The county is divided into nine different townships: Downers Grove, Lisle, Naperville, York, Milton, Winfield, Addison, Bloomingdale and Wayne.

Notable features
Long known as one of the nation's wealthiest counties, DuPage County has transformed itself from a primarily agricultural economy to one rich in many different types of commerce. Today, DuPage County boasts a personal per capita income which is highest in the state, with Lake County a close second. The county's personal per capita income is the highest in the midwest (of counties with population under 1 million) and 24th highest in the nation. Over twenty of the county's towns have median (single family) house values of over $400,000. However, with the recent housing bubble and the exaggerated incomes associated with alt-a "liar-loans," these statistics do not reflect real wealth, as the wave of foreclosures starting in 2007 indicate. The median household income for Dupage county is only $66,000 (http://quickfacts.census.gov/qfd/states/17/17043.html), approximately 50% higher than the US median household income. The bursting of the debt-fueled speculative housing bubble is already having a profound effect on the property values in Dupage county, where sellers in recent years were asking as much as $350,000 for a 1,000 square foot shack. Housing prices are expected to continue a downward plunge throughout 2008 and 2009.
Much of the county has been incorporated into municipalities.[1]

Fiscal year 2007 will be the last year of the DuPage Water Commission intergovernmental transfer, meaning that the County budget will lose approximately $15 million in revenue.
