In addition, we are also becoming older. And a new analysis by the Center says these trends are playing out differently across community types … urban, suburban, and rural. On this week's Perspective program a look at not only the trends, but also what they may portend for our country.     Guests: Kim Parker, the director of social trends research at the Pew Research Center, and Juliana Horowitz, the associate director of social trends research at the Pew Research Center.   Perspective is a weekly public affairs program hosted by Richard Baker, communications professor at Kansas State University.
