Data analysis
The average is one of the most familiar numbers in data analysis, and one of the easiest to misread. When a tiny fraction of cases carries most of the toll, the mean has to be read alongside the whole distribution."
Within-year concentration
A big year is usually a concentrated year. But the size of a total does not fix how the deaths beneath it are distributed.

Conflict data
Seven years account for half of UCDP's best-estimate organized-violence deaths since 1989. But the exact cutoff depends on fatality uncertainty, and five of those years form a recent consecutive cluster.
