Pensions might seem like a distant reality to young Europeans, but many are worried about whether they will actually get one.

Despite 22% naming pensions as a primary concern, 30% of those surveyed say they only have a limited knowledge of how the system works, according to new research by independent think tank Friends of Europe.

Young Danish and French respondents have the least knowledge of how the pension system functions, at 34% and 33%, respectively, the study shows.

In contrast, Italians and Spaniards claim to have the strongest knowledge.

"My biggest concern about pensions is that the pension system no longer works for my generation and those after us," said one French respondent in the survey. "That we have to pay the price for poor political and economic choices."
