About this dataset

Context

The dataset tabulates the data for the Illinois population pyramid, which represents the Illinois population distribution across age and gender, using estimates from the U.S. Census Bureau American Community Survey (ACS) 2019-2023 5-Year Estimates. It lists the male and female population for each age group, along with the total population for those age groups. Higher numbers at the bottom of the table suggest population growth, whereas higher numbers at the top indicate declining birth rates. Furthermore, the dataset can be utilized to understand the youth dependency ratio, old-age dependency ratio, total dependency ratio, and potential support ratio.

Key observations

• Youth dependency ratio, which is the number of children aged 0-14 per 100 persons aged 15-64, for Illinois, is 27.7.
• Old-age dependency ratio, which is the number of persons aged 65 or over per 100 persons aged 15-64, for Illinois, is 25.3.
• Total dependency ratio for Illinois is 53.0.
• Potential support ratio, which is the number of youth (working age population) per elderly, for Illinois is 3.9.

About this dataset

Context

The dataset tabulates the Illinois population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of Illinois across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2024, the population of Illinois was 12.71 million, a 0.54% increase year-by-year from 2023. Previously, in 2023, Illinois population was 12.64 million, an increase of 0.16% compared to a population of 12.62 million in 2022. Over the last 20 plus years, between 2000 and 2024, population of Illinois increased by 272,590. In this period, the peak population was 12.9 million in the year 2009. The numbers suggest that the population has already reached its peak and is showing a trend of decline. Source: U.S. Census Bureau Population Estimates Program (PEP).
