Unemployment rates remain stubbornly high in the world’s most advanced economies, causing more headaches for policymakers trying to avoid another global recession.

Data released Tuesday by the Organization for Economic Cooperation and Development shows unemployment across the group’s 34 countries rose slightly to 8.3 percent in October, from 8.2 percent the month before.

The OECD says, in total, 45.1 million people in member states were jobless in October, with some of the biggest increases in Europe.

The euro area as a whole saw its unemployment rate edge up to 10.3 percent, the highest it has been since the height of the global financial crisis.

Spain and the Netherlands saw especially big jumps in unemployment, with Spain’s jobless rate hitting 22.8 percent. Analysts fear the ongoing economic woes in Spain could soon force the eurozone’s fourth largest economy to join Greece and other countries needing international assistance.

Some OECD members did manage to lower their jobless rates. Germany’s unemployment rate fell slightly in October to 5.5 percent.

November data from the United States also showed the unemployment rate declining in the world’s largest economy, falling to 8.6 percent .
