The median savings for American families whose wage earners are between 56 and 61, is $17,000. [1]

By “pensions” do you mean defined benefit plans only?
“In 1980, more than 148,000 DB plans covered 30 million active workers (38% of the workforce), but by 2008 just over 48,000 DB plans covered 18.9 million American active workers (13% of the workforce). Over the same period, the number of DC plans increased from 340,850 to 669,156 with an increase in active workers covered from 14 million (14% of the workforce) in 1980 to more than 67 million (46% of the workforce) in 2008.”
