Real Disposable Income Per Capita In August

With the release of Friday’s report on August Personal Incomes and Outlays, we can now take a closer look at “Real” Disposable Personal Income Per Capita.

At two decimal places, the nominal 0.26% month-over-month change in disposable income was trimmed to 0.15% when we adjust for inflation. This is down up from the 0.26% and 0.09% increases MoM, respectively. The year-over-year metrics are 4.48% nominal and 2.21% real.

Post-recession, the trend was one of steady growth, but generally flattened out in late 2015. Things seem to have picked up slightly in 2018.

The first chart shows both the nominal per capita disposable income and the real (inflation-adjusted) equivalent since 2000. This indicator was significantly disrupted by the bizarre but predictable oscillation caused by 2012 year-end tax strategies in expectation of tax hikes in 2013. It will be interesting to see how the recent tax legislation affects the trend over time.

The BEA uses the average dollar value in 2009 for inflation adjustment. But the 2009 peg is arbitrary and unintuitive. For a more natural comparison, let’s compare the nominal and real growth in per-capita disposable income since 2000. Do you recall what you were doing on New Year’s Eve at the turn of the millennium? Nominal disposable income is up 85.6% since then. But the real purchasing power of those dollars is up only 32.3%.

DPI Per Capita

Let’s take one more look at real DPI per capita, this time focusing on the year-over-year percent change since the beginning of this monthly series in 1959. The chart below highlights the value for the months when recessions start to help us evaluate the recession risk for the current level.

The current YoY of 2.21% is above the 1.66% average YoY at the start of the eight recessions since 1959. Check out the conspicuous tax planning blips as well as Microsoft’s big dividend payout in 2004.

Consumption versus Savings

The US is a consumer-driven economy, as is evident from the percent share of GDP held by Personal Consumption Expenditures.
