Research reveals widening gap in fertility desires between Republicans and Democrats
The magazine Utne Reader published an article on this about 20 years ago. Republicans have larger families and outbreed Democrats. I am a lefty, and showed it to my husband because I wanted us to have a third child. He remained unmoved. Luckily, once children from Republican families grow up, move away and get educated, many of them become Democrats. Which is one reason Republicans hate education. The more educated you are, the more likely you are to vote Democratic. https://www.pewresearch.org/politics/2016/04/26/a-wider-ideological-gap-between-more-and-less-educated-adults/ More on reddit.com

May 25, 2022 - The use of state controls (and some robustness tests I ran in large states with many counties) suggests this effect isn’t driven by unique features of states: within Red states or Blue states, and controlling for county racial and ethnic characteristics and population densities, Republican counties have higher birth rates. This is particularly astonishing given that Democrats perform very well in counties with many Hispanic and black voters, who have higher birth rates than non-Hispanic white Americans (and indeed, the more non-Hispanic whites in a county, the lower its birth rate in my models).

Democrats seize shared parenting issue as Republicans back away from it | Fox News
The unexplainable part is the Republicans giving Democrats the opening. Shared parenting gives fathers fair treatment, which seems a natural Republican issue. The GOP also has traditionally supported parents’ rights issues such as school choice. Is it because the most vocal shared parenting opponents are attorneys’ associations and the GOP is giving in to a special interest group? ... Shared parenting is good for everyone, no matter their party. Since its landmark law, Kentucky has seen total divorce filings decline and family court domestic violence cases in particular plummet. Its 11 exceptions to the shared parenting presumption have helped child maltreatment decline since the bill passed. So which way will the parties go? Charlie Kirk's last group of social media posts recommended both parties champion shared parenting. If polling and voting patterns keep growing for shared parenting, the parties won’t have any other choice.

Right-wing media target pregnant and female travelers following SCOTUS birthright citizenship ruling | Media Matters for America
Pundits suggested refusing pregnant travelers visas, deporting “birthing-aged” women, and even sterilizing travelers entering the United States ... After the Supreme Court upheld birthright citizenship, right-wing media proposed draconian policies to prevent travelers potentially giving birth in the United States. The policies demanded by right-wing media — which almost exclusively target female migrants — were often proposed under the guise of combating birth tourism, which the U.S. already has enforcement tools in place to prevent. On June 30, the Supreme Court rejected President Donald Trump’s attempt to end birthright citizenship. On the first day of Trump’s second term, the president signed an executive order seeking to deny birthright citizenship to the children of undocumented immigrants and the children of those in the country legally on temporary work, student, or tourism visas.

The Trump Bump: The Republican Fertility Advantage in 2024 | Institute for Family Studies
December 19, 2024 - Finally, Patrick T. Brown noted in an earlier IFS blog post that Republican counties do not significantly differ from Democratic counties in the proportion of babies born to married parents, contrary to years past. So, while Republican counties have higher fertility rates, these babies are not necessarily being born into more stable families. Nonetheless, the growing fertility divide has important political implications. Republicans live in areas where families are larger, and where more voters would directly benefit from policies like the Child Tax Credit.

Answer (1 of 7): Republicans say that they would like the birth rate to be higher, but they’re not trying to do anything that would ensure a good quality of life if Americans bring more kids into the world. Democratic leaders haven’t said that they wouldn’t like the birth rate to be higher.
