What it means
Violation 1 appears on the Chicago Department of Public Health’s inspection checklist as “Person in Charge Present, Demonstrates Knowledge, and Performs Duties.” Its position on that form places it in the priority band — the city does not publish a severity field, so this is inferred from the code number, which is how the form itself is ordered.

How these figures were calculated
The city publishes the records but not these rates. They were derived from 56,625 inspections since 2022 with a graded result of Pass, Pass w/ Conditions or Fail, with each violation string parsed for its leading code number. The rate above is the share of inspections citing violation 1 that ended in a failure. A single inspection commonly cites several violations, so codes are not mutually exclusive. Anyone can reproduce this from the dataset linked above.
