Demographics of the world
Demographics of the world include population density, ethnicity, education level, health measures, economic status, religious affiliations and other aspects of the population.
The overall total population of the world is approximately 7.45 billion, to July 2016.
Its overall population density is 50 people per km² (129.28 per sq. mile), excluding Antarctica. Nearly two-thirds of the population lives in Asia and is predominantly urban and suburban, with more than 2.5 billion in the countries of China and India combined. The World's fairly low literacy rate (83.7%) is attributable to impoverished regions. Extremely low literacy rates are concentrated in three regions, the Arab states, South and West Asia, and Sub-Saharan Africa. Christianity, Islam, Hinduism and Buddhism are the four largest religions encompassing a little over 75% of the populace.
The world's largest ethnic group is Han Chinese. Although English (5.52%) is spoken by many as a second language, Mandarin Chinese (14.1%) and Spanish (5.85%) are the languages with the highest number of native speakers.
Human migration has been shifting toward cities and urban centers, with the urban population jumping from 29% in 1950, to 50.5% in 2005.[1] Working backwards from the United Nations prediction that the world will be 51.3 percent urban by 2010, Dr. Ron Wimberley, Dr. Libby Morris and Dr. Gregory Fulkerson estimated May 23, 2007 to be the first time the urban population outnumbered the rural population in history.[2] China and India are the most populous countries,[3] as the birth rate has consistently dropped in developed countries and until recently remained high in developing countries. Tokyo is the largest urban conglomeration in the world.[1][4]
The total fertility rate of the World is estimated as 2.52 children per woman, which is above the replacement fertility rate of approximately 2.1. However, world population growth is unevenly distributed, going from .91 in Macau, to 7.68 in Niger. The United Nations estimated an annual population increase of 1.14% for the year of 2000.[5]
There are approximately 3.38 billion females in the World. The number of males is about 3.41 billion. People under 14 years of age made up over a quarter of the world population (26.3%), and people age 65 and over made up less than one-tenth (7.9%) in 2011.[1]
The world population growth is approximately 1.09%[1]
The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999.[6][7][8]
It reached the 2 billion mark in 1927, the 3 billion mark in 1960, 4 billion in 1974, and 5 billion in 1987.[9] Currently, population growth is fastest among low wealth, Third World countries.[10]
The UN projects a world population of 9.15 billion in 2050, which is a 32.69% increase from 2010 (6.89 billion).[6]

History
Historical migration of human populations begins with the movement of Homo erectus out of Africa across Eurasia about a million years ago. Homo sapiens appear to have occupied all of Africa about 150,000 years ago, moved out of Africa 50,000 - 60,000 years ago, and had spread across Australia, Asia and Europe by 30,000 years BC. Migration to the Americas took place 20,000 to 15,000 years ago, and by 2,000 years ago, most of the Pacific Islands were colonized.
Until c. 10,000 years ago, humans lived as hunter-gatherers. They generally lived in small nomadic groups known as band societies. The advent of agriculture prompted the Neolithic Revolution, when access to food surplus led to the formation of permanent human settlements. About 6,000 years ago, the first proto-states developed in Mesopotamia, Egypt's Nile Valley and the Indus Valley. Early human settlements were dependent on proximity to water and, depending on the lifestyle, other natural resources used for subsistence. But humans have a great capacity for altering their habitats by means of technology.
Since 1800, the human population has increased from one billion[13] to over seven billion,[14] In 2004, some 2.5 billion out of 6.3 billion people (39.7%) lived in urban areas. In February 2008, the U.N. estimated that half the world's population would live in urban areas by the end of the year.[15] Problems for humans living in cities include various forms of pollution and crime,[16] especially in inner city and suburban slums. Both overall population numbers and the proportion residing in cities are expected to increase significantly in the coming decades.[17]
Cities
The World has hundreds of major cities spread across 6 continents. Most are in coastal regions.
As of 2005, the World had 62 metropolitan areas with a population of over 3,000,000 people each.[18]
As of 2010, about 3 billion people live in or around urban areas.[1]
The following table shows the populations of the top ten conglomerations.

Population density
![](../I/m/Countries_by_Population_Density_in_2015.svg.png)
The world's population is 7 billion[27] and Earth's total area (including land and water) is 510 million square kilometers (197 million square miles).[28] Therefore, the worldwide human population density is 7 billion ÷ 510 million = 13.7 per km² (35.5 per sq. mile). If only the Earth's land area of 150 million km² (58 million sq. miles) is taken into account, then human population density increases to 46.7 per km² (117.2 per sq. mile). This calculation includes all continental and island land area, including Antarctica. If Antarctica is also excluded, then population density rises to 50 people per km² (129.28 per sq. mile).[29] Considering that over half of the Earth's land mass consists of areas inhospitable to human inhabitation, such as deserts and high mountains, and that population tends to cluster around seaports and fresh water sources, this number by itself does not give any meaningful measurement of human population density.
Several of the most densely populated territories in the world are city-states, microstates or dependencies.[30][31] These territories share a relatively small area and a high urbanization level, with an economically specialized city population drawing also on rural resources outside the area, illustrating the difference between high population density and overpopulation.

Religion
![](../I/m/Prevailing_world_religions_map.png)
The table below lists religions classified by philosophy; however, religious philosophy is not always the determining factor in local practice. Please note that this table includes heterodox movements as adherents to their larger philosophical category, although this may be disputed by others within that category. For example, Cao Đài is listed because it claims to be a separate category from Buddhism, while Hòa Hảo is not, even though they are similar new religious movements.
The population numbers below are computed by a combination of census reports, random surveys (in countries where religion data is not collected in census, for example United States or France), and self-reported attendance numbers, but results can vary widely depending on the way questions are phrased, the definitions of religion used and the bias of the agencies or organizations conducting the survey. Informal or unorganized religions are especially difficult to count. Some organizations may wildly inflate their numbers.

Since the late 19th century, the demographics of religion have changed a great deal. Some countries with a historically large Christian population have experienced a significant decline in the numbers of professed active Christians: see demographics of atheism. Symptoms of the decline in active participation in Christian religious life include declining recruitment for the priesthood and monastic life, as well as diminishing attendance at church. On the other hand, since the 19th century, large areas of sub-Saharan Africa have been converted to Christianity, and this area of the world has the highest population growth rate. In the realm of Western civilization, there has been an increase in the number of people who identify themselves as secular humanists. In many countries, such as the People's Republic of China, communist governments have discouraged religion, making it difficult to count the actual number of believers. However, after the collapse of communism in numerous countries of Eastern Europe and the former Soviet Union, religious life has been experiencing resurgence there, both in the form of traditional Eastern Christianity and in the forms of Neopaganism and Far Eastern religions.
Following is some available data based on the work of the World Christian Encyclopedia:[58]

Studies conducted by the Pew Research Center have found that, generally, poorer nations had a larger proportion of citizens who found religion to be very important than richer nations, with the exceptions of the United States[63] and Kuwait.[64]
Marriage
The average age of marriage varies greatly from country to country, and has varied through time. Women tend to marry at the same age as men and currently varies from 17.6 for women in Niger, to 32.4 for women in Denmark while men range from 22.6 in Mozambique to 35.1 in Sweden.[65]

Demographic statistics
The following demographic statistics are from the CIA World Factbook, unless otherwise indicated.[68]
Age structure
![](../I/m/Median_age.png)
According to the 2006 CIA World Factbook, around 27% of the world's population is below 15 years of age.[69]
- 0–14 years: 26.3% (male 944,987,919/female 884,268,378)[1]
- 15–64 years: 65.9% (male 2,234,860,865/female 2,187,838,153)[1]
- 65 years and over: 7.9% (male 227,164,176/female 289,048,221) (2011 est.)[1]
- Median Age - 28.4 years (male: 27.7 years, female: 29 years, 2009 est.)
According to a report by the Global Social Change Research Project, worldwide, the percent of the population age 0-14 declined from 34% in 1950 to 27% in 2010. On the other hand, the percent elderly (60+) increased during the same period from 8% to 11%.[70]
Population growth rate
![](../I/m/World_population_growth_rate_1950%E2%80%932050.svg.png)
The sharp decline in world population growth in the early 1960s caused primarily by the Great Chinese Famine
Globally, the growth rate of the human population has been declining since peaking in 1962 and 1963 at 2.20% per annum. In 2009, the estimated annual growth rate was 1.1%.[71] The CIA World Factbook gives the world annual birthrate, mortality rate, and growth rate as 1.915%, 0.812%, and 1.092% respectively[72] The last one hundred years have seen a rapid increase in population due to medical advances and massive increase in agricultural productivity[73] made possible by the Green Revolution.[74][75][76]
The actual annual growth in the number of humans fell from its peak of 88.0 million in 1989, to a low of 73.9 million in 2003, after which it rose again to 75.2 million in 2006. Since then, annual growth has declined. In 2009, the human population increased by 74.6 million, which is projected to fall steadily to about 41 million per annum in 2050, at which time the population will have increased to about 9.2 billion.[71] Each region of the globe has seen great reductions in growth rate in recent decades, though growth rates remain above 2% in some countries of the Middle East and Sub-Saharan Africa, and also in South Asia, Southeast Asia, and Latin America.[77]
Some countries experience negative population growth, especially in Eastern Europe mainly due to low fertility rates, high death rates and emigration. In Southern Africa, growth is slowing due to the high number of HIV-related deaths. Some Western Europe countries might also encounter negative population growth.[78] Japan's population began decreasing in 2005.[79]
Population in the world increased from 1990 to 2008 with 1,423 million and 27% growth. Measured by persons, the increase was highest in India (290 million) and China (192 million). Population growth was highest in Qatar (174%) and United Arab Emirates (140%).[80]

According to the CIA - The World Factbook, the country with the highest birth rate currently is Niger at 51.26 births per 1000 people. The country with the lowest birth rate is Japan at 7.64 births per 1000 people. Hong Kong, a Special Administrative Region of China, is at 7.42 births per 1000 people. As compared to the 1950s, birth rate was at 36 births per 1000 in the 1950s,[82] birth rate has declined by 16 births per 1000 people. In July, 2011, the U.S. National Institutes of Health announced that the adolescent birth rate continues to decline.[83] Birth rates vary even within the same geographic areas. In Europe, as of July 2011, Ireland's birth rate is 16.5 per cent, which is 3.5 per cent higher than the next-ranked country, the UK. France has a birth rate of 12.8 per cent while Sweden is at 12.3 per cent.[84] In July, 2011, the UK's Office for National Statistics (ONS) announced a 2.4% increase in live births in the UK in 2010 alone.[85] This is the highest birth rate in the UK in 40 years.[85] By contrast, the birth rate in Germany is only 8.3 per 1,000, which is so low that both the UK and France, which have significantly smaller populations, produced more births in the last year.[86] Birth rates also vary within the same geographic area, based on different demographic groups. For example, in April 2011, the U.S. CDC announced that the birth rate for women over the age of 40 in the U.S. rose between 2007 and 2009, while it fell among every other age group during the same time span.[87] In August 2011, Taiwan's government announced that its birth rate declined in the previous year, despite the fact that it implemented a host of approaches to encourage its citizens to have babies.[88]
Birth rates ranging from 10-20 births per 1000 are considered low, while rates from 40-50 births per 1000 are considered high. There are problems associated with both an extremely high birth rate and an extremely low birth rate. High birth rates can cause stress on the government welfare and family programs to support a youthful population. Additional problems faced by a country with a high birth rate include educating a growing number of children, creating jobs for these children when they enter the workforce, and dealing with the environmental effects that a large population can produce. Low birth rates can put stress on the government to provide adequate senior welfare systems and also the stress on families to support the elders themselves. There will be less children or working age population to support the constantly growing aging population.

According to the World Health Organization, the 10 leading causes of death in 2002 were:
- 12.6% Ischaemic heart disease
- 9.7% Cerebrovascular disease
- 6.8% Lower respiratory infections
- 4.9% HIV/AIDS
- 4.8% Chronic obstructive pulmonary disease
- 3.2% Diarrhoeal diseases
- 2.7% Tuberculosis
- 2.2% Trachea/bronchus/lung cancers
- 2.2% Malaria
- 2.1% Road traffic accidents
Causes of death vary greatly between first and third world countries.
According to Jean Ziegler (the United Nations Special Rapporteur on the Right to Food for 2000 to March 2008), mortality due to malnutrition accounted for 58% of the total mortality in 2006: "In the world, approximately 62 millions people, all causes of death combined, die each year. In 2006, more than 36 millions died of hunger or diseases due to deficiencies in micronutrients".[91]
Of the roughly 150,000 people who die each day across the globe, about two thirds—100,000 per day—die of age-related causes.[92] In industrialized nations, the proportion is much higher, reaching 90%.[92]
Sex ratio

Countries with more males than females.
No data |
The Northern Mariana Islands have the highest female ratio with 0.77 males per female. Qatar has the highest male ratio, with 2.87 males/female. For the group aged below 15, Sierra Leone has the highest female ratio with 0.96 males/female, and the Republic of Georgia and the People's Republic of China are tied for the highest male ratio with 1.13 males/female (according to the 2006 CIA World Factbook).
The value for the entire world population is 1.01 males/female,[93] with 1.07 at birth, 1.06 for those under 15, 1.02 for those between 15 and 64, and 0.78 for those over 65.
The "First World" G7 members all have a sex ratio in the range of 0.95–0.98 for the total population, of 1.05–1.07 at birth, of 1.05–1.06 for the group below 15, of 1.00–1.04 for the group aged 15–64, and of 0.70–0.75 for those over 65.
Countries on the Arabian Peninsula tend to have a 'natural' ratio of about 1.05 at birth but a very high ratio of males for those over 65 (Saudi Arabia 1.13, United Arab Emirates 2.73, Qatar 2.84), indicating either an above-average mortality rate for females or a below-average mortality for males, or, more likely in this case, a large population of aging male guest workers. Conversely, countries of Eastern Europe (the Baltic states, Belarus, Ukraine, Russia) tend to have a 'normal' ratio at birth but a very low ratio of males among those over 65 (Russia 0.46, Latvia 0.48, Ukraine 0.52); similarly, Armenia has a far above average male ratio at birth (1.17), and a below-average male ratio above 65 (0.67). This effect may be caused by emigration and higher male mortality as result of higher Soviet era deaths; it may also be related to the enormous (by western standards) rate of alcoholism in the former Soviet states. Another possible contributory factor is an aging population, with a higher than normal proportion of relatively elderly people: we recall that due to higher differential mortality rates the ratio of males to females reduces for each year of age.

There is an inverse correlation between income and fertility, wherein developed countries usually have a much lower fertility rate. Various fertility factors may be involved, such as education and urbanization. Mortality rates are low, birth control is understood and easily accessible, and costs are often deemed very high because of education, clothing, feeding, and social amenities. With wealth, contraception becomes affordable. However, in countries like Iran where contraception was made artificially affordable before the economy accelerated, birth rate also rapidly declined. Further, longer periods of time spent getting higher education often mean women have children later in life. Female labor participation rate also has substantial negative impact on fertility. However, this effect is neutralized among Nordic or liberalist countries.[95]
In undeveloped countries on the other hand, families desire children for their labour and as caregivers for their parents in old age. Fertility rates are also higher due to the lack of access to contraceptives, generally lower levels of female education, and lower rates of female employment in industry.
Unemployment rate
8.7% (2010 est.) 8.2% (2009 est.) note: 30% combined unemployment and underemployment in many non-industrialized countries; developed countries typically 4%-12% unemployment (2007 est.)

Worldwide, English is used widely as a lingua franca and can be seen to be the dominant language at this time. The world's largest language by native Speakers is Mandarin Chinese which is a first language of around 960 million people, or 12.44% of the population, predominantly in the Greater China. Spanish is spoken by around 330 to 400 million people, predominantly in the Americas and Spain. Arabic is spoken by around 280 million people. Hindi is spoken by about 200 million speakers, mostly in India. Bengali is spoken by around 230 million people, predominantly in India and Bangladesh. Portuguese is spoken by about 230 million speakers in Portugal, Brazil, East Timor, and Southern Africa.
There are numerous other languages, grouped into nine major families:
- Indo-European languages 46% (Europe, Western Asia, South Asia, North Asia, North America, South America, and Oceania)
- Sino-Tibetan languages 21% (East Asia)
- Niger–Congo languages 6.4% (Sub-Saharan Africa)

- Austronesian languages 5.9% (Oceania, Madagascar, and Maritime Southeast Asia)
- Dravidian languages 3.7% (South Asia)
- Altaic languages (controversial combination of Turkic, Mongolic, and Tungusic families) 2.3% (Central Asia, North Asia (Siberia), and Anatolia)[96]
- Austroasiatic languages 1.7% (Mainland Southeast Asia)
- Tai–Kadai languages 1.3% (Southeast Asia)
There are also hundreds of non-verbal sign languages.
Education
4.4% of GDP spent on Education (2007)
Total population: 83.7% over the age of 15 can read and write, 88.3% male and 79.2% female note: over two-thirds of the world's 793 million illiterate adults are found in only eight countries (Bangladesh, China, Egypt, Ethiopia, India, Indonesia, Nigeria, and Pakistan); of all the illiterate adults in the world, two-thirds are women; extremely low literacy rates are concentrated in three regions, the Arab states, South and West Asia, and Sub-Saharan Africa, where around one-third of the men and half of all women are illiterate (2005-09 est.)
As of 2008, the school life expectancy (primary to tertiary education) for a man or woman is 11 years.

- ↑ Figures for the population of Jains differ from just over six million to twelve million due to difficulties of Jain identity, with Jains in some areas counted as a Hindu sect. Many Jains do not return Jainism as their religion on census forms for various reasons such as certain Jain castes considering themselves both Hindu and Jain. Following a major advertising campaign urging Jains to register as such, the 1981 Census of India returned 3.19 million Jains. This was estimated at the time to still be half the true number. The 2001 Census of India had 8.4 million Jains.
- ↑ Historically, the Bahá'í Faith arose in 19th century Persia, in the context of Shi'a Islam, and thus may be classed on this basis as a divergent strand of Islam, placing it in the Abrahamic tradition. However, the Bahá'í Faith considers itself an independent religious tradition, which draws from Islam but also other traditions. The Bahá'í Faith may also be classed as a new religious movement, due to its comparatively recent origin, or may be considered sufficiently old and established for such classification to not be applicable.
