Yeah, I think these brackets could use reworking for present-day interpretability. Working-age population traditionally starts at 16 in U.S. government statistics, since that's the traditional age where both mandatory schooling, and most child-labor-law restrictions ended. However the first part of that is becoming less true: currently only 30% of states still allow you to legally leave school at age 16. Another 20% have extended mandatory schooling to age 17, and 50% to age 18.
