Although 2.2 million people in Germany are officially classed as underemployed, more than double that figure would like to have worked more in 2018 than they did.
New data released by the Federal Statistical Office (Destatis) revealed nearly 4.6 million residents met wider criteria for not having enough work.
The group was made up of 1.5 million unemployed people, 925,000 people among the so-called “hidden labor force,” and those officially classed as marginally employed.
Underemployed or marginally employed persons are those who are in work but who have the desire and are able to increase their hours. In 2018, they made up 5.3% of the workforce aged 15-74.
The Federal Statistical Office said those surveyed only wanted to increase their work time by a few hours a week and pointed to a strong economic performance that left 153,000 fewer jobless people last year.
Germany has seen a rise in those classed as marginally employed since a major reform of the welfare system in 2002. The government allowed the creation of Mini-Jobs, which pay €450 ($512) or less per month.
Separate figures released last November by the Federal Employment Agency revealed that one in five Germans is now marginally employed.
