According to the information collected by the website run by the Francisco Manuel dos Santos Foundation, the purchasing power standard (PPS) in Portugal in 2016 was 25,881 PPS, with the country in 18th in a ranking led by Luxembourg (with 54,547 PPS).
In its Portrait of Portugal in Europe, published as part of European Statistics Day, Pordata said the EU average last year was 35,754 PPS.
In the last places on the list are Hungary, Romania and Bulgaria, the latter with 16,044 PPS.
PPS, the Purchasing Power Standard, is a fictional currency used to compare levels of welfare and spending across countries, nullifying differences in price levels.
In terms of the national minimum wage, in 2016 Portugal was ranked 11th on the list of EU countries, with 711 PPS, Luxembourg (with 1,615 PPS) in first place and Bulgaria (491 PPS) in last place.
In a separate study, Pordata also found Portugal has the third highest rate in the European Union (EU) of population employed with a temporary contract.
The number of employed people with temporary contracts increased between 2000 and 2016 and currently 22.3 percent of the population is hired on temporary contracts, compared to the EU average of 14.2 percent, according to Pordata.
Portugal is in third place, after Poland (27.5 percent) and Spain which has decreased its percentage of temporary workers in the last decade, researchers said.
Portugal is ranked in 16th place among EU countries with the most part- time contracts with 11.9 percent of the total population employed on a part- time basis.
