No, says
Martin Feldstein.
But first, 10% of economists surveyed strongly agreed with the following statement and 50% agreed:
The 9% cumulative increase in real US median household income since 1980 substantially understates how much better off people in the median American household are now economically, compared with 35 years ago.

Excerpts from Martin Feldstein:
"it
is frequently said that the average household income has risen only
slightly, or not at all, for the past few decades. Some US Census
figures seem to support that conclusion. But more accurate government
statistics imply that the real incomes of those at the middle of the
income distribution have increased about 50% since 1980. And a more
appropriate adjustment for changes in the cost of living implies a
substantially greater gain.
The US Census Bureau
estimates the money income that households receive from all sources and
identifies the income level that divides the top and bottom halves of
the distribution. This is the median household income. To compare median
household incomes over time, the authorities divide these annual dollar
values by the consumer price index to create annual real median
household incomes. The resulting numbers imply that the cumulative
increase from 1984 through 2013 was less than 10%, equivalent to less
than 0.3% per year.
Any adult who was
alive in the US during these three decades realizes that this number
grossly understates the gains of the typical household. One indication
that something is wrong with this figure is that the government also
estimates that real hourly compensation of employees in the non-farm
business sector rose 39% from 1985 to 2015.
The official Census
estimate suffers from three important problems. For starters, it fails
to recognize the changing composition of the population; the household
of today is quite different from the household of 30 years ago.
Moreover, the Census Bureau’s estimate of income is too narrow, given
that middle-income families have received increasing government
transfers while benefiting from lower income-tax rates. Finally, the
price index used by the Census Bureau fails to capture the important
contributions of new products and product improvements to Americans’
standard of living.
Consider first the
changing nature of households. From 1980 to 2010, the share of
“households” that consisted of just a single man or woman rose from 26%
to 33%, while the share that contained married couples declined from 60%
to 50%.
When the nonpartisan Congressional Budget Office
(CBO) conducted a
detailed study
of changes in household incomes from 1979 to 2011, it
expanded the
definition of income to include near-cash benefits like food stamps and
in-kind benefits like health care. It also
subtracted federal taxes,
which fell from 19% of pretax income for middle-income households in
1980 to just 11.5% in 2010. To convert annual incomes to real incomes,
the
CBO used the price deflator for consumer expenditures, which many
believe is better for this purpose than the consumer price index. The
CBO also presented a separate analysis that
adjusted for household size.
With
the traditional definition of money income, the CBO found that real
median household income rose by just 15% from 1980 to 2010, similar to
the Census Bureau’s estimate. But when they expanded the definition of
income to include benefits and subtracted taxes, they found that the
median household’s real income rose by 45%. Adjusting for household size
boosted this gain to 53%. And, again, even this
more substantial rise probably represents a substantial underestimate
of the increase in the real standard of living. The authorities arrive
at their estimates by converting dollar incomes into a measure of real
income by using a price index that reflects the changes in the prices of
existing goods and services. But that price index does not reflect new
products or improvements to existing goods and services.
Thus, if everyone’s
money incomes rose by 2% from one year to the next, while the prices of
all goods and services also rose by 2%, the official calculation would
show no change in real incomes, even if new products and important
quality improvements contributed to our wellbeing. Indeed, the US
government does not count the value created by Internet services like
Google and Facebook as income at all, because these services are not
purchased.
No one knows how much
such product innovations and improvements have added to our wellbeing.
But if the gains have been worth just 1% a year, over the past 30 years
that would cumulate to a gain of 35%. And combining that with the CBO
estimate of a gain of about 50% would imply that the real income of the
median household is up nearly 2.5% a year over the past 30 years."
