holders into four groups ( couples where both have wealth, couples where 
one only has wealth, single men and single women ). T he reduction in 
sample size impairs the regularity of the data and I have therefore 
aggregated the four into two groups : married couples and single 
pwcsons. 
The calculated Pareto coefficients for income of wealth 
owners are much higher than the actual ones { able 1;. 
These calculated coefficients correspond more nearly to those of 
all income receivers including the wealthless ones -the great 
majority. They correspond also more nearly to these of the 
conditional income distributions in all wealth classes except the 
last three. In fact, if we exclude the open wealth class 
fro© the income distribution ( which might perhaps be motivated 
by the argument that it is not contained in the calculation of jC 
either ) then we get Pareto coefficients entirely in line with 
the calculated ones ( Table 1). The motivation is not entirely 
convincing and the results are inconclusive. 
Since the conditional income distributions in the 
wealth classes have been referred to several times, 4 give in the 
following data for couples where both husband and wife have wealth.
