The industry in the eurozone is recovering slightly. The purchasing managers' index rose in January to 46.1, up from 45.1. Market expectations were at 45.4, according to preliminary figures.
The purchasing managers' index for the eurozone's service sector, however, fell. The index dropped to 51.4, down from 51.6 in December.
An index value above 50 traditionally indicates growth.
In Germany, the purchasing managers' index for both the manufacturing industry and the service sector rose more than expected, while the index for industry in France fell slightly.
