Generation Size Chart
Every living generation ranked by how many people are in it, with the honest caveat that the top three sit inside each other's margin of error.
The three largest living generations sit within a few percent of one another, which is well inside the uncertainty of all three estimates — "largest generation ever" is a headline rather than a finding.
