Around 7.5 percent of Germans over the age of 16 — roughly 5.14 million people —  said they didn't have enough money to regularly eat a proper meal in 2017.

In a response to a parliamentary inquiry from the Left party, the Federal Statistics Office also reported that almost a third of unemployed persons in Germany are unable to regularly eat a nutritious meal.

The data is based on respondents' self-assessments in a 2017 EU survey on income, social inclusion and living conditions.

The same survey found that around a third of Germans over the age of 16 — roughly 21 million, or 30.4 percent — are not in the position to afford an unexpected expense of €1,000 ($1,140), such as paying for car repairs or a new washing machine.

The percentage of unemployed Germans who couldn't pay an unexpected cost of that amount was 80 percent.

"Poverty is not a marginal phenomenon in Germany, but runs throughout the population," Left party social policy spokesperson Sabine Zimmermann told the Neue Osnabrücker Zeitung newspaper, which first reported the figures.

To solve the problem, the government needed to increase the minimum wage from €9.19 ($10.49) to €12 an hour, abolish "systematic" low-wage employment and end sanctions against people who claim unemployment benefit, she said.
