Only 10% of single women (with or without children) in Finland said they were finding it difficult to make ends meet in 2010, but this share goes up to 69% for single women in Greece. Total income is defined as the sum, at the household level, of the following components: 1) wage, salary and self-employment income of household members, 2) capital and property income, private pensions, private occupational pensions, and all kinds of private transfers, and 3) social security transfers from public sources. Total income is expressed in terms of “equivalent” household member, by dividing it by the square root of household size.
