2.08. The coefficient for all incomes,including persons 
with no taxable wealth is not very different which is 
rather surprising. 
While the Dutch data are not worse than could be expected 
the Swedish data are not so good. The population of wealth 
holders is here (on account of the tax laws) split into 
four groups: Couples where both have wealth,couples where 
only one has wealth, single men and single women. The 
reduction of the sample impairs the regularity of the data 
and I have therefore aggregated the four into two 
groups,married couples and single persons. The calculated 
Pareto coefficients for income of wealth owners are much 
higher than the actual ones.These calculated coefficient 
correspond more nearly to those of all income receivers 
including the wealthless ones. We get,however, also a 
reasonably good correspondence with the actual income data 
for wealth owners if we exclude the open size class from 
the calculation. This might perhaps be motivated by the 
argument that the open size class does not enter the 
calculation of K either. The motivation is not entirely 
convincing and the results are somewhat inconclusive. 
Since the conditional income distributions in the various 
wealth classes have been referred to several times I give
