The traditional suburban low-density development is likely coming to an end due to changing demographics, higher energy prices, and a growing preference for non-motorized and public transportation. There is a big gap between the housing supply of the past and what will be needed in 20 years. If planning and zoning don't adapt to meet the needs of future generations, there could be another housing market collapse by the 2020s. Recommendations are given to reshape suburbs to match new market demands.
