The last two decades have seen significant progress in global health. Life expectancy has risen significantly, from 66.8 to 73.4 years, a remarkable gain of 6.6 years.
However, the second decade (2010-2020) saw a slowdown in health progress, raising concerns about its universality and sustainability. Progress is unevenly spread across countries and populations, and its reversibility is a constant concern.
The document is divided into four sections: demographic issues, major trends in communicable and non-communicable diseases, the impact of the climate crisis on health, and a review of the current state of universal health coverage worldwide.
This « diagnosis » offers a synthesis of two decades of global health change. This analysis is not intended to be exhaustive, but rather to offer a global vision of the main trends, and to highlight the progress made over these two decades, in order to better identify the gaps, the margins for progress, and the warning points that call into question some of the advances made. We wanted to bring together scattered data, too often analyzed « in silo », by theme, to bring them into dialogue and lay the foundations for a more global reflection on global health issues.
