Generally expected outcome of economic growth is raising standard of living of the population. Its measurement is based on the basic macroeconomic aggregates such as GDP growth and GDP per capita. Such indicators, despite their clearly accepted significance, have a number of limitations that undermine their informational value. These indicators are the product of highly aggregated data. Therefore submitted paper focuses on the analysis of the income situation of the population. This approach allows to obtain objective indicators of the true state income differentiation, respectively income inequality in particular social groups. Society with substantial income differentiation is less resistant against various extreme impact of globalization. The analysis results show that in the years 2004-2011 the real income increased least in the group of self-employed persons by an average of 4.89% (k' = 1.0489), while in the group of pensioners, the real income increased by an average of 7.08 % (k' = 1.0708).
