Declining US birthrates

There’s a hypothesis that there are environmental and biological reasons, for the decline in US birthrates.

In a press release, the lead author of a recent meta-analysis suggested that among men in the U.S. with no known fertility challenges, “sperm counts are largely stable and haven’t changed significantly” in recent years. Moreover, it’s unclear whether sperm quality has declined. According to a 2022 review published in Nature Reviews Urology, researchers have observed a trend in some geographic areas, but available data doesn’t indicate that semen quality is necessarily deteriorating worldwide or in the Western world.

In other words, inconclusive.

But what is true and conclusive is that it’s really expensive in the United States to raise a child.
