For ages I’d been playing about with
various ways to try and show the effect of bracket creep in a chart. Over the
last year or so, I’ve settled on one that illustrates the combined effect of
creep and inflation, plus whatever measures have been put place in the
tax-transfer system that add to or subtract from them. I thought the format was
reasonably self-explanatory, but when I use it for charts on Twitter I get more
than the usual number of requests to explain just what I’m trying to show.
So here goes.
