A high proportion of women in most countries report bad or poor health. Differences become considerable when education and, particularly, incomes and age are factored in. The largest improvements in self-assessed health have been observed among women aged 26–40 years with the highest incomes. Gender inequalities at work (such as wage inequality), at home (unequal burden of housework and their role as informal carers) and the wider community (ongoing acceptance of higher levels of violence against women) are important contributing factors.
