Norway topped the table with an average wage of €3,644, some 34% more than in Spain.
The study, known as the Adecco Monitor of Employment Opportunity and Satisfaction, is based on figures from the last five years, according to the Europa Press agency.

Italy is below the European average but still above Spain with €1,898.
Average wages in Ireland (€2,866) and Cyprus (€1,657) are still higher than in Spain despite both countries having their economies bailed out, although the report states that the situation in Cyprus is likely to change.
There are twelve European countries with lower average wages than Spain, including Portugal (€1,078) and Greece, for which no reliable data exists.
