Do household income figures understate gains in individual living standards?
Core argument: Census Bureau data show median household income per household member rose 86.6% since 1967, roughly double the 43.3% growth in real median household income over the same period.
The Census Bureau's recent report highlights a significant +86.6% increase in median household income per household member since 1967, nearly doubling the real median household income growth of 43.3%. This adjustment accounts for the decline in average household size over the decades, providing a more accurate reflection of economic progress. The data, adjusted to constant 2019 dollars, underscores the importance of considering household size when evaluating income growth. This nuanced understanding is crucial for economists and policymakers as it reveals a more substantial improvement in individual economic well-being than aggregate household income figures suggest. The findings emphasize the need for policies that address income distribution and household dynamics to ensure equitable economic growth.


Steve Comment: Re: CPI: I think Table C-1 answers your question. They have all the series converging this year. but if you use the initial CPI-U-RS measure from 2000($59,275) you’ve got an increase of16% (15.9) versus justunder 10% (9.9)if you use the adjusted$62,512as your baseline (all 2019 dollars) “…. show historical income adjusted using the C-CPI-U compared to the CPI-U-RS from 2000 onward. For 2000, the income estimate in 2019 dollars adjusted using the CPI-U-RS is $62,512, compared to $59,275 when adjusted using the C-CPI-U, a difference of 5.2 percent….”
Ed Comment:Of course being the propagandist they are they show the delay in the past rather the present. It's subtle keeps attention focused on "the top line." Using CPU what is the growth?
They built a nice chart showing outcomes by different adjustments using their current method (CPI-U-RS) and C-CPI-U and PCE (also in appendix):
Steve Comment:Census uses (it is in appendix C) CPI-U-RS, which is also the number Perry is citing.
Ed Comment:Income per family member overstates the gains. More interesting and closer to the truth would be income per adult family member. (could we get that? To court family members, they must have the data.) Although some adults don't have children so they can work less rather than to personally consuming more of their earnings.
He finds, “…The size of the average US household has declined steadily over time and fell to an all-time low last year of 2.52 members. That’s a decline of 0.76 household members since 1967 when the average US household size was 3.28 persons. On a percentage basis, that’s more than a 23% decline in the size of the average US household over the last 50 years…. We can adjust for the declining average household size by calculating the real median household income per household member, which almost doubled from $14,615 in 1967 to $27,263 last year. Over that same period, inflation-adjusted median household income increased by 43.3% from $47,938 in 1967 to $68,703 last year. That’s quite a difference — the percent increase in median household income per household member since 1967 of 86.6% is almost exactly twice the percent increase in real median household income over the last half-century of 43.3%....”
