Oh I just realised this from way back last Thursday. Oh well another interesting diary I missed.
Since the table also gives the ratio of those active in the workforce, I put the numbers of the table in a spreadsheet - out came:
Danemark 9.0 (map: 4.6) Roy.-Uni 13.7 (map: 9.3) Allemagne 13.1 Espagne 28.1 (map: 22.2) France 26.6 (map: 17.4) Italie 30.8 (map: 26.3) Pologne 65.4
The remaining difference is either due to data for differing years (no date given for the maps) - or (more likely given that the difference is strongest for high-childbearing-rate Denmark, then France) the inclusion of under-15 for the map. *Lunatic*, n. One whose delusions are out of fashion.
