What goes into the Statistical Suppression Index
SSI is a weighted sum of six documented streams on a 0-10 scale: the census (weight 2.5), COVID mortality (2.0), the consumption survey (1.5), GDP methodology (1.5), statistical institutions (1.5) and the employment survey (1.0). Each stream carries a graded severity for each year: about 1.0 for a withheld or postponed release, 0.7 for a live methodology dispute and 0.3 for a release on a published schedule that is late. A resolved event keeps a smaller severity for a few years afterwards.
What follows. The index is transparent enough that anyone can replicate it from the public record of statistical events.
