True, but all these numbers from other countries are also fudged, so you can compare them
Just to add for others that might not know why you're mentioning this. The thing that they don't tell you about inflation is that there's a basket, yes, but if the item gets too expensive then they simply switch to a cheaper alternative. So, if beef gets too expensive, they track chicken, and so on. It's clearly not an indication of "real world" inflation.
