Global R&D spending as a share of GDP
% of GDP
A share of output, not an absolute spending total.
Thirty ways to look at research, invention, health, infrastructure and the gaps that remain.
Explore 30 charts ↓Scientific work matters, but a graph of an outcome cannot assign credit to a single person. Discoveries meet technicians, nurses, engineers, teachers, institutions, public funding and policy before they reach everyday life.
Every chart gives its unit, time frame and source. Some figures are estimates or rounded values; the captions identify derived and illustrative numbers.

% of researchers
A small increase; representation remains unequal.
Patent applications filed worldwide
millions of applications
Filing is not the same as an invention being valuable.
Share of global patent applications
% of filings
Region of the receiving patent office, not inventors’ birthplace.
Five largest patent offices vs all others, 2024
% of applications
Share of filings at offices, not a distribution of scientific talent.
Computer technology vs other fields, 2023
% of published patents
Technology classification of published applications.
Applications received by three offices, 2024
thousands of applications
China figure rounded to 1.8 million by WIPO; these are receiving offices, not applicants’ origins.
People using the internet worldwide
billions of people
Rounded estimates.
Worldwide internet use, 2025
% of people
Rounded percentages; offline share derived as 100 − 74.
People not using the internet worldwide
billions of people
Rounded estimates.
Internet use, 2025
% of population
National income groups; internet access and use are distinct.
Countries with endemic wild poliovirus
countries
1988 is over 125; plotted at 125 as a conservative floor.
Wild poliovirus cases relative to the 1988 baseline
1988 index = 100
Illustrative upper bound: WHO states a decline of over 99%; .99 is below 1, not an exact present count.
Nurses worldwide
millions of nurses
Reported figures from the linked primary source.
Estimated global nursing shortage
millions of nurses
Shortage estimates, not a count of vacant job postings.
Countries containing 78% of nurses, 2023
% of world total
The same set of countries contains 49% of the world population.
Maternal deaths per 100,000 live births
deaths / 100,000 births
Global estimates; many causes and policies contribute.
Global life expectancy at birth
years
2021 estimate from WHO’s 2024 release; COVID-19 reversed progress.
Under-five mortality, approximate indexed change
1990 index = 100
2024 index is an approximation derived from UNICEF’s statement that the rate fell about 60%.
Global DTP vaccine coverage, 2024
% of infants
DTP = diphtheria, tetanus and pertussis.
People lacking safely managed services, 2024
billions of people
Different indicators; people may appear in more than one group.
Global measles vaccine coverage, 2024
% of children
Global estimates; these percentages describe vaccine coverage, not efficacy.
Safely managed sanitation, worldwide, 2022
% of people
43% is the complement; it includes several service levels.
Global renewable power capacity added
gigawatts added
2023 figure also documented by IRENA’s 2024 release.
Share of new global power capacity that was renewable, 2024
% of additions
IRENA reports over 90%; 90/10 is a conservative illustrative boundary.
Atmospheric CO₂ concentration
parts per million
Approximate preindustrial baseline. This depicts a harmful trend, not a benefit of innovation.
A qualitative map of collective contribution
sequence
Conceptual diagram, not numerical evidence or a claim that one person caused an outcome.
These graphs track outcomes and access. They cannot show every contributor or settle what a life is worth.
