← Mortgage Rates Report The North Shore consists of many affluent suburbs north of Chicago, Illinois, bordering the shores of Lake Michigan. These communities fall within suburban Cook County and Lake County. The North Shore’s membership is often a topic of debate, and is sometimes expanded to include other affluent Chicago suburbs which do not border Lake Michigan. However, Evanston, Wilmette, Kenilworth, Winnetka, Glencoe, Highland Park, Lake Forest, and Lake Bluff are generally considered to be the core members of the North Shore, as all are affluent communities that border the lake just north of Chicago. Other suburbs such as Glenview, Northbrook, Deerfield, Highwood, Skokie, and Northfield are often considered to be a part of the North Shore, but do not border Lake Michigan.
