Distribution and Participation

Figures from the World Inequality Database show that the top one percent share of pre-tax fiscal income rose from around six per cent the mid-1980s to around 12 per cent in the mid-2010s.

Figures from Eurostat show that the share of the population in non-agricultural employment rose from around 25 per cent in the mid-1980s to 45 per cent in 2019.

The distribution of fiscal income is a useful indicator but it is measured using a changing sub-sample of the population: only those who have fiscal income, i.e. those with tax returns filed either by themselves or there employer. 

Changes in participation could have an effect on how changes in the distribution of pre-tax fiscal income should be interpreted as changes in the shares of pre-tax fiscal income among recipients may not necessarily reflect changes in the distribution of that income across the full population.

From the EU-SILC we do have a top one per cent share for disposable income, albeit for a shorter time period.  Of course, there may be issues with the use of a survey to measure incomes at the extreme of the distribution (super-high incomes may be under-represented in the sample) but to the extent that this is a consistent problem with income surveys the trends in incomes shares towards the top of the distribution may be relatively unaffected.

For what it’s worth, the bottom cut-off for the top one per cent in 2019 was an equivalised disposable income of just over €100,000 or €210,000 for a household of 2 adults and 2 children.  The SILC suggests there are close to 50,000 people living in such households.
