Perhaps related is that the voting age population (vap) only increased ~30% of what would be predicted by the curve fit up to that point. Could be that some people died out of the vap early. Compounded with that, the voting eligible population (vep) increased exactly as predicted. Which means for each early demose of someone in the vap, someone else already in the vap became eligible when they hadn't been previously. Perhaps some states changed their laws about who was eligible?
