Growing environmental awareness and a renewed interest in city living, combined with the negative connotations of sprawl, has generated more interest in New Urbanism and its philosophies regarding growth and development.

Transit-Oriented Development aims to create lasting communities of mixed income, race and lifestyle and return populations to the city but must overcome discrimination and prejudice and sustain a variety of housing opportunities to avoid neighborhoods from relapsing into isolated poor enclaves scourging current cities.

Today consumer housing demand is very different from post World War II America. Condo sales are booming, 37% of all households want dense "modest" homes and 71% of older households want to live within walking distance of transit.
