The grade is the average of the six force scores, and can sit at most two bands above the city's third-weakest force. AAA and AA need all six forces scored.

How to read the table: every measure is scored from 0 to 100 against a fixed benchmark (the line under each measure), not against other cities. Adding cities never changes this score. Black bars = a score below 15.
