One in four people who completed a debt assessment with Citizens Advice in 2021 was in a single-parent family.
In total, around 280,000 people in England and Wales sought one-to-one help with debt in 2021, the charity said, with many more using its website.
Within this group, nearly 70,000 went on to complete a full debt assessment, which examines their income and spending, as well as their debts.
