Complete Description:This study conducted by the U.S. Office of Personnel Management (OPM) examines rates of participation in the Federal Thrift Savings Plan (TSP) in calendar year 2007 by ethnicity and gender. OPM found that minorities are less likely to participate in TSP (82.5 percent of minorities versus 87.8 percent of non-minorities). When minorities do participate, they contribute roughly 25 percent less than their non-minority counterparts. Women are slightly more likely to participate in TSP (86.4 percent versus 85.8 percent of men), but contribute less money and tend to invest more conservatively. The mean balance of a female’s account is 22 percent lower than the mean male balance ($62,527 versus $79,819).
