In this article, we break down the Facebook and Instagram audience in Illinois across four practical layers: Total Audience, Engaged Shoppers, Frequent International Travelers, and Technology Early Adopters.
We collected the numbers via the Meta Marketing API. All estimates in this article are based on the minimum reach value from Meta’s audience forecasting and are calculated only for Facebook and Instagram placements in In Feed and In Stories. If you include Audience Network or other placements, or if you use the maximum reach estimate, the reported audience sizes can be materially higher.
