The 2015 PLANSPONSOR Participant Survey was conducted in early March via a blind online questionnaire, using a broad sample of U.S. workers from ResearchNow, an online panel provider. A total of 1,077 full-time employed adults ages 23 and older responded to the 40-question survey, which covered a range of retirement savings habits and perceptions. Among respondents, 705 (65%) currently contribute to a 401(k), 403(b) or 457 defined contribution (DC) retirement plan, while 98 (11%) have access to a defined contribution plan but have elected not to join it; 217 respondents (20%) work at organizations with no defined contribution plan. The final data reflect a balance of demographic attributes, including gender, race/ethnicity, household income and formal education, similar to results from the 2014 survey. The sample was not weighted to reflect national averages. For more information, contact Brian O’Keefe at email@example.com.
