How has market income growth differed across household income groups?
Core argument: Market income for the top quintile of U.S. households grew 101% between 1979 and 2016, versus 32% for the bottom quintile and 32%–46% for the middle three quintiles.
Between 1979 and 2016, market income for the top quintile grew by 101%, while the bottom quintile saw a modest increase of 32%. The middle three quintiles experienced growth rates ranging from 32% to 46%. This disparity highlights the increasing concentration of income among higher earners. In 2016, the top quintile received 55% of total market income, up from 43% in 1979, while the bottom quintile's share decreased from 6% to 4%. These shifts underscore the widening income inequality over the decades. The data suggests that policy interventions may be necessary to address the growing economic divide and ensure more equitable income distribution across all quintiles.








Ed Comment:Lowest quintile: From (25,700 net taxes and transfers-17,200 market = 8,5000 gov handouts)/17200 market = 49% handouts as a share of market income to (48,900-25,300=23,600)/25,300 = 93%!!! WTF? The changes are too large to leave unexplained. Middle: from (55.7-67.6)/67.0=18% tax rate to 86.4-92.0/92.0=6% tax rate?! ditto. Top 1%: from 1-(448.3/666.8)= 33% to 1-(1535.3/2329.5) = 34%
happily the new CBO 2016 household income distribution is out! they have a great table builder function
so btw 1979 and 2016 for households in the lowest quintile with children went from 17,200 (Market Income) 19,200 (Before Taxes/Transfers) 25,700 (Net taxes/transfers) to 25,300 (Market) 27,300 (Before taxes/transfers) 48,900 (Net taxes/transfers)
households in the middle quintile with children went from 67,600 (Market Income) 69,100 (Before Taxes/Transfers) 55,700 (Net taxes/transfers) to 92,000 (Market) 95,700 (Before taxes/transfers) 86,400 (Net taxes/transfers)
for that same group/period for top 1% the numbers went from 666.800 (Market Income) 668,200 (Before Taxes/Transfers) 448,300 (Net taxes/transfers) to 2,329,500 (Market) 2,330,500 (Before taxes/transfers) 1,535,300 (Net taxes/transfers)
