About this dataset

Context

The dataset tabulates the Cook County 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 Cook County 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 2023, the population of Cook County was 17,714, a 1.75% increase year-by-year from 2022. Previously, in 2022, Cook County population was 17,409, an increase of 0.85% compared to a population of 17,262 in 2021. Over the last 20 plus years, between 2000 and 2023, population of Cook County increased by 1,854. In this period, the peak population was 17,714 in the year 2023. The numbers suggest that the population has not reached its peak yet and is showing a trend of further growth. Source: U.S. Census Bureau Population Estimates Program (PEP).

Unincorporated Cook County population by political township based on the 2020 United States Census Block population data. The unincorporated area boundaries are based on data from 6/10/2022. How we aggregated the data:We identified Cook County unincorporated areas by filtering our Municipality feature class. Cook County Forest Preserves holdings were removed from the unincorporated areas before aggregating data. The ESRI ArcGIS Pro Apportion Polygon tool was used to aggregate and apportion the Census Block population by township area. Unincorporated political townships with a population of zero were removed. Data Sources:

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Face refers to the areal (polygon) topological primitives that make up MTDB. A face is bounded by one or more edges; its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face. The Topological Faces Shapefile contains the attributes of each topological primitive face. Each face has a unique topological face identifier (TFID) value. Each face in the shapefile includes the key geographic area codes for all geographic areas for which the Census Bureau tabulates data for both the 2020 Census and the annual estimates and surveys. The geometries of each of these geographic areas can then be built by dissolving the face geometries on the appropriate key geographic area codes in the Topological Faces Shapefile.
