The Myth of Slow Growth Revisited

Was economic growth in the period 1950-80 really significantly higher than it has been in the period since then? Yesterday I said that growth rates in those two periods were actually about the same, and today Stuart Staniford and Ryan Avent say I’m wrong. They both have a point, so let’s revisit this.

Stuart points out that a 100-year logarithmic chart hides small differences. Ryan points to decadal averages for real GDP. So here’s a new chart that addresses both of these concerns (GDP and population data from FRED.):

First off, I’m using GDP per capita, not raw GDP, since that’s a better measure of actual economic growth. Stuart suggests that GDP per working-age person might be a better measure, and I’m open to that depending on what it is we want to measure. Still, GDP per capita is the usual measure, so that’s what I used.

The most obvious conclusion that pops out from the data is that growth has been fairly steady for the past sixty years with the exception of a nice growth spurt in the mid-60s. You can see that in the average growth rates per decade:

  • 1950s: 1.67%
  • 1960s: 3.42%
  • 1970s: 2.49%
  • 1980s: 2.43%
  • 1990s: 2.02%
  • 2000s: 1.27% (through 2007)

For the 30-year period 1950-79, growth averaged 3.18%. For the 28-year period 1980-2007, growth averaged 2.53%.

There are a couple of conclusions here. (1) The 60s were great, the 2000s were lousy. (2) Overall growth in the most recent three decades was indeed lower than in the three decades of the postwar era. (3) But not by a lot.

So I overstated things yesterday, but I’d still say it’s the economy of the aughts that’s a problem, not the entire post-70s era. The fact is that the post-70s economy as a whole simply wasn’t a lot worse than the post-40s economy. The problem during this era wasn’t primarily that growth was lackluster, it’s that middle class wages consistently lagged growth by upwards of a percentage point per year.

So to revisit yesterday’s point: yes, growth is important. You can’t have 2% wage growth if the economy is growing 1.27% per year. But it’s not enough. We had good growth for three decades after the end of the 60s and it didn’t produce steady middle-class income gains. Distribution is important too. 

HERE ARE THE FACTS:

Our fall fundraising drive is off to a rough start, and we very much need to raise $250,000 in the next couple of weeks. If you value the journalism you get from Mother Jones, please help us do it with a donation today.

As we wrote over the summer, traffic has been down at Mother Jones and a lot of sites with many people thinking news is less important now that Donald Trump is no longer president. But if you're reading this, you're not one of those people, and we're hoping we can rally support from folks like you who really get why our reporting matters right now. And that's how it's always worked: For 45 years now, a relatively small group of readers (compared to everyone we reach) who pitch in from time to time has allowed Mother Jones to do the type of journalism the moment demands and keep it free for everyone else.

Please pitch in with a donation during our fall fundraising drive if you can. We can't afford to come up short, and there's still a long way to go by November 5.
