2. Disability benefits

During your working years, you may suffer a serious illness or injury that prevents you from earning a living, potentially putting you and your family at financial risk. But if you qualify for Social Security on your earnings record, you may be able to get monthly disability benefits. You must have worked long enough in recent years, have a disability that is expected to last at least a year or result in death, and meet other requirements.

If you're receiving disability benefits, certain family members (such as your dependent children) may also be able to collect benefits based on your work record. Because eligibility requirements are strict, Social Security is not a substitute for other types of disability insurance, but it can provide basic income protection.

3. Retirement benefits

Retirement benefits are the cornerstone of the Social Security program. According to the Social Security Administration (SSA), because women are less often covered by retirement plans and live longer on average than men, they are typically more dependent on Social Security retirement benefits. Even if other sources of retirement income are exhausted, Social Security retirement benefits can't be outlived. Many women qualify for benefits based on their own work record, but if you're married, you may also qualify based on your husband's work record.
