The Jewish population of West Rogers Park mushroomed to an estimated 48,000 in 1963, or about three-fourths of Chicago's Jewish population. Though it was still within city limits, the single-family homes and open sidewalks made the area highly attractive to upwardly mobile Jews. Today, the area's once-large population of Conservative, Reform, and secular Jews have mostly left for the suburbs. The neighborhood remains home to a largely Orthodox and ultra-Orthodox population. On Friday afternoons, Devon Avenue bustles with Jewish shoppers preparing for the Sabbath.
