Low fertility may not be an economic threat, researchers argue

In their piece, published in Nature Human Behaviour, IIASA Distinguished Emeritus Research Scholar Wolfgang Lutz and IIASA Senior Researcher Guillaume Marois, who is also an associate professor at the Asian Demographic Research Institute of the Shanghai University, respond to political and public concern over declining birth rates in highly developed countries. While low fertility is increasingly framed as a crisis, associated with population aging, labor shortages, and fiscal pressure, the authors argue that this narrative is based on outdated assumptions that no longer reflect current demographic realities.
