Poland's economy and Gross Domestic Product (GDP) is currently the sixth largest in the European Union by nominal standards, and the fifth largest by purchasing power parity. It is also one of the fastest growing within the Union. Around 60% of the employed population belongs to the tertiary service sector, 30% to industry and manufacturing, and the remaining 10% to the agricultural sector. Although Poland is a member of EU's single market, the country has not adopted the Euro as legal tender and maintains its own currency – the Polish złoty (zł, PLN).
