This chart was built from data sourced from the city of Bloomington's B Clear Data website. As of Aug. 7, 2023 the data set includes numbers just back to 2014. Previously the sanitation department's annual statistics dataset included data starting in 2004.

Here's a .tsv (tab separated value) file that includes years from 2004 through 2022: Sanitation Dataset from B Clear - combined sanitation-data-set-through-2022.tsv
