United States Census data for the city of Chicago

The United States Census website is a powerful tool that allows users to access, filter, and download thousands of data tables; maps; city, county, and state profiles; and reports. These resources include a variety of data that come from the decennial census as well as the annual American Community Survey. By manipulating the filters applied to various data tables, you can access detailed information about the population of very young children in Chicago. For example, Table B09001 can be filtered to display the number of children under age 18 by age group, including counts of children under 3, 3 and 4 and 5 year olds in the city of Chicago. These same filters can be applied to many other data tables that include, for example, information about family type, poverty status, and nativity for children broken down by age group.
