Density Is A Virtue
"We need to reclaim density as a solution to, not the cause of, problems facing our cities and suburbs... Density is essential to achieving the very qualities that make communities more livable - and cohesive. Neighborhoods in cities like Boston have lost as much as 50 percent of their pre-1950 population, which in turn supported the lively commercial districts with a sense of community that people seek to recapture. Worse, in an era of big-box retail and Internet shopping, it takes more people living within walking distance to support lively streets in 2003 than it did in 1950."
