Having a strong domestic market, low private debt, low unemployment rate, flexible currency, and not being dependent on a single export sector, Poland is the only European economy to have avoided the recession of 2008. The country is the 20th largest exporter of goods and services in the world and its most successful exports include machinery, furniture, food products, clothing, shoes, cosmetics and video games. Exports of goods and services are valued at approximately 56% of GDP, as of 2020. Poland's largest trading partners include Germany, Czech Republic, United Kingdom, France and Italy. In September 2018, the unemployment rate was estimated at 5.7%, one of the lowest in the European Union. In 2019, Poland passed a law that would exempt workers under the age of 26 from income tax.
