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.
