Illinois Population Growth
In Illinois' cities, population growth has stalled. Chicago was, for much of its early history, one of America's fastest growing cities. Between 1850 and 1930, the city grew by at least 25% each decade, and in some decades it doubled or even tripled in size. However, from the 1960s onwards, Chicago has been steadily shrinking and a city which was home to 3.5 million people in 1960 is home to just 2.7 million today.
The problem is widespread throughout Illinois, and if you look at the interactive map at the top of this article, you'll see that the number of people living in in most of the State's counties fell between 2000 and 2010 (the slightly peachy colour). Despite this, some counties (marked in dark blue) have seen rapid growth, sometimes upwards of 25% in the past decade, and it's this that has resulted in the state's overall growth figures.
Chicago, Largest City in Illinois
As you can see from the map above, most of the Illinois population is based in the North East of the state. Chicago, home to 2,695,598 people, remains the largest city in Illinois. It dwarfs the state's other cities – the next largest is Aurora, with 197,899 people.
This marks one of Illinois’ defining features – although it has a large urban population, it is spread through a number of smaller cities. Including Chicago, there are twelve cities with more than 75,000 people.
Many of these smaller cities make up a part of the Chicago Metropolitan Area (prosaically also known as Chicagoland), which holds between 8.3 and 9.8 million people, depending on how you classify its boundaries.
Cook County is the largest county in Illinois. It holds 5,194,675 people. The next largest county is neighboring Dupage, with 916,924 people. Almost half of the Illinois Population 2012 can be found in just those two counties.
