A president has only limited control over the economy. And yet there has been a stark pattern in the United States for nearly a century. The economy has grown significantly faster under Democratic presidents than Republican ones.

It’s true about almost any major indicator: gross domestic product, employment, incomes, productivity, even stock prices. It’s true if you examine only the precise period when a president is in office, or instead assume that a president’s policies affect the economy only after a lag and don’t start his economic clock until months after he takes office. The gap “holds almost regardless of how you define success,” two economics professors at Princeton, Alan Blinder and Mark Watson, write. They describe it as “startlingly large.”

Since 1933, the economy has grown at an annual average rate of 4.6 percent under Democratic presidents and 2.4 percent under Republicans, according to a Times analysis. In more concrete terms: The average income of Americans would be more than double its current level if the economy had somehow grown at the Democratic rate for all of the past nine decades. If anything, that period (which is based on data availability) is too kind to Republicans, because it excludes the portion of the Great Depression that happened on Herbert Hoover’s watch.

The six presidents who have presided over the fastest job growth have all been Democrats, as you can see above. The four presidents who have presided over the slowest growth have all been Republicans.

The big question, of course, is why. And there are not easy answers.
