India is the most populous country in the world, with one-sixth of the world's population.[12][13][14][15] Between 1975 and 2010, the population doubled to 1.2billion, reaching the billion mark in 2000. According to the UN's World Population dashboard, in 2023 India's population stood at slightly over 1.428 billion, edging past China's population of 1.425 billion people, as reported by the news agency Bloomberg.[15] In 2015, India's population was predicted to reach 1.7billion by 2050.[16][17] In 2017 its population growth rate was 0.98%, ranking 112th in the world; in contrast, from 1972 to 1983, India's population grew by an annual rate of 2.3%.[18]
In 2023, the median age of an Indian was 29.5 years,[19] compared to 39.8 for China and 49.5 for Japan; and, by 2030; India's dependency ratio will be just over 0.4.[20] However, the number of children in India peaked more than a decade ago and is now falling. The number of children under the age of five peaked in 2007, and since then the number has been falling. The number of Indians under 15 years old peaked slightly later (in 2011) and is now also declining.[21]
The sex ratio was 944 females for 1000 males in 2016, and 940 per 1000 in 2011.[26] This ratio has been showing an upwards trend for the last two decades after a continuous decline in the 20th century.[27]
The following table lists estimates for the population of India (including what are now Pakistan and Bangladesh) from prehistory up until 1820. It includes estimates and growth rates according to five economic historians, along with interpolated estimates and overall aggregate averages derived from their estimates.[28][29]
India's population has changed significantly due to migrations, technological advancements, and societal developments. Below is a table of historical population estimates:
Under the Mughal Empire, India experienced a high economic and demographic upsurge,[38] due to Mughal agrarian reforms that intensified agricultural production.[39] 15% of the population lived in urban centres, higher than the percentage of the population in 19th-century British India[40] and contemporary Europe[40] up until the 19th century.[41] These estimates by Abraham Eraly[40] and Paolo Malanima[41] have been criticised by Tim Dyson, who considers them exaggerations and estimates urbanisation of the Mughal Empire to be less than 9% of the population.[42]
Under the reign of Akbar (reigned 1556–1605) in 1600, the Mughal Empire's urban population was up to 17 million people, larger than the urban population in Europe.[43] By 1700, Mughal India had an urban population of 23 million people, larger than British India's urban population of 22.3 million in 1871.[44]Nizamuddin Ahmad (1551–1621) reported that, under Akbar's reign, Mughal India had 120 large cities and 3,200 townships.[40] A number of cities in India had a population between a quarter-million and half-million people,[40] with larger cities including Agra (in Agra Subah) with up to 800,000 people[45] and Dhaka (in Bengal Subah) with over 1 million people.[46] Mughal India also had a large number of villages, with 455,698 villages by the time of Aurangzeb (reigned 1658–1707).[43]
Studies of India's population since 1881 have focused on such topics as total population, birth and death rates, geographic distribution, literacy, the rural and urban divide, cities of a million, and the three cities with populations over eight million: Delhi, Greater Mumbai (Bombay), and Kolkata (Calcutta).[52]
Mortality rates fell in the period 1920–45, primarily due to biological immunisation. Suggestions that it was the benefits of colonialism are refuted by academic thinking: "There can be no serious, informed belief... that... late colonial era mortality diminished and population grew rapidly because of improvements in income, living standards, nutrition, environmental standards, sanitation or health policies, nor was there a cultural transformation...".[53]

Neonatal and infant demographics
Infant mortality rate trends in India (per 1000 births, under age 1, national average)Male to female sex ratio for India, based on its official census data, from 1941 through 2011. The data suggest the existence of high sex ratios before and after the arrival of ultrasound-based prenatal care and sex screening technologies in India.
The table below represents the infant mortality rate trends in India, based on sex, over the last 15 years. In the urban areas of India, average male infant mortality rates are slightly higher than average female infant mortality rates.[86]
Infant mortality rate trend (deaths per 1000) As per NFHS & UNICEF Data.
India's 2011 census shows a serious decline in the number of girls under the age of seven – activists posit that eight million female fetuses may have been aborted between 2001 and 2011.[92]
Ethnic groups
Ethno-Linguistic groups in India chart (2011)[93][94][95]
The national Census of India does not recognise racial or ethnic groups within India,[96] but recognises many of the tribal groups as Scheduled Castes and Tribes (see list of Scheduled Tribes in India). For a list of ethnic groups in the Republic of India (as well as neighbouring countries), see South Asian ethnic groups. According to a 2009 study published by Reich et al.., the modern Indian population is composed of two genetically divergent and heterogeneous populations which mixed in ancient times (about 1,200–3,500 BP), known as Ancestral North Indians (ANI) and Ancestral South Indians (ASI). ASI corresponds to the Dravidian-speaking population of southern India, whereas ANI corresponds to the Indo-Aryan-speaking population of northern India.[97][98] 700,000 people from the United States of any race live in India.[99] Around 150,000 Anglo-Indian people still live in India.[100][101] India is a country with a vast diversity of ethnic groups, each with its own distinct culture, language, and traditions. The major ethnic groups in India include the Indo-Aryans, Dravidians, Sino-Tibetans, Austroasiatic peoples, and various indigenous tribes. These groups are spread across different regions of India, each contributing to the country's rich cultural mosaic.
Population size and structure
Map showing the population density in India, per 2011 Census.
India occupies 2.41% of the world's land area but supports over 18% of the world's population. At the 2001 census 72.2% of the population[103] lived in about 638,000 villages[104] and the remaining 27.8%[103] lived in more than 5,100 towns and over 380 urban agglomerations.[105] By 2011, the share of the population living in rural areas decreased to 68.84%, while that of those living in urban areas increased to 31.16%.[106] India's population exceeded that of the entire continent of Africa by 200 million people in 2010.[107] However, because Africa's population growth is extremely high compared to the rest of the world,[108][109] it is expected to surpass both China and India by the early 2030s.[110]Comparative demographics

India has chosen not to officially count caste population since then.
The following data are from the Mandal report:[citation needed]

Numerous genomic studies have been conducted in the last 15 years to seek insights into India's demographic and cultural diversity. These studies paint a complex and conflicting picture.
In a 2003 study, Basu, Majumder et al.. have concluded on the basis of results obtained from mtDNA, Y-chromosome and autosomal markers that "(1) there is an underlying unity of female lineages in India, indicating that the initial number of female settlers may have been small; (2) the tribal and the caste populations are highly differentiated; (3) the Austroasiatic tribals are the earliest settlers in India, providing support to one anthropological hypothesis while refuting some others; (4) a major wave of humans entered India through the northeast; (5) the Tibeto-Burman tribals share considerable genetic commonalities with the Austroasiatic tribals, supporting the hypothesis that they may have shared a common habitat in southern China, but the two groups of tribals can be differentiated on the basis of Y-chromosomal haplotypes; (6) the Dravidian speaking populations were possibly widespread throughout India but are regulated to South India now; (7) formation of populations by fission that resulted in founder and drift effects have left their imprints on the genetic structures of contemporary populations; (8) the upper castes show closer genetic affinities with Central Asian populations, although those of southern India are more distant than those of northern India; (9) historical gene flow into India has contributed to a considerable obliteration of genetic histories of contemporary populations so that there is at present no clear congruence of genetic and geographical or sociocultural affinities."[135]
In a later 2010 review article, Majumder affirms some of these conclusions, introduces and revises some other. The ongoing studies, concludes Majumder, suggest India has served as the major early corridor for geographical dispersal of modern humans from out-of-Africa. The archaeological and genetic traces of the earliest settlers in India has not provided any conclusive evidence. The tribal populations of India are older than the non-tribal populations. The autosomal differentiation and genetic diversity within India's caste populations at 0.04 is significantly lower than 0.14 for continental populations and 0.09 for 31 world population sets studied by Watkins et al.., suggesting that while tribal populations were differentiated, the differentiation effects within India's caste population was less than previously thought. Majumder also concludes that recent studies suggest India has been a major contributor to the gene pool of southeast Asia.[136][137]
Another study covering a large sample of Indian populations allowed Watkins et al.. to examine eight Indian caste groups and four endogamous south Indian tribal populations. The Indian castes data show low between-group differences, while the tribal Indian groups show relatively high between-group differentiation. This suggests that people between Indian castes were not reproductively isolated, while Indian tribal populations experienced reproductive isolation and drift. Furthermore, the genetic fixation index data show historical genetic differentiation and segregation between Indian castes population is much smaller than those found in east Asia, Africa and other continental populations; while being similar to the genetic differentiation and segregation observed in European populations.[137]
In 2006, Sahoo et al.. reported their analysis of genomic data on 936 Y-chromosomes representing 32 tribal and 45 caste groups from different regions of India. These scientists find that the haplogroup frequency distribution across the country, between different caste groups, was found to be predominantly driven by geographical, rather than cultural determinants. They conclude there is clear evidence for both large-scale immigration into ancient India of Sino-Tibetan speakers and language change of former Austroasiatic speakers, in the northeast Indian region.[138][139]
The genome studies conducted up until 2010 have been on relatively small population sets. Many are from just one southeastern state of Andhra Pradesh (including Telangana, which was part of the state until June 2014). Thus, any conclusions on demographic history of India must be interpreted with caution. A larger national genome study with demographic growth and sex ratio balances may offer further insights on the extent of genetic differentiation and segregation in India over the millenniums.[136]
