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 62 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.
