Physical Infrastructure: Crosscutting Issues Planning Conference Report

The nation's physical infrastructure consists of a broad array of systems and facilities, including transportation networks, such as roads, airports, rail, and mass transit; housing; federal buildings including postal facilities; and telecommunications services. In the 21st century, the following trends are likely to influence the nation's need for interconnected infrastructure systems and services: (1) the total population of the United States is expected to increase by nearly 50 million people, or about 17 percent; (2) the number of Americans aged 55 and over is expected to increase by about 60 percent; and (3) the suburbanization of population and employment will continue. The steps that the nation takes to anticipate these trends in infrastructure policy and investments will have a direct effect on America's economy and quality of life. To better understand these connections, GAO sponsored a conference in June 2001 to consider infrastructure issues from a crosscutting perspective. This report discusses the findings and conclusions of that conference.
