Universal health coverage (UHC) means all people can access quality essential health services without financial hardship — the foundational goal of SDG 3.8 (WHO). The 2023 UN Political Declaration on UHC set a target for 80% of the world's population covered by essential services by 2030. Yet 4.5 billion people remain without full essential health coverage and financial hardship from health spending affects 2 billion. Primary health care is the most cost-effective route to UHC.

Key messages

Scale of unmet need
At least 4.5 billion people — more than half the world's population — lack access to essential health services. This is the defining health equity challenge of our time (WHO/World Bank 2023).
Financial protection gap
At least 2 billion people face financial hardship when they use health services. 1 billion are pushed into extreme poverty each year by out-of-pocket health spending.
SDG 3.8
Universal health coverage is at the heart of SDG 3 — SDG 3.8 targets access to quality essential health services and financial risk protection for everyone by 2030.
What UHC means
UHC means all people can obtain health services they need — promotion, prevention, treatment, rehabilitation and palliation — of sufficient quality, without financial hardship.
Primary health care is the foundation
UHC cannot be achieved without strong, people-centred primary health care. The 2018 Astana Declaration reaffirmed PHC as the most effective pathway to UHC.
Progress stalled
UHC progress as measured by the Service Coverage Index stalled from 2015 onward, worsened by COVID-19. The annual financing gap to achieve UHC in LMICs is estimated at $371 billion (World Bank).
