Yes, because women generally approach the whole subject of money management in a different way to men. They're often less confident about planning their finances or have less time to deal with it as family and work tend to come first. Pension planning is the main area. Women invariably lose out because they often time out to look after a family.
Women tend to live longer than men, so they're likely to spend more years in retirement.
So, it's going to be more expensive to provide a pension for a woman, because it will have to pay out for longer. Working women should, therefore, start pension planning as soon as possible and aim to spend more on pensions when they return to work after a career break. Your husband may have the upper hand with his pension intact - although recent legislation is improving the position of women. First, make sure the short-term needs are covered. This means having enough money in a deposit account to cover emergencies and immediate spending such as holidays and birthdays etc.
