PARIS (AP) — Unemployment levels in the world's advanced economies could improve next year, even though the number of people without work will likely continue to rise in several European countries, a leading international economic body said Tuesday.

In a report published Tuesday, the Organization for Economic Cooperation and Development predicted that the jobless rate for the countries that use the euro would rise from 12.2 percent to 12.3 percent by the end of next year. Many countries, like Greece, Spain and Portugal will see a much sharper increase as their economies struggle to recover.

But good news is on the way for some countries. For the 34-country OECD, unemployment is projected to fall slightly next year from 8 percent to 7.8 percent. The United States could see its unemployment rate fall from 7.6 percent to 6.7 percent, while Germany's could drop from 5.3 to 4.7 percent.
