In reply to the discussion: Average monthly benefit for retirees on Social Security $1,230. [View all]PoliticAverse
(26,366 posts)It's apparent they are using the 'arithmetic mean' for the $1,230. figure, since that's what they are using in this table:
http://www.ssa.gov/policy/docs/quickfacts/stat_snapshot/
which lists the 'average' SS OASI benefit of $1,203.72 (46,630,000 recipients, $56,129,000,000 in payments,
arithmetic mean payment: $1,203.72) for August 2013. The number that half the recipients get more than, half
get less than, is the 'median' which isn't specified. We don't know how close the median would be to the arithmetic
mean without knowing the distribution of the payments (if the distribution were a bell shaped curve for example -it
isn't for SS payments- the median and the arithmetic mean would be the same).
