were shaping suburbs to have urban amenities like public transit and walkable neighborhoods. Bush writes thats "they’re settling in suburbs and they’re bringing sort of a different culture and a different political attitude with them as well."
