Global Health brings together indicators that explain why people get sick and what helps them recover—from childhood immunization and safer water to infection, alcohol-related harm, and antimicrobial resistance. It also shows where the burden is greatest and how it varies across communities, including the role of health-system capacity, workforce shortages, and out-of-pocket costs. Explore how financing, humanitarian support, and digital and medical solutions like mHealth, telehealth, and devices connect to outcomes.

Interpretation
Funding & Spending Interpretation
For the Funding and Spending picture, global health investment remains vast but uneven because per person spending was US$31.1 billion in 2021, total development assistance for health reached US$52.0 billion in 2022, yet humanitarian nutrition aid was only US$1.6 billion in 2022.

Interpretation
Health Systems Interpretation
Health systems face mounting pressure as projected shortfalls of 5.9 million health workers by 2030, combined with heavy financial burdens like 15% of the world’s population spending over 10% of household costs out of pocket on health, threaten progress even while many countries still lag on key planning such as only 62% having functional national cancer control plans in 2022.
