What data are you referring to, specifically? I think the point that's being made by others is that if there's very little to no testing, and very little data sharing how can you know? Further, if the data collection and sharing isn't consistent across time, how can you compare the last few years to now?
I know I, personally, don't share any COVID data across the time span you're speaking of because it's apples to oranges in all data sets that I know of.
