Annexation and the Fiscal Fate of Cities

Annexing land appears to be an important route to economic health and development for the nation's urban areas.

An analysis of the relationship between the annexation patterns and fiscal health of the nation's largest cities shows that:

* A city's ability to annex land from its surrounding county is a primary determinant of its fiscal health. Cities with greater abilities to annex have much higher bond rating scores. Of cities in large metropolitan areas, every city that expanded its boundaries by as little as 15 percent between 1950 and 2000 had a high bond rating in 2002. Conversely, all cities with low bond ratings are those that had been unable to expand their boundaries.

* The ability to annex land varies widely by region and state. Most high-bond-rated cities are located in "big box" states (primarily in the South and West) where land is more easily annexed. Most low-bond-rated cities are in "little box" states (primarily in the Northeast and Midwest) where land is more difficult, or impossible, to annex.

* Annexation is far from an outmoded, dying practice. During the 1990s, about 90 percent of the central cities that could annex additional land did so. Collectively, in just one decade they expanded their municipal territory by more than 3,000 square miles.
