With the perception swelling that he will be the Republican nominee, Mitt Romney has increasingly moved his attention away from his party rivals to President Barack Obama.
On Jan. 16, 2012, Romney sent a tweet blasting Obama for his jobs record.
"More Americans have lost their jobs under Barack Obama than any president in modern history," Romney wrote.
Several readers asked us to check it out.
First, we should mention that there is no useful statistic for "Americans (who) have lost their jobs" during a given time period. The labor force is fluid, so people who lose their jobs often move quickly into another one. Instead, economists use the concept of net jobs gained or lost -- how many more (or fewer) people were employed on Date B than on Date A.
When we asked the Romney campaign for backup material, they confirmed that they were talking about net jobs lost under a given president. So that’s the measure we used.
We found that Obama is indeed the only president to have a net job loss if you count from inauguration day until the end of the presidency. But it’s not necessarily fair to credit or blame presidents for jobs created or lost during the first year on the job, since the president’s policies have not had time to take effect.
Instead, if you start the count at one year into a president's term and end it one year -- a somewhat arbitrary method, but a defensible one -- it turns out that the Obama administration has presided over a net increase in jobs. So using this method, the premise of the Romney claim -- that the net jobs change for the nation as a whole under Obama was negative -- evaporates. In fact, using this method means that Obama’s predecessor, George W. Bush, becomes the only president to lose jobs on his watch.
Let’s dig deeper into the numbers.
The numbers starting at inauguration day
As we noted, the numbers provided by the Romney campaign used jobs figures for the president’s first and last days in office. To replicate the campaign's math, we turned to the Bureau of Labor Statistics, the federal agency that tracks employment figures going back decades. Due to BLS data constraints and Romney’s use of the term "modern" presidents, we limited our search to presidents from Harry Truman on.
In previous fact checks, we’ve tried to adjust for the time each president has spent in office. But since the Romney tweet was clear about referring to total numbers of people who lost jobs, rather than the rate at which people were losing jobs under each president, we did not take that additional step for this item.
We first calculated how many jobs were gained or lost during each president’s tenure on a net basis. We also tried to adjust for the size of the population by dividing the net job gain or loss by the nation’s estimated population during the president’s first year in office. (Comparing jobs gained or lost under Obama, when the U.S. population is more than 300 million, to the changes under Truman, when the population was below 140 million, is comparing apples and oranges.)
In this chart, the first number refers to the net jobs gained or lost during the president’s tenure starting at the very beginning of his term, and the second number refers to the net change in jobs as a percentage of the U.S. population. The presidents are listed in descending order by most jobs created:
1. Bill Clinton + 22,744,000 +8.8 percent of population
2. Ronald Reagan + 16,102,000 +7.0 percent of population
3. Lyndon B. Johnson + 12,183,000 +6.3 percent of population
4. Jimmy Carter + 10,339,000 +4.7 percent of population
5. Richard Nixon + 9,181,000 +4.5 percent of population
6. Harry Truman + 8,083,000 +5.8 percent of population
7. John F. Kennedy + 3,538,000 +1.9 percent of population
8. Dwight Eisenhower + 3,572,000 +2.2 percent of population
9. George H.W. Bush + 2,592,000 +1.1 percent of population
10. Gerald Ford + 2,073,000 +1.0 percent of population
11. George W. Bush + 1,094,000 +0.4 percent of population
12. Barack Obama - 1,663,000 -0.5 percent of population
So by this measure, Romney is right: Obama is the only president who saw a net job loss during his presidency. This means it’s reasonable for him to say that "more Americans have lost their jobs under Barack Obama than any president in modern history."
But, as we noted, that’s not the only way to look at it.
