Declining Fertility Rates and the Future of Healthcare Systems

Famey Lockwood · May 13, 2026

Declining fertility rates are not just demographic trends — they are reshaping healthcare systems, workforce dynamics, and global future care needs.

"Our World in Data" recently published research examining the global decline in fertility rates, with long-term implications for societies, countries, and individuals worldwide.

Birth rates are falling globally

The data shows that the global fertility rate — the average number of children born per woman — has fallen dramatically over the past sixty years. Historically, women had an average of about five children throughout much of the world. Since the mid-1960s, the global fertility rate has dropped by half, to fewer than 2.5 children per woman today.

Three major reasons for the decline (per the study):

The empowerment of women — including increased access to education, contraception, and labor market participation
Declining rates of child mortality and higher standards of living
Rising costs of raising children — more children mean higher cost to families, and the decline of child labor reduces income for families

What this means for health systems

Fewer births combined with an aging population will require significant restructuring of healthcare systems
Demand for maternal and pediatric services may decrease for some populations
An aging population brings increasing growth in chronic diseases and geriatric care needs
An aging population will require more elder care
Longer patient lifecycles will generate increasingly complex longitudinal health records and data needs

Are health systems structured for this shift?

With an aging population and fewer new generations to care for it, will this create a crisis for healthcare — or will AI be a welcomed and meaningful solution? AI may become an important support tool for increasingly strained health systems through predictive analytics, workflow automation, clinical decision support, and longitudinal population health management.

Where health information systems and HI professionals become essential:

Interoperability across care settings becomes imperative (FHIR, HL7)
Secure and effective health data sharing is non-negotiable
Longitudinal health data management across the lifespan
Predictive analytics for aging populations becomes essential

Where do you fit in — with your career, your lifestyle, your family? Declining fertility rates are not just demographic trends — they are reshaping healthcare systems, workforce dynamics, and global future care needs.
