I’m not sure how the politics play out but a stat that is always off in the same direction, always over and never under, is what some statisticians call “biased.”
You can have non-biased indicators that have error with mean 0.
Maybe a better question, when judging current operations, is how precise the biased estimates are becoming overtime. Is the size of the error increasing or decreasing.
