Look at the graph again. The last half decade from 2015-16 there is a trend up...and you can be sure the 2019/20 take up was higher. I didn't mention anything about the half decade previous to that.You’ve just posted something which shows in the previous five years it declined for two years in a row before increasing. I’m not sure what your point is as you seem to be arguing against your own statement that it has been rising every year for half a decade. It has not, regardless of whether you extrapolate the data or not.
Extrapolated data from surveys is by nature more prone to inaccuracy, the factual observed data shows a decrease in 2018/19 versus the year before in over 65s.
You’re wrong, it’s no big deal.
On extrapolation of data: it's filling in the data that is likely there if all surveys were completed and collated for final results. There's nothing inaccurate about it. If you think there is, then you maybe should take that up with the statisticians of the Nuffield Trust, who I'm sure will be very interested in your correction of their work.
