Thx for the info. It would be interesting to see similar stats from other countries that in the past were "success stories" but have had similar downturns like Mexico and Japan.
But Corney, what was the status of those newly created congs? Were they examples of a "new" cong C formed from the now defunct congs A and B? Or maybe a cong D formed from old congs A, B, and C? Could they be at least partly because of immigration, a huge issue in Germany? How can one know such details? New names could reflect the changing realities of territorial adjustments or just a broader geographical name that encompasses more area. Who knows?
