Q4 Real GDP Per Capita: 1.40% Versus The 2.08% Headline Real GDP

The Advance Estimate for Q4 GDP came in at 2.1% (2.08% to two decimals), essentially unchanged from 2.1% (2.12% to two decimals) in Q3. With a per-capita adjustment, the headline number is lower at 1.40% to two decimal points.

Here is a chart of real GDP per capita growth since 1960. For this analysis, we've chained in today's dollar for the inflation adjustment. The per-capita calculation is based on quarterly aggregates of mid-month population estimates by the Bureau of Economic Analysis, which date from 1959 (hence our 1960 starting date for this chart, even though quarterly GDP has is available since 1947). The population data is available in the FRED series POPTHM. The logarithmic vertical axis ensures that the highlighted contractions have the same relative scale.

The chart includes an exponential regression through the data using the Excel GROWTH function to give us a sense of the historical trend. The regression illustrates the fact that the trend since the Great Recession has a visibly lower slope than the long-term trend. In fact, the current GDP per-capita is 7.6% below the pre-recession trend.

GDP per Capita Linear

The real per-capita series gives us a better understanding of the depth and duration of GDP contractions. As we can see, since our 1960 starting point, the recession that began in December 2007 is associated with a deeper trough than previous contractions, which perhaps justifies its nickname as the Great Recession.

Quarterly GDP Compounded Annual Rate of Change

The standard measure of GDP in the US is expressed as the compounded annual rate of change from one quarter to the next. The current real GDP is 2.08%. But with a per-capita adjustment, the data series is lower at 1.40%. The 10-year moving average illustrates that US economic growth has slowed dramatically since the last recession.

Year-Over-Year GDP and Recession Risk

Economists and financial journalists vary widely in their opinions about the current level of recession risk. The official call on recessions, of course, is the domain of the National Bureau of Economic Research, which makes the determination on recession start and end several months — sometimes more than a year — after the fact.

GDP per capita, as we've seen, is a weaker series than GDP. What does it suggest about our current recession risk? The next chart shows the YoY change in real GDP per capita since 1960. We've again highlighted recessions. The red dots show the YoY real GDP for the quarter before the recession began, and the dotted line gives us a sense of how the current level compares to recession starts since 1960. This chart suggests that, despite chronic weakness in the economy, this indicator is not recessionary. That said, we must remember that GDP is a heavily revised lagging indicator.

Year-over-Year

The current YoY at 1.46% is above the 1.32% average value of the eight recession starts in the chart above with one exception — the second and more painful half of the early 1980's double dip. That recession was an outlier in that it was to some extent knowingly engineered by the Fed (then-Chairman Paul Volcker ), an inevitable side-effect of raising the Fed Funds Rate north of 19% to break the back of the stagflation of the era.

How do the two compare YoY series compare, GDP and GDP per capita? Here is an overlay of the two in the 21st century.

since 2000

To expand on the illustration above: Since 1959 mean (average) GDP is 3.2 percent. Mean GDP per capita is 2.0 percent. Again, we must remember that GDP is a heavily revised lagging indicator.
