Current World Population (2020, December 04)
This page features the world population data by country with live calculation based on the birth/death ratio. Whilst every effort is made to ensure the population information is correct and up to date, there may be changes which we are not aware of.
World population detail information update (Apr 2017)
As of April 24, 2017, the world population was estimated to have reached 7,500,000,000 according to United Nation. The report said population would increase by 11.2 billion in the year 2100. It is observed that there is a continuing s growth since the end of the Black Death and great famine which claimed almost 370 million lives all over the world from years 1315-1350.
The seventh fold growth in a span of 200 years has been driven because of the increasing numbers of people surviving the reproductive age, accompanied by the changes in fertility rates, the total annual births were highest in the late 1980s at about 139 million and continued to be constant until 2011. The trend changes the fertility rates and life expectancy, like in 1970s women had an average of 4.5 children each, but in 2014, total fertility rate had fallen to around 2.5 children per women. In the meantime, the average global lifespan have risen from 64.8 years in the early 1990s to 70.0 years today.
The huge increase in world population over the years is mainly the result of advancement in modern medicine and improvement in living standard. Information dissemination about life and birth also contribute to the increase. These have appreciably reduced or lessen infant death, child and maternal mortality. Modern medicine and medical technology also contribute to longer life expectancy.
Top most populous countries
There is a tremendous growth of population for the past centuries. According to world statistics, the following counties have the most number of populations.
As we can see on data six most populated counties are in Asia lead by China as the most populated nation. The other 5 nations are India, Indonesia, Pakistan, Bangladesh and Japan. The growth in the region started in the 1950s after the Second World War. All other countries are represented by only one country such as the USA (North America), Brazil (South America), Russia (Europe), and Nigeria (Africa).
Ten least Populous Countries
If we have the most populous nations, nevertheless, there are also countries with very small number of people living there. That if not in the news, we are not aware they exist. Mentioning the name to average person in the street, they would say they never heard of it.
Holy See (Vatican City)
Saint Kitts and Nevis
There are factors that contribute to why these countries mentioned above have least population. Most of them are isolated; they are just a small island that is difficult to reach because it its geographic location. Most of the island in the West Indies and the Caribbean has small population because it has small land mass. Some of this countries also has harsh weather, thus people living there tend to transfer to more secure places.
Ten most densely populated countries (people per sq km)
To determine the human density of a given city, town, or country, we have to get the sum of inhabitants in a given square area measured in square kilometer or square miles. In the past, there are large population and normally clustered around water sources, but today human density is great in countries where migration is allowed.
Country or City
Gibraltar (British Possession)
Countries with highest human population density in the world today face many problem, traffic congestion and air pollution is the most concern. Land Scarcity and water problem have increased as well. There are also high prices on sale of houses and rentals. Healthcare, illegal immigration and agricultural land are part of this problem. Environmental issues and natural resources depletion count as a result of human density in the nation.
Ten least densely populated countries in the world
The latest result of population computation, it come out that the following are considered least densely populated countries in the world.
population per sq km
Falkland Islands (UK)
Pitcairn Islands (UK)
French Guiana (France)
We can say that geography isn’t fair. In New York City there are 10,725 people sharing each square kilometer while the world's least-densely populated territory is Greenland, with a rate of 0.03 people per square kilometer.
Top ten languages in the world
Language is perhaps the most important human ability to communicate itself – it allows us to get sustenance as a child, it allows us to get virtually anything we want as an adult. Thus, we use language to express our inner thoughts and emotions, make sense of any complex and abstract ideas, and to learn to communicate with other people. We use language to fulfill our needs and dreams, as well as to establish rules and regulations and more.
Percentage of users as first language
The above list is based on as a first language, all six UN languages: the Arabic, Chinese mandarin, English, Russian and Spanish (Castilian) are considered as mother tongue or as second language of about half of the world’s population and at the same time the official languages in more than half of the world.
There is an estimate of 7,100 languages spoken in different corner of the world. Eighty percent (80%) of these languages are spoken by less than 100,000 people. The almost 300 languages all over the world also have more than a million first speakers. There are about 130 languages are spoken by less than 10 people from a communities that are isolated from each other in the mountains. These often develop multiple languages, just like in Papua New Guinea which has 840 separate languages. In Asia alone there are 2,300 languages are spoken in Asia, 2,140, in Africa, 1,310 in the Pacific, 1,060 in the Americas, and 290 in Europe.
Religions are shared collection of ideas and beliefs that have been passed on from generations of believers or converts. These beliefs are documented doctrines or established cultural practices. In this world people are group according to religion.
Age structure of a population is the distribution of people among various ages and it is represented by a pyramid. This bracket of ages for both men and women is very important to social scientists, public health and health care experts, policy analysts, and policy-makers; because it illustrates population trends like rates of births and deaths. The pyramid of age is also important because the data helps to predict the population growth in the future.
65 years and over
Dependency ratio is the quotient of number of dependent over the total number of population aged 15 to 64 times 100. Ages 15 to 64 here are the working group, where in 0-14 years old and 65 and above years are the non working group. A high ratio means those of working age, and the overall economy, face a greater burden in supporting the aging population.
Median age is the age that divides a population into two numerically equal groups, half the people are younger than this age and half are older. It is a single index that summarizes the age distribution of a population.
male: 29.4 years
female: 30.9 years
total: 30.1 years
Currently, the median age ranges from a low of about 15.7 in Uganda and Gaza Strip to 40 or more in several European countries and Japan.
Population Growth Rate
Population in the world is currently at 7.5 billion as of 2017 and growing at a rate of around 1.11% per year. Population is expected to keep growing and estimates at 8.4 billion by 2030 and 9.6 billion by mid-2050. Annual population growth rate reached its peak in the late 1960s, when it was at 2% and above. Many nations with rapid population growth have low standards of living, whereas many nations with low rates of population growth have high standards of living
The rate result is based on about 148 net additions to the worldwide population every minute or 2.5 every second.
World Birth Rate
Birth rate is the total number of live births per 1,000 of a population in a year, it can be calculated through live births from a universal registration system for births, deaths, and marriages; population counts from a census, and estimation through specialized demographic techniques. Birth rate today reaches 18.5 births/1,000 populations. This rate result is about 258 worldwide births per minute or 4.3 births every second.
Recently, rates of older women getting pregnant are higher than young ones.
World Death Rates
Date rate is the ratio of deaths to the population of a particular area during a particular period of time, usually calculated as the number of deaths per one thousand people per year which is also called the crude rate. Data shows that there are 7.8 death/1000 populations. This rate results in about 108 worldwide deaths per minute or 1.8 deaths every second.
Aside from war, and poverty and famine, diseases is the main cause of death like heart disease, cancer, chronic respiratory diseases, stroke and accidents tops the list.
When people choose to live in the city rather than in the rural areas that is called urbanization, they shift from rural to urban. The regular increase in the proportion of people living in urban areas has increase most likely because of employment and easy access to education. In 2015 people moved and lived in the urban has reached 54% total population. That is 2.05% urbanization rates. It is predicted that by 2050 about 64% of the developing world and 86% of the developed world will be urbanized which equivalent to 3 billion people is living in the cities by 2050 especially in Africa and Asia.

In most sex reproductive species, ratios tend to be 1:1. But human sex ratio is particularly the study of interest of expert. The human sex ratio is the number of males for each 100 female in a population. Sex ratio above 100 means there are more males than females. Sex ratio below 100 means there are more females than males. Sex ratio of 100 means there are equal numbers of females and males. Sexes at birth are affected by considerable factors such as age of mother at birth, sex selective abortion, infanticide and others.
As of 2014, the global sex ratio at birth is estimated at 107 boys to 100 girls which means 1000 boys per 934 girls.
65 years and over
Maternal mortality ratio (per 100 000 live births)
Maternal death is the death of a woman while pregnant or within 42 days of termination of pregnancy, whatever may the cause of her death with the exception of accidental or incidental cause. The cause of the death should be pregnancy related or aggravated by the pregnancy or its management.
Maternal Mortality ratio often referred to as MMR, it is the annual number of female deaths per 100,000 live births from any cause related to or aggravated by pregnancy. In 2015 records shows that maternal mortality is 216 deaths per 100,000 live births. This translates to an average of 2.3 percent reduction compared in the 1990s with a record of 385 deaths per 100,000 live births.
Infant Mortality Rate
Infant mortality rate or IMR is the number of deaths of infants under one year old per 1,000 live births. The rate for a given region is the number of infant dying under one year of age divided by the number of live births during the year, multiplied by 1,000.This rate is often used as an indicator of the level of health in a country.
Total infant mortality
49.4 deaths /1000 live birth
36.1 deaths/1,000 live births
32.1 deaths/1,000 live births
Life Expectancy at Birth
Life expectancy at birth is defined as how long, on average, a newborn can expect to live, if it would not be altered by death. If rates are falling, actual life spans will be higher than life expectancy calculated using current death rates. Gains in life expectancy at birth can be attributed to a number of factors, including rising living standards, improved lifestyle and better education, as well as greater access to quality health services.
Life expectancy is calculated using a statistical tool called a life table. The table is generated from current age- and sex-specific death rates in a given population of one country. Calculating a person’s life expectancy is based on death patterns in the population, and assumes that current death rates will persist throughout that person’s life.
Average total population
Total Fertility Rate
Fertility rate is the number of children who could be born per women or per 1,000 women if she were to pass through the childbearing years of her life or over her lifetime. Total Fertility Rate (TFR) is a synthetic rate, not based on the fertility of any real group of women since this would involve waiting until they had completed childbearing. Total fertility rate of the world is 2.42 children born for every woman. She was to experience the exact current age-specific fertility rates through her lifetime. She was to survive from birth through the end of her reproductive life.
Drinking Water Source
Potable water is very important to all living things especially to human being. People use surface and ground water every day for a variety of purposes, including drinking, cooking, and basic hygiene, in addition to recreational, agricultural, and industrial activities. Thus water must be safe from any particles that affect one’s health.
Majority of public water system which is used by people in the world are supplied by ground water with about 91% share. On the other hand more people of about 68% are supplied by surface water. Surface water comes from wide body of water like river and lakes. This is because large, well-populated metropolitan areas tend to rely on surface water supplies, whereas small, rural areas tend to rely on ground water. Ground water, which is obtained by drilling wells, is water located below the ground surface in pores and spaces in the rock, and is used by approximately 78% of community water systems in the United States and other countries.
From the ground or surface source, water would then be classified into two sources going to the community; the improved water source refers to the nature of its construction or through active intervention, is likely to be protected from outside contamination, in particular from contamination with fecal matter.
Piped water into dwelling
Piped water into yard/plot
Protected dug wells
Protected springs (normally part of a spring supply)
Percentage of population using improved water source
96.5% of population
84.7% of population
91.1% of population
The unimproved source
World Health organization’s effort to improve the source of water of every household has gone a a tremendous achievement, and yet there are still more than 663 million people still relies on unimproved water sources ; surface water from lakes, rivers, dams, or unprotected dug wells or springs for their drinking, cooking, and personal hygiene. Unprotected water source includes cart with small tank or drum, tanker truck and even bottled water.
Percentage of unimproved users:
3.5% of population
15.3% of population
8.9% of population
Sanitation Facility Access
Generally, sanitation refers to the provision of facilities and services for the safe disposal of human urine and feces. Inadequate sanitation is a major cause of disease world-wide and improving sanitation is known to have a significant beneficial impact on health both in households and across communities. It also refers to the maintenance of one’s hygiene through services as garbage segregation and collection and wastewater disposal.
Improved sanitation facility
An improved sanitation facility is defined as one that hygienically separates human excreta from human contact. It is not necessarily identical with sustainable sanitation. The following types of toilets are considered improved.
Connection to a piped sewer system
Connection to a septic system
Flush / pour-flush to a pit latrine
Pit latrine with slab
Ventilated improved pit latrine (abbreviated as VIP latrine)
Percentage of population using improved sanitation
82.3% of population
50.5% of population
67.7% of population
Its sad to know that there’s still 13% of world population or about 946 million people remain with no access to toilets, latrines or any form of sanitation facility, and therefore practice open defecation, resulting in high levels of environmental contamination and exposure to the risks of microbial infections, diarrhea diseases (including cholera), trachoma, and hepatitis. 849 million of them live in rural areas.
Public or shared latrine (meaning a toilet that is used by more than one household)
Flush/pour flush to elsewhere (not into a pit, septic tank, or sewer)
Pit latrine without slab
Hanging toilet / latrine
No facilities / bush / field (open defecation)
Percentage of population who use unimproved sanitation
17.7% of population
49.5% of population
13.3% of population
HIV/AIDS Adult Prevalent Rate
This is estimate of the percentage of adults aged from 15 to 49 years living with HIV/AIDS. The adult prevalence rate is calculated by dividing the estimated number of adults living with HIV/AIDS at yearend by the total adult population at yearend. HIV/AIDs adult prevalent rate as of 2015 is about 0.8% or equivalent to 39.3 million people worldwide.
People Living with HIV/AIDS
Since the start of the AIDS epidemic, more than 78 million people have been infected with HIV and 39 million have died. Good news is that acquiring HIV no longer means certain death. High earner people with AIDS can afford an HIV treatment and can live as nearly the same with life expectancy as a normal person. The sad part is that among people who do have access, great inequities exist. People living with HIV are being left behind because they are not benefitting from health care, employment, education or social protection. This is often due to stigma, discrimination, prohibitive laws and policies or a lack of services.
As of 2016, there are there were approximately 36.7 million people worldwide living with HIV/AIDS, 1.8 million were children, most of these children live in sub-Saharan Africa and were infected by their HIV-positive mothers during pregnancy, childbirth or breastfeeding.
Despite advances in our scientific understanding of HIV and its prevention and treatment as well as years of significant effort by the global health community and leading government and civil society organizations, most people living with HIV or at risk for HIV do not have access to prevention, care, and treatment, and there is still no cure. The vast majority of people living with HIV are in low- and middle-income countries. Sub-Saharan Africa is the most affected region, with an estimated 25.6 million people living with HIV in 2015.
Today, an estimated 35 million people have died from AIDS-related illnesses since the start of the epidemic, including 1.1 million in 2015 worldwide.
Literacy is the ability to read, write, and use arithmetic which include the ability to use language, numbers, images, computers, and other basic means to understand, communicate, gain useful knowledge and use the dominant symbol systems of a culture.
In this modern time, the concept of literacy is expanding in countries to include skills to access knowledge through technology and ability to assess complex contexts. A person who travels and resides in a foreign country but is unable to read or write in the language of the host country would also be regarded by the locals as being illiterate.
Study shows that more than three-quarters of the world's 758 million illiterate adults are found in South Asia and sub-Saharan Africa; of all the illiterate adults in the world, almost two-thirds are women (2014).
School life expectancy (primary to tertiary education)
School life expectancy (SLE) is the total number of years of schooling (primary to tertiary) that a child can expect to receive, assuming that the probability of his or her being enrolled in school at any particular future age is equal to the current enrollment ratio at that age. Average school life expectancy (years), primary to tertiary education: 12.24 years
Facts show that countries in the third world countries have a low school life expectancy.
