Indicator Definition:
Atkinson (1970) proposed this class of inequality measures with a weighting parameter ε which measures aversion to inequality. As ε rises, the index becomes more sensitive to transfers at the lower end of the distribution and less sensitive to transfers at the top. The limit case, ε→0, the index reflects the Function of Rawls which only takes account of transfers to the very lowest income group; at the other extreme, when ε=0, we obtain the linear utility function. This ranks distributions solely according to total income.
The indicator "Atkinson, A(.5)" stands at 0.2137 as of 12/31/2014, the lowest value at least since 12/31/2009, the period currently displayed.
Regarding the One-Year-Change of the series, the current value constitutes a decrease of -2.73 percent compared to the value the year prior.
The 1 year change in percent is -2.73.
The 3 year change in percent is -4.14.
The 5 year change in percent is -4.00.
