401(k) assets make up majority of DC assets

More than 70% of the roughly $11 trillion in defined contribution assets were in 401(k) plans at the end of 2021. Another 12% were held by 403(b) plans.

A combined 51% of DC plans come from households that earn at least $100,000 annually. For those at the other end of the spectrum, households with income below $50,000 account for 14% of plans.
