I’m a little late to this, but petty gotchas are always worth airing even if they aren’t on time. I would like you to cast your memories back to February 28, when the initial GDP report for 2018 was released. Sadly for President Trump, it showed GDP growth of 2.9 percent, just below his promised goal of 3 percent. But no problem! The White House simply used a different measure of GDP growth and insisted that it was the correct one:

How did they get 3.1 percent growth? Normally, you measure GDP growth year over year. That is, you calculate GDP in 2017 and GDP in 2018 and then divide to get the growth rate. But the Trumpies instead compared Q4 of 2018 to Q4 of 2017. Nobody ever does it this way, but any port in a storm. It produced the number they wanted, so they insisted this was the right way to measure it.

But Friday brought bad news. Apparently Q4 growth was a lot worse than we thought. Using the final GDP numbers, here’s what we get:

Oof. Growth was only 2.5 percent in 2018. This is the White House’s own preferred measure of economic growth, so I suppose they’ll just have to accept it. That goes for Fox News and everyone else, too. I’m sure their intellectual standards are too high to simply deny they ever used this metric and stick to their old numbers.

UPDATE: I orginally said the White House “invented” a new measure of GDP. That went too far. They simply chose to emphasize a measure that made them look as good as possible.

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.
