As a result, too many Americans are unable to participate fully in the economy and in civil society.

The New Urban Crisis

Richard Florida

Richard Florida writes that Donald Trump’s thinking about cities is a product of the old urban crisis of the 1960s and ‘70s - the staggeringly high rates of crime and poverty, economic and social dysfunction, and fiscal collapse that he witnessed in his native New York in the early years of his career. But, his stunning victory over Hillary Clinton is a product of the backlash against what I have come to call the New Urban Crisis of burgeoning economic inequality--the widening divides between rich and poor; the staggering unaffordability of housing in our leading cities, tech hubs, and knowledge-centers like New York, LA, San Francisco, Boston, Seattle, and Washington DC.

Improving the Evidence Base for Access to Quality Pre-K

John Fantuzzo, Katie Barghaus, & Whitney LeBoeuf

Early childhood education has captured the nation’s attention and holds a rare spot in the center of the political aisle. This is not surprising given that a quality Pre-K experience can save the public at least three dollars for every dollar spent, particularly for children who live in poverty and experience numerous risks to their educational success. In Philadelphia, the poorest of the ten largest cities in America, Mayor Kenney established the Commission on Universal Pre-K to expand access to quality Pre-K in the city, with the ultimate goal of universal access for all three- and four-year-old children. This introduced one of the most important decisions in Kenney’s early term as Mayor—how to expand quality Pre-K given limited funds and thousands of children in need. As researchers, the critical question for us became how to provide useful information to Kenney’s Commission in a timely manner so they can allocate funds to serve the most vulnerable children first.

Housing and Opportunity

Arthur Acolin and Susan Wachter

For much of U.S. history, moving to markets with better jobs has been a primary means for low-income workers to rise out of poverty and access opportunity. Recently, however, there has been a decrease in the rate with which workers have relocated to markets with better work opportunities. Average annual mobility has declined from nearly 20 between 1948 and 1980 to only about 10 percent in 2015 (U.S. Census 2016), which may be signaling a fundamental shift in the ability for workers to relocate to regions with greater job opportunities.

Expert Voices 2017: America’s Urban Infrastructure

Penn IUR

In his inauguration speech, President Trump characterized America's infrastructure as having “fallen into disrepair and decay” and promised to “build new roads, and highways, and bridges, and airports, and tunnels, and railways.” Similarly, over the course of the presidential campaign, Trump vowed to develop "the next generation" of American infrastructure and "send new skyscrapers soaring."
