The Maricopa County Transportation Excise Tax, often referred to as the “1/2 cent sales tax” is levied upon business activities in Maricopa County, including retail sales, contracting, utilities, rental of real and personal property, restaurant and bar receipts, and other activities. Transportation excise tax revenues are deposited in the Maricopa County Regional Area Road Fund (RARF) which is administered by the Arizona Department of Transportation. These revenues were the principal source of funding for the Regional Freeway System in Maricopa County and were dedicated by statute to the purchase of right-of-way, design and construction of new freeways, widening of existing freeways and highways, improvements to the arterial street system, regional bus service and high capacity transit services such as light rail.

The Phoenix metropolitan area is new by national standards, having developed primarily since World War II and particularly since 1970. However, settlement patterns were established in the 1800s, in part due to topographic features such as water courses and mountains. The war effort during World War II stimulated the growth of the Valley. After the war, a combination of events led to much faster growth. These included the desire of ex-servicemen stationed in the area during the war to return; improvements in air conditioning; charter government in Phoenix, which allowed a small pro-growth business group to gain power; and
aerospace and electronics firms siting facilities, in part because of the federal government’s designation of Fort Huachuca as the principal proving ground for electronic defense equipment. The modern period began around 1970, when a maturing metro area coincided with the baby-boom generation reaching adulthood. The result was even more rapid growth that has continued to the current time. Rapid growth of the Phoenix metro area is expected to continue for at least the next 50 years. Land and water availability should not restrict growth until after the current population of nearly three million exceeds seven million in 2050.

Maricopa County has experienced remarkable population growth for decades, and will continue to do so. But while expanding metro areas tend to pay close attention to physical infrastructure—diligently budgeting for roads, sewers, schools and the like—there is often a relative lack of attention to meeting the future demands for human services. Relying on the expertise from throughout the College of Public Programs, this report analyzes 12 critically important topics, including children and families, poverty, substance abuse, and Latinos.

Fast Growth in Metropolitan Phoenix is the first product of a comprehensive effort to describe and analyze the region’s growth. The Brookings Institution Center on Urban and Metropolitan Policy in Washington, D.C. presented the opportunity for this project to Morrison Institute for Public Policy. The story of growth in metropolitan Phoenix is a complicated, often surprising, tale. There is much to be proud of in the region. Yet there is also much to worry about, and much that needs to be done. Hits and Misses will have been successful if it becomes a catalyst for getting started.
