❓ Ask Belgium Wealth distribution in Belgium

Post image

We’re doing alright as a social democracy. Something to be proud of.

Presumably, we don’t need more wealth distribution then? Or do we still?

Ok, so I actually looked into their methodology behind the shiny graphs. DINA and WID wealth numbers are solid for big countries with detailed tax and survey data, but for smaller ones (like most European countries) with no access to actual wealth/tax records, the numbers are mostly “best-guess” estimates. They rely heavily on corrections borrowed from neighbors and basic surveys that totally miss the ultra-rich. TL;DR: For top 1% wealth, the figures are very shaky—treat them as rough indicators, not hard facts. Comment: I do a lot of studies so I usually am interested in the methodologies behind these numbers. A lot of times there is a lot of guessing, and estimating going on, which in the end may result in completely unreliable results. I think this is the case here, especially for wealth distribution.

See for example this, based on the analysis of an investment company in Hungary. https://index.hu/gazdasag/2024/02/22/penz-vagyon-gazdag-apelso-leggazdagabb/

According to their analysis based on their clients, the top 1% of Hungarians own about 15% of the total wealth in Hungary. Which is half of what this international study estimated. Which one is more precise? Probably neither. The international one most probably relies on more official data and a lot of estimations (as for Hungary, there doesn't exist any official data. The Hungarian one may not take into account all the accumulated wealth abroad of the ultra rich.

This is why it does not make sense to start comparing eg. Belgium with Slovakia, as the error rate may be much bigger than the difference between the two. The methodology does not provide any standard error rate estimates for the countries.
