Much of the growth and demographic shifts in the United States over the last five and a half decades have been echoed on a smaller scale in Illinois. But there is one important exception: Illinois' population is growing at a slower rate than the country as a whole.
During the 1960 Census, the U.S. population was counted at 179 million people, while 10 million, or nearly 6 percent, of those people called Illinois home. According to 2013 estimates, Illinois is home to 12.9 million people, or only about 4 percent of the total U.S. population of 315 million.
But Illinois is similar to the rest of the country in that it has seen a higher percentage of women than men living here since 1960, according to U.S. Census Bureau information. The state has also seen an uptick in the median age of its population as large generations such as the Baby Boomers age, similarly to the whole country, from about 30 years old in 1980 to almost 37 in 2010.
Illinois has also seen an increase in minority populations since 1970, when a huge majority of the state's residents called themselves white. The number of people who are black, Hispanic or Asian has increased to the point where nearly 35 percent of all Illinoisans call themselves by one of these three designations. Race information is not available before 1970 because the Census only kept track of "white" and "non-white" identities in questionnaires from 1960 and earlier.
