Fertility and Voting Patterns

November 1, 2007

Does fertility affect voting patterns? Apparently it does much more than we realize. And this has been a topic of discussion for both liberals and conservatives, Democrats and Republicans.

Arthur Brooks wrote a significant op-ed on the “Fertility Gap” last year in the Wall Street Journal. He said: “Simply put, liberals have a big baby problem: They’re not having enough of them . . . and their pool of potential new voters is suffering as a result.”

He noted that “if you picked 100 unrelated politically liberal adults at random, you would find that they had, between them, 147 children. If you picked 100 conservatives, you would find 208 kids.” That is a “fertility gap” of 41 percent.

We know that about 80 percent of people with an identifiable party preference grow up to vote essentially the same way as their parents. This “fertility gap” translates into lots more little Republicans than little Democrats who will vote in future elections.

So what could this mean for future presidential elections? Consider the key swing state of Ohio which is currently split 50-50 between left and right. If current patterns continue, Brooks estimates that Ohio will swing to the right and by 2012 will be 54 percent to 46 percent. By 2020, it will be solidly conservative by a margin of 59 percent to 41 percent.

Now look at the state of California that tilts in favor of liberals by 55 percent to 45 percent. By the year 2020, it will be swing conservative by a percentage of 54 percent to 46 percent. The reason is due to the “fertility gap.”

Of course most people vote for politicians, personalities, and issues not parties. But the general trend of the “fertility gap” cannot be ignored especially if Democrats continue to appeal to liberals and Republicans to conservatives.
