TIMELY, RELIABLE DATA ON GLOBAL HEALTH FINANCING AND SPENDING

Key findings from FGH 2021


Total global health spending in 2019

$9.2 trillion

This includes spending by governments, individuals, private companies, and development agencies, and represents a 3.1% increase from the year before.


Government health spending

59.8% of total 

Spending on health from all levels of government, in public and private facilities. 


Prepaid private spending

21.5% of total

Spending from insurance companies directly to the health system (does not include premium payments or insurance company profits). 


Out-of-pocket spending

18.2% of total

Out-of-pocket spending includes payments from individuals directly to the medical system, not paid in advance. 


Development assistance for health (DAH)

0.5% of total

Support provided through major development agencies to improve and maintain health in low- and middle-income countries.

HUMAN DEVELOPMENT REPORT 2021-22

This new uncertainty complex and each new crisis it spawns are impeding human development and unsettling lives the world over. In the wake of the pandemic, and for the first time ever, the global Human Development Index (HDI) value declined—for two years straight. Many coun­tries experienced ongoing declines on the HDI in 2021. Even before the pandemic, feelings of insecurity were on the rise nearly everywhere. Many people feel alienated from their political systems, and in another reversal, dem­ocratic backsliding has worsened.
There is peril in new uncertainties, in the insecurity, polar­ization and demagoguery that grip many countries. But there is promise, too—an opportunity to reimagine our futures, to renew and adapt our institutions and to craft new stories about who we are and what we value. This is the hopeful path forward, the path to follow if we wish to thrive in a world in flux.

When Does the Brain Operate at Peak Performance?

Column by JOHN M. BEGGS; Video by EMILY BUDER

The critical brain hypothesis suggests that neural networks do their best work when connections are not too weak or too strong.

Strong and Elusive
A new theoretical model explains the strange observations made in a 2017 particle physics experiment, reports Allison Parshall for Scientific American. The phenomenon can be explained by accounting for small-distance fluctuations in the strong force. Interactions involving the strong force are notoriously difficult to calculate. In 2022, Charlie Wood wrote for Quanta about recent progress in calculating and experimentally probing “nature’s most inscrutable force.”


Trying to Even the Odds
In 2006, the statistician Richard Gill discovered that flawed statistical methods had resulted in the wrongful conviction of a nurse. After a retrial, the nurse was released. To help prevent such miscarriages of justice in the future, Gill has now written guidelines on how to use statistics in court, writes Cathleen O’Grady for Science. Like Gill, the computer scientist Rediet Abebe pays attention to how mathematics can be a tool of injustice. In 2021, she spoke about how she uses algorithms to fight social inequity to Rachel Crowell for Quanta. You can also hear Rediet Abebe in conversation with Steven Strogatz on an episode of “The Joy of x” podcast from 2021.
