(Bloomberg) -- Portugal’s unemployment rate rose in the three months through March, the first increase since 2016.

The unemployment rate climbed to 6.8 percent in the first quarter from 6.7 percent in the fourth quarter. It fell from 7.9 percent in the first quarter of 2018, the Lisbon-based National Statistics Institute said on its website.

Tourism has boosted the Portuguese economy, which in 2017 posted its strongest growth since 2000. That’s helped the country’s minority Socialist administration, which faces a general election in October, to lower the jobless rate and manage the budget deficit. The Bank of Portugal forecasts growth will slow to 1.7 percent this year.

Portugal’s output growth has been chiefly due to employment growth rather than increased productivity, the country’s central bank said in a statement on Wednesday. The economy expanded for a fifth consecutive year in 2018.
