Population Trends

With the post World War II suburban expansion of the Chicago metropolitan area, Lake County's population has increased steadily since 1950 when the county's population was just over 179,000. In 2000, the county's population was over 644,000. Most of Lake County's population lives in incorporated cities and villages as shown in the following table.

During the 1950s and 1960s, population growth occurred mostly in lake front communities such as Waukegan, North Chicago, Highland Park and Deerfield. During the 1980s and 1990s, population growth moved north and west to communities such as Vernon Hills, Gurnee, Grayslake, Mundelein, Round Lake Beach and Buffalo Grove.

Almost all the municipalities (47 out of 52) in Lake County gained population in the 1990s. Only 4 lost population and 1 remained zero (Lake County part of Wheeling). Waukegan represented the largest population increase with a net gain of over 18,500, followed by Gurnee and Grayslake with population increases of 15,133 and 11,118 respectively.

Also shown in the table are the population changes in the unincorporated townships. From 1950 to 2000, the total population of unincorporated areas of Lake County grew from 62,712 to 83,916, a net gain of 21,205 or 33.8%. 11 of the 18 townships increased their population in the unincorporated areas, while six lost population. Zion Township covers the same area as the City of Zion and has no unincorporated area or population.
