Number of developed acres per capita

Why is it Important?

Land is a finite and valuable resource in every community. Both developed land and undeveloped land provide benefits to society. Developed land provides space for housing, offices, retail, and industry. In addition, developed land includes areas planted with lawn grasses, such as residential yards, parks, and golf courses.1 Undeveloped land, such as agricultural and natural resource land, benefits society by providing plant and wildlife habitat, air and water filtering, open space viewsheds, and recreational opportunities. The benefits of undeveloped land include positive externalities, which benefit the society at large but are not reflected in market valuation. This indicator measures the number of developed acres per capita.2 Decreases in this measure could be achieved by redevelopment of abandoned properties or by more compact new development. The benefits of reducing the number of developed acres per capita include decreasing the loss of agricultural and natural resource land, reducing the costs of providing infrastructure3, and meeting market demand for more compact development.4

How are we Doing?

In the baseline year 2006 there were 0.257 acres of developed land per capita in the St. Louis region. That number increased to 0.261 acres per capita in 2011. In 2001, developed land per capita was even lower, at 0.253 acres per person. Developed land per capita increased by 3.4 percent over the last decade, indicating that new developments are using more land per capita than older developments. The change in land use from 2006 to 2011 is due to the development of 20,779 acres of land and the net gain of 42,284 residents. The amount of newly developed land per new resident was 0.491 acres, almost twice as high as the region-wide land use per capita of 0.261 acres per person in 2011.

The map below shows where agricultural and natural resource land was converted to developed land over the last decade. Of the developments built between 2006 and 2011 on undeveloped land, the majority (83 percent) were built on cropland (6,900 acres), deciduous forest (6,600 acres), or hay/pastureland (3,600 acres). The conversion of these lands from undeveloped to developed resulted in a 0.7 to 1.0 percent loss of each type of undeveloped land. Other types of undeveloped land experienced larger percentage losses, including barren land (12.0 percent loss) and wetlands (2.0 percent loss); though the acres of land lost were lower for these categories (1,100 and 1,800 acres respectively).

In comparison with the peer metropolitan regions the St. Louis region has one of the highest levels of land use per capita, with 0.30 acres of developed acres per capita in 2011, compared to the peer metro average of 0.22 acres per capita in 2011. The St. Louis region also ranks near the top for change in land use, with a 0.9 percent increase in land use per capita in the 15-county metropolitan area from 2006 to 2011, compared to a peer metro average of -2.9 percent change in land use per capita. The change in land use per capita table reveals that most of the peer regions are developing more densely, whereas the St. Louis region is developing less densely.

1Land classifications for this indicator are based on the National Land Cover Database (NLCD) classification system, which is a modified version of the Anderson Land Cover Classification System.

2Developed land per capita is based on the HUD Flagship Sustainability Indicator Growth through Reinvestment. The Flagship Indicators were created for the Sustainable Community Initiative in an effort to develop a common national framework for measuring long-term progress toward sustainable communities. The Growth through Reinvestment indicator measures net acres of agricultural and natural resource land lost annually to development per new resident. In instances when the population increase is small or population declines the HUD Flagship indicator method appears to distort the scale of development that occurred in a region. Thus, the indicator was changed to a measure of developed land per total population, which more accurately accounts for the change in developed land. Both indicators measure the efficient use of land, and indicate the extent to which development consumes undeveloped land.
