Out of interest i did a very rough calculation of what inflation-adjusted numbers might look like. I pulled 4% per year inflation out of my ear, and came up with:

    38.552 €bn * 1.04^(2016-2002)
    =>
    66.76 €bn

..which is uncannily close to your numbers. Inflation probably wasn't exactly 4% YoY, but if it is, then in real Euros, the expenditure per population has decreased.
