Seven more incorporated villages sit fully inside the county but outside the top 25: Winfield (9,835), Itasca (9,543), Clarendon Hills (8,702), Oak Brook (8,163), Oakbrook Terrace (2,751) and Wayne (2,286), plus the unincorporated Willowbrook (9,236). Several of the county’s largest names straddle a county line, which is why their populations above count residents outside DuPage too: Naperville and Bolingbrook both extend into Will County, and Bartlett, Hanover Park, Bensenville and Burr Ridge each reach into Cook County. Aurora, Schaumburg, Elk Grove Village, Lemont, Willow Springs, St. Charles, Batavia and even a corner of the city of Chicago all touch DuPage, but each has only a small sliver here and its population is centered in a neighboring county, so none of the eight is listed above.<\/p>\n
