Personal income postion
Our Classification
The logarithm of the income of an individual relative to the mean income.
It is approximated using data on individual income quartiles and the standard deviation of income. The latter is calculated as ó=log(Y90/Y10)/3.28 assuming a lognormal distribution for income where Y90/Y10 is the 90/10 ratio from the Luxembourg Income Study. Using the midpoints of the four income quartiles, the log of average income for individuals in the first, second, third and fourth quartiles equals logY -1.15ó, logY -0.32ó, logY+0.32ó, logY+1.15ó, where Y is mean income per capita. Hence Personal Income Position equals -1.15ó, -0.32ó, 0.32ó and 1.15ó, respectively
