Populations, from the archive

Cohorts

204 populations published · 534 held back because one company would be too large a share of them

Measured on barges and towing vessels — the classes for which casualty records were retrieved when this finding was computed. Every other class Maury now holds is outside it, and no figure on this page includes one.

Why some populations are not published

534 cohorts exist in the archive but are not published, because a single operator holds more than a quarter of the hulls or fewer than ten operators are present. A statistic from such a cohort could be a statement about one company wearing the shape of a population. Those cohorts are listed as absent rather than widened until they pass.
