With the 2012 elections not that far off, Republicans are taking on President Obama’s high-speed rail plan.

The President's high-speed rail plan is more 'I think I can' than 'Yes, we can.'

American infrastructure, one of the central themes of President Obama's State of the Union address this week, isn’t the only thing that’s aging. Baby boomers are too. This year, the first baby boomers turn 65 -- and many will celebrate their birthdays in neighborhoods that were not designed for senior citizens. We’re talking about America’s suburbs. They were ridiculed as a bastion of conformity in the song “Little Boxes.” But in fact, some communities are breaking away from suburban sameness in order to make the infrastructure changes that baby boomers are about to require. Correspondent Maria Hinojosa has this Blueprint America report.

In the shadow of the recession, a great migration of sorts has occurred in the suburbs. Though, since the rows of houses were first built outside America's city limits, this population turnover has been a long time coming. A Brookings Institution preview of the 2010 Census released last year shows that the nuclear family out in suburbia with its kids and white-picket fences and two-car garages has been a misscharacterization for at least the last decade, if not longer. Racial and ethnic minorities now account for a majority of the population in 17 metropolitan areas, most in the South and Southwest, but regions like New York in the Northeast will soon follow. Also, since 2000, the number of 55to 64 year olds nationwide grew by nearly 50 percent. This past January, the first baby boomers turned 65. Brookings demographer William H. Frey talks to Blueprint America about his findings, and what all of it means to a new kind of suburbia.

America is on the brink of a massive demographic shift as the first of the baby boom turned 65 this New Year. Already, an estimated 39 million people across the country are 65 or older -- just over 13 percent of the population. By 2030, when all baby boomers will be over 65, there will be 72 million seniors -- about 20 percent of the population. And our suburbs -- where half of all Americans live today -- will be hardest hit. Elinor Ginzler, AARP's Director of Livable Communities, talks to Blueprint America about how Americans can live in suburbia as they age. Already, the suburbs are a tough place to get around. Getting older won’t make it any easier.

Podcast: Can better urban infrastructure make Americans healthier?

President Eisenhower's dream of an Interstate Highway system was bold and shaped America's future in the second half of the 20th century. These days the magnitude of his project is largely forgotten, and the vast system of roads is taken for granted as part of American life. But was it always so easy to see Ike's vision for the country?

A new and improved public transit system --funded with stimulus dollars -- helps the poor get to work in rural Mississippi.
