Social inequalities are multidimensional and affect different sectors of society.
Earnings in private sector
The 1st, 2nd and 3rd quintiles show similar average earnings and, over the years, the distance between them remains almost unchanged. In that period, the gap between the 4th quintile average earnings and the bottom three quintiles widened. Nevertheless, it is very far from the 5th quintile.
This economic and social crisis and the respective policies of austerity may dramatically intensify the growing of inequalities. A recent study  simulated the effects of austerity measures in the income of households. This analysis made use of EUROMOD (and SWITCH, for Ireland) to simulate the effects of austerity measures on the households’ disposable income. The analysis was focused on three kinds of austerity policies that were carried in order to “cut the public deficit or stem its growth”: direct taxes, benefits and pensions, pay cuts on public service workers. According to this study, Portugal is one of the countries where cuts in benefits and pensions had a more negative impact on the income of the less well off.
