The outlying parts of the metropolitan area differ from the suburban areas of many other metropolitan areas.
Instead of a sprawling suburban skirt that encircles the urban area, the urban area abuts large swaths of farmland, with small to medium-sized villages that originated as farming communities.
But, as the willingness of professionals to commute longer distances has increased in recent decades, new residential developments have arisen on their edges, dotting the surrounding landscape.
Some of these villages are home to as many as 5,000 residents or more, but most are significantly smaller.

Most of these outlying communities, such as Savoy, Mahomet, St. Joseph, and arguably Rantoul and Monticello as well, are dependent on Champaign and Urbana for economic and infrastructure support.
Predominantly, these cities and villages lie in Champaign County.
These areas are populated to a substantial extent with commuters who work in Champaign or Urbana, but reside outside of the two cities.
Because higher paid professors, doctors and technology professionals who work for the University of Illinois at Urbana–Champaign, the many clinics and hospitals in town, or in the Research Park, are more likely to maintain cars for commuting longer distances and to afford owner-occupied single-family housing, these areas lacking in mass transit and high-density rental projects often have a higher median household income than Champaign or Urbana.

In addition to residential developments in the surrounding, formerly agricultural communities, residential neighborhoods are also growing up in unincorporated areas within a short radius of the city limits, while the cities themselves are also expanding to annex areas of new development.
While the annexed areas benefit from municipal services, developments that are willing to forego city sewer systems, libraries and police protection can enjoy the lower tax rates the surrounding townships levy, as fewer services are provided.
Areas currently under construction extend as far as around Rising Road west of I-57 and north and east of Willard Airport.
Some of this land is in Champaign Township, while some has been annexed to either Champaign or Savoy.
Additional land development is occurring north of I-74 in land annexed by both Champaign and Urbana.
On the eastern side of the city of Urbana, new business developments such as a Meijer, a planned Menards, and a commercial center with many restaurants and services have broken ground, as well as more suburban housing.

The issue of land development is often hotly contested by local governments.
In addition to arguments for and against development, the question of potential annexations, which remove property tax revenues from the surrounding townships while increasing the urban tax base (but also the demands on urban services) is a point of constant strife between the cities and the surrounding townships.
On the other hand, the availability of higher-valued housing in areas belonging to the townships or surrounding villages, which is paid for by workers earning their money within the urban infrastructure also represents a movement of potential tax dollars from Champaign and Urbana to their dependent areas.
