Looking into this number was triggered by double checking the taxability of Social Security. What these numbers show is that looking at either mean (average) or median (mid point of all incomes), most households will have some of their Social Security benefit subject to income tax.
Keep in mind the MAGI (1/2 Social Security benefit + other taxable income + tax-free interest income) only has to be $44,000 a year for a couple for 85% of the Social Security benefit to be taxable. An interesting amount given that in theory beneficiaries paid for half of their benefit with after-tax income.

What is the Average Retirement Income and Median Retirement Income?
The best data about average retirement income comes from the US Census Bureau. The most recent data available is from 2016.
So the small gains suggested by recent research are not necessarily represented in the data below, but these numbers should be very close to reality for the average household:
Households Aged 55-64
Median Income $ 62,802
Mean Income $89,986
Households Aged 65-74:
Median Income $47,432
Mean Income $68,905
Households Aged 75 and Older:
Median Income. $30,635
Mean Income $45,989
