Nearly half of all women don't have a retirement strategy, despite the fact that 56 percent of women expect to self-fund their retirement through 401(k) plans, retirement accounts or other savings and investments.

According to Transamerica Center for Retirement Studies' latest research, "Juggling Current Priorities and Long-Term Security: Every Woman Needs Her Own Retirement Strategy," there's a "striking disconnect among women between how they envision their retirement and how they are preparing to realize that vision."

"Women face a number of unique circumstances, such as typically lower wages than men, time out of the workforce to be a parent or caregiver and a longer life expectancy, which present challenges for saving," says Catherine Collinson, president of the Transamerica Center for Retirement Studies. "As a society, we must do more to empower and equip women with the know-how to plan, save, and ultimately achieve a secure retirement."
