Across Vanguard's plans, 79 percent of all workers eligible to save in a 401(k), 403(b) or similar account are doing so. Workers pulling down big paychecks have always been the most likely to save in a 401(k). The story hasn't been so good for lower-income workers, who likely feel less comfortable diverting some of their paycheck. But the participation rate for lower-income workers has been steadily climbing in recent years, and hit an estimated 65 percent last year. So while they still participate less often, the gap between how much lower-income workers participate and how much other groups do is narrowing.
