The Coming Democratic Baby Bust
February 17, 2025
Donald Trump’s first term saw a great deal of political polarization. Right- and left-leaning Americans disagreed about environmental regulation and immigration. They disagreed about vaccines and reproductive rights. And they disagreed about whether or not to have children: As Republicans started having more babies under Trump, the birth rate among Democrats fell dramatically.
A few years ago, Gordon Dahl, an economist at UC San Diego, set out to measure how Trump’s 2016 victory might have affected conception rates in the years following. And he and his colleagues found a clear effect: Starting after Trump’s election, through the end of 2018, 38,000 fewer babies than would otherwise be expected were conceived in Democratic counties. By contrast, 7,000 more than expected were conceived in Republican counties in that same period. (The study, published in 2022, was conducted before data on the rest of Trump’s term were available.) Over the past three decades, Republicans have generally given birth to more kids than Democrats have. But during those first years of the first Trump administration, the partisan birth gap widened by 17 percent. “You see a clear and undeniable shift in who’s having babies,” Dahl told me.
