  • U.S. fertility rates are at an all-time low, partially due to delayed parenthood, increased childlessness, fewer unplanned teenage pregnancies, and declines in immigration. As explained by Hans-Peter Kohler, Pilar Gonalons-Pons, and Emilio Alberto Parrado in Penn Today, the drop isn’t cause for alarm but does bring to light questions about work, family, and immigration policies that can affect population growth.

  • Hans-Peter Kohler, PSC & PARC research associate, discusses the recent decline in U.S. birth rates on a Marketplace podcast. “At the level we are observing it in the U.S., it is not a problem. If the U.S. had South Korean, Japanese, or Italian fertility rates, arguably, the pressure to do something about this might be higher,” says Kohler.

  • PSC researcher, Hans-Peter Kohler, was quoted in a Washington Post article about his work on fertility, birthrates, and the shift in US birthrates among teens and young adults.
