Green Bay Trail, a popular rails-to-trails bicycle path that begins in Wilmette and runs north all the way to the Illinois Beach State Park in Zion. Despite being very nearly an enclave within Highland Park, Highwood has very different demographic characteristics than its neighbors. While its median income is close to the average for the state of Illinois, it has a much lower median income than neighboring municipalities. It is more densely populated, and is the only community on the North Shore where non-Hispanic whites do not constitute a majority of the population. Expansion of the definition It is becoming common for businesses in numerous nearby inland Chicago suburbs to name themselves as part of the "North Shore". Real estate and other marketers notably use the term for Maine, New Trier, Niles, Northfield, and Norwood Townships, as well as those of southern Lake County and other nearby communities. The former North Shore magazine had special advertising editions not only for Evanston, Winnetka, Lake Forest, and Lake Bluff, but also for Skokie, Glenview, Northbrook, Barrington, Bannockburn, and Riverwoods. Chicago's North Shore Convention & Visitors Bureau's markets the City of Evanston and the Villages of Skokie, Glenview, Northbrook and Winnetka. More recently, a community newspaper known as "What's Happening" began mailing out its publication to what it characterizes as the "16 affluent North Shore suburbs": Bannockburn, Buffalo Grove, Deerfield, Fort Sheridan, Skokie, Glencoe, Glenview, Highland Park, Kenilworth, Libertyville, Lincolnshire, Northbrook, Northfield, Riverwoods, Vernon Hills, Wilmette, and Winnetka. Overall, the general usage of the term "North Shore" may at times be applied to the following suburbs:Bannockburn; Buffalo Grove; Deerfield; Des Plaines; Evanston; Glencoe; Glenview; Golf; Green Oaks; Harwood Heights; Highland Park; Highwood; Kenilworth; Lake Bluff; Lake Forest; Libertyville; Lincolnshire; Lincolnwood; Mettawa; Morton Grove; Mundelein; Niles; Norridge; Northbrook; Northfield; Park Ridge; Riverwoods; Rosemont; Skokie; Vernon Hills; Wheeling; Wilmette; and Winnetka. This geographic area favored by marketeers extends from Chicago’s northern boundary into southern Lake County and from Lake Michigan to O’Hare Airport.
