The instruments behind the rates we report.

Every rate we report comes out of a defined statistical instrument. We write each one down in full — what it measures, how it aggregates, what it deliberately leaves out — and publish it here, so you can follow a figure back to the counts it came from, and so can whoever audits it later.

The papers below are definitional work in a running series, published in full and open to argument.

The Wilson interval carries the uncertainty of every rate in the series. It keeps its behavior at the low rates a violation rate lives in.
