Population estimates by the U.S. Census Bureau by U.S. Census Block.

NOTE, 6/9/2021: An Age 12-17 column has been added to this dataset. See http://dev.cityofchicago.org/open%20data/data%20portal/2021/06/09/covid-vaccination-age-groups.html for details. -- Population totals for groupings commonly used in other datasets.

Not all values are available for all years.

Note that because the "Citywide" rows roll up the values from the individual ZIP Codes and the "Age 12-17," "Age 18+," and "Age 65+" columns overlap other age categories, as well as each other in some cases, care should be taken in summing values to avoid accidental double-counting. The "Age 12-17" column only includes children who live in households.
