Adult Literacy |
The percentage of adults who can read and write with understanding. |
The global literacy rate for adults (age 15+) is about 86–87% worldwide. That means roughly 8 out of every 10 people can read and write a simple sentence. Male literacy rate: about 90%
Female literacy rate: about 83%
Around 739 million adults still lack basic literacy skills globally. |
| Demographic and Social |
Life expectancy |
The average age that a person is expected to live from birth. |
According to WHO, 72 years was the average life expectancy at birth of the global population. Life expectancy varies widely:
In many high-income countries, it is above 80 years
In some low-income or conflict-affected countries, it can be below 60 years.
The country with the highest life expectancy is Monaco at 87 years; followed by Japan, Singapore, Switzerland, Spain. The country with the lowest life expectancy is Chad around 49 years. These countries tend to have: Strong healthcare systems,
High living standards, Healthy diets,
Low violent crime rates. Global life expectancy has generally increased over the last century because of:
Better healthcare
Vaccinations
Improved sanitation
Better nutrition
Lower child mortality rates
High elderly care quality.
Women generally live longer than men in nearly every country. |
| Demographic and Social |
Infant mortality
Child mortality (under 5 years of age) |
The number of babies who don’t survive to the age of 1 (infant) per 1,000 live births. 60–80% of the infant mortality in developing countries are mostly caused by birth defects, preterm birth and low birth weight, maternal pregnancy complications. |
Afghanistan recorded the highest infant mortality rate in the world, with 111 deaths per 1,000 children 5 years old and younger. Accessing healthcare in Afghanistan is very difficult for pregnant women and young babies. Monaco, a small wealthy country in Europe records the lowest count with 1.8 because of its good healthcare system and woman education. |

GNI per capita |
Gross national income per person. The value of a country’s income, divided by the number of people in that country. |
Qatar has the world’s highest GNI per capita while Burundi and the Central African Republic have the lowest incomes out of any country in the world. Almost half of the world’s population live on less than $2.50 a day. |

Access to safe clean water |
The percentage of people who have access to safe, clean water for their day to day needs. |

| Social and demographic |
People per doctor |
the number of people per doctor. A lower ratio can indicate a richer country. |
Tanzania, Malawi, Niger and most of the LDCs in Africa has the lowest number of doctors per 1000 (less than 2 doctors per 100,000 people). The UK has fewer doctors per head of population than most other countries in OECD. |
| Economic and social |
Unemployment rate |
People as a percentage of the labour force those who are willing and available to work, but not getting a job for their qualification. |
Syria at present has the highest unemployment rate at 50%. The continent of Africa registers the higher average unemployment rate of more than 20%. Most of the developed countries register below 10% unemployment rate. There are just two nations Cambodia and Thailand with unemployment rates of less than 1%, mainly because of the self employed informal sector job. |

Internet penetration rate |
Percentage of the population having access to telecommunication network and technology infrastructure |
About 74% of the world’s population has access to and uses the internet as of 2025. That equals roughly 6 billion people online worldwide.
That also means around 26% of people (about 2.2 billion) are still offline globally. Access varies a lot by region:
Higher-income countries often exceed 90% internet penetration
Some low-income countries are still below 30%. In North Korea, internet access is extremely limited. Estimates suggest that fewer than 1% of the population has access to the global internet. Most ordinary citizens cannot freely use the internet at all. Instead, many people who use digital networks access a government-controlled intranet called Kwangmyong, which is separate from the global internet and heavily monitored. |
