2020 Statewide Frequency Reports
The 2020 IYS was impacted by COVID-19 and the school shutdown that began on March 17, 2020. There was lower participation statewide, with sufficient data collected from only three of the four community types. Because of this, a report for the city of Chicago and a statewide report will not be produced for 2020.
