Colonial Demography of India

Population of Colonial India — Overview

India's population history under British rule is characterised by a prolonged period of stagnation (roughly 1872–1921), caused by extraordinary mortality from famines, epidemics, and poverty, followed by accelerating growth from the 1920s as mortality began to decline.

Census History of British India

The colonial government began systematic population counting as a fiscal and administrative necessity — to assess revenue potential, plan railways, and manage the army.

The census was also used to collect data on religious communities — Hindu, Muslim, Sikh, Christian, and others — which fed into the communal politics of the late colonial period. Lord Curzon's partition of Bengal (1905) was partly justified on demographic grounds (the administrative inconvenience of a large province), but the demographic data was used to frame it in communal terms.

Demographic Stagnation 1872–1921

Between 1872 and 1921 — roughly 50 years — India's population grew by approximately 100 million (from ~200 to ~306 million), averaging barely 0.4% per year. This is extraordinarily slow by any standard. Contemporary Britain was growing at 1.2% per year; other developing regions were growing faster.

The causes were exceptional mortality:

Famine deaths: An estimated 12–29 million deaths in major famines between 1875 and 1900 alone (various estimates; the range reflects methodological differences). These are not disputed as events — only in their precise magnitude.

Epidemic plague: Bubonic plague arrived in Bombay in 1896 and spread across India, killing over 12 million people by 1920. The colonial government's response — forced segregation, invasive house searches, compulsory hospitalisation — caused enormous popular resistance and was a major trigger for early nationalist mobilisation.

Influenza pandemic 1918: The "Spanish flu" killed 12–17 million Indians — one of the worst tolls of any country. India lost approximately 5% of its population in a single year. The pandemic coincided with Mahatma Gandhi's early mass mobilisation campaigns, forcing him to suspend the Rowlatt Satyagraha in part due to illness.

Famine Mortality and the Colonial Record

The famine mortality figures are central to the nationalist economic critique. Historian Mike Davis, in Late Victorian Holocausts (2001), estimated that between 1876 and 1900, "between 12.2 and 29.3 million Indians perished unnecessarily" in famines. The phrase "unnecessarily" is key — his argument is that these were policy-made deaths, not natural disasters.

The 1901 census, conducted in the aftermath of the devastating 1896–97 and 1899–1900 famines, showed population decline in several districts — an exceptional event in demographic history. The famine decade of 1891–1901 is visible in the census data as near-stagnation.

Epidemic Disease Under Colonial Rule

Beyond famine, epidemic disease was a major demographic force. Three diseases caused exceptional mortality in the colonial period:

Poverty Data — Naoroji's Calculations

Dadabhai Naoroji made the first systematic attempt to calculate Indian per-capita income and poverty levels in Poverty and Un-British Rule in India (1901). His estimates:

R.C. Dutt corroborated with detailed regional data. By the 1900s, there was broad agreement among nationalist economists that per-capita income had fallen over the 19th century — the paradox of a country growing more commercially active becoming poorer per person.

Modern scholarship broadly confirms this picture. Angus Maddison's historical GDP estimates show India's per-capita income essentially flat or declining in real terms from 1820 to 1947, while per-capita income in Britain, France, and the United States grew 3–5 times. The colonial period thus represents not just a relative decline in India's global share, but in many periods an absolute decline in average living standards.

Indentured Labour — The New System of Slavery

After the abolition of slavery in the British Empire in 1833–34, plantation owners in British colonies needed new labour. The solution was the indentured labour system, which recruited Indian workers on multi-year contracts.

An estimated 1.3–1.5 million Indians left as indentured labourers between 1834 and 1917. The conditions were harsh: 5-year contracts, restricted movement (workers could not leave without permission, enforced by criminal penalties under the Inland Emigration Act model), accommodation in "coolie lines" (barracks), and wages at or below subsistence.

Internal Migration Under Colonial Rule

Beyond overseas migration, colonial economic transformation drove significant internal migration. Railway construction (from the 1850s) required large labour pools. Tea gardens in Assam drew workers from tribal and low-caste communities in Bihar, Orissa, and Madras under the coercive Inland Emigration Act 1882. Coal mines in Jharia and Raniganj similarly recruited tribal labour.

Urban growth was modest by global standards — India remained overwhelmingly rural in 1947 (about 85% rural). But the largest colonial cities — Calcutta, Bombay, Madras — drew massive migration from surrounding agricultural regions, creating dense urban poor populations that became central to nationalist politics in the early 20th century.

Bombay's cotton mill labour force — recruited primarily from the Konkan coast and Deccan — became a significant political actor in the 1919–1922 Non-Cooperation period. The working class and the peasantry were both mobilised into nationalist politics for the first time in this era.
