Odisha’s population was 4,19,74,218 (about 4.2 crore) in the 2011 Census, about 3.47% of India’s population, making it the 11th most populous state. Official projections put it at about 4.72 crore in 2026, around 3.3% of India’s total, growing at under 0.6% a year (StatisticsTimes, citing the National Commission on Population).
Because the 2021 Census was postponed, the 2011 Census remains the latest full count. The next Census, India’s first digital one with caste enumeration, is scheduled for 2027. Newer estimates of fertility, mortality and health come from the Sample Registration System (SRS) and the National Family Health Survey (NFHS-5, 2019–21).
Odisha’s demography is distinctive. It has one of India’s largest tribal populations, a low level of urbanisation, a high sex ratio, fertility now below replacement level, and wide gaps between its coastal and tribal districts. This article covers population growth, distribution and density, sex ratio, age structure and health, literacy, urbanisation, social composition, migration and work, and the main demographic challenges.
Population growth
Odisha’s population has grown steadily for a century, except for a dip in 1911–21, but its growth has been slower than India’s for decades.
Growth was fastest between 1951 and 1991, when falling death rates met high birth rates. Since then it has slowed: the decadal growth rate fell to about 14% in 2001–11, below India’s 17.7%, and annual growth is now projected at under 0.6%. As a result, Odisha’s share of India’s population has fallen from a peak of about 4.5% in 1911 to about 3.3% today, and the state slipped from 9th to 11th most populous.
Distribution and density
Odisha’s population density was 270 persons per sq km in 2011, below India’s 382, but this average hides a sharp contrast between the crowded coast and the thinly peopled hills.
| Region | Density pattern | Examples (2011, persons per sq km) |
|---|---|---|
| Coastal deltas | Very high: fertile alluvium, irrigation, towns and roads | Khordha 800, Cuttack 667, Jagatsinghpur 646, Balasore 638, Jajpur 633 |
| Western plains and central tablelands | Moderate: paddy plains, Hirakud command, industrial towns | Jharsuguda 278, Dhenkanal 268, Subarnapur 261, Bargarh 254 |
| Northern plateau | Moderate to low: forests, mines and industrial pockets | Mayurbhanj 242, Keonjhar 217, Sundargarh 215 |
| Eastern Ghats and tribal south | Low: hills, forests, poor soils, shifting cultivation | Kandhamal 96, Malkangiri 106, Deogarh 112, Boudh 128, Rayagada 137 |
The main factors behind this pattern are:
- Relief and soils: flat, fertile deltas support dense farming populations, while steep, forested hills support few people.
- Water and irrigation: canal-irrigated areas of the deltas and Hirakud command can feed more people per hectare.
- Urban and industrial growth: Bhubaneswar, Cuttack, Rourkela, Sambalpur and Berhampur draw in migrants and raise density.
- History: the coastal plains have been settled for millennia, while many hill areas were remote and sparsely populated by tribal communities.
Ganjam is the most populous district (about 35 lakh people), and Deogarh the least (about 3 lakh).
Sex ratio, age structure and vital rates
Odisha has a favourable overall sex ratio and has brought fertility below replacement level, but infant and maternal mortality are still higher than in the best-performing states.
Sex ratio
- Overall sex ratio (2011): 979 females per 1,000 males, well above India’s 943. It is highest in the tribal southern districts (Rayagada, Gajapati, Kandhamal) and lowest in urbanised and industrial districts such as Khordha and Sundargarh, where male migrants concentrate.
- Child sex ratio (0–6 years, 2011): about 941, above India’s 918 but lower than in earlier censuses.
- Sex ratio at birth has been a concern, falling below 940 in some surveys, which points to the need for continued vigilance against sex selection.
Age structure
In 2011, roughly 29% of Odisha’s population was under 15, about 63% was of working age (15–59), and about 9% was 60 or older. With fertility falling, the share of children is shrinking and the share of older people is rising. Odisha has a demographic dividend window now, but it is ageing faster than many northern states.
Fertility, mortality and life expectancy
| Indicator | Odisha | India | Source period |
|---|---|---|---|
| Total fertility rate (TFR) | 1.9 | 2.2 | NFHS-5 era |
| Crude birth rate (per 1,000) | 18 | 19.7 | SRS |
| Neonatal mortality rate (per 1,000 live births) | 31 | 23 | SRS |
| Under-five mortality rate (per 1,000 live births) | 44 | 36 | SRS |
| Maternal mortality ratio (per 1 lakh live births) | 150 | 113 | SRS |
| Life expectancy at birth (years) | 69.3 | 69.4 | SRS abridged life tables |
Source: NHSRC Health Dossier 2021: Odisha. More recent SRS rounds show further declines in infant and maternal mortality, and NITI Aayog data put Odisha’s life expectancy at about 70.3 years in 2020 (Data Commons).
Odisha’s TFR is now below the replacement level of 2.1, so future growth will come mainly from its young age structure (population momentum) rather than large families. Fertility remains higher in the tribal southern districts than on the coast.
Literacy and education
Odisha’s literacy rate rose to about 72.9% in 2011 (males about 81.6%, females about 64%), close to India’s 74%. Literacy has improved quickly from about 49% in 1991 and 63% in 2001, but large gaps remain.
| Gap | Pattern (Census 2011, approx.) |
|---|---|
| Gender | Male literacy is about 17 percentage points higher than female literacy |
| Region | Coastal districts lead: Khordha about 87%, Jagatsinghpur about 87%, Cuttack and Kendrapara about 85%. Tribal southern districts lag: Nabarangpur about 46%, Malkangiri about 49%, Koraput and Rayagada about 49–50% |
| Social group | Scheduled Tribe literacy was only about 52%, and ST female literacy about 41% |
| Rural–urban | Urban literacy (about 86%) is far higher than rural literacy (about 70%) |
Recent efforts to close these gaps include residential schools for tribal children run by the ST & SC Development Department, the state’s school transformation programmes, scholarships and cycles for girls, mother-tongue-based multilingual education in tribal languages, and the expansion of colleges and universities across districts. Odisha also hosts national institutions such as IIT Bhubaneswar, NIT Rourkela, AIIMS Bhubaneswar, NISER and IIM Sambalpur.
Urbanisation
Odisha is one of India’s least urbanised states: only about 16.7% of its people lived in towns and cities in 2011, about half the national figure of 31.2%. More than four out of five people still live in villages.
Pattern of urbanisation
- The most urbanised districts are Khordha (Bhubaneswar), Jharsuguda and Sundargarh (Rourkela), where industry and services attract migrants.
- The least urbanised are rural districts such as Boudh, Nayagarh, Kendrapara and the southern tribal districts, where most people farm.
- Urban growth is now fastest around Bhubaneswar–Cuttack, the industrial towns of Angul, Jharsuguda and Kalinganagar, and Berhampur.
Major cities
| City | District | Character |
|---|---|---|
| Bhubaneswar | Khordha | State capital; “Temple City”; largest city, IT and education hub; a Smart City |
| Cuttack | Cuttack | Former capital; commercial city; “Silver City” |
| Rourkela | Sundargarh | Steel city built around the SAIL plant |
| Berhampur (Brahmapur) | Ganjam | Largest city of southern Odisha; “Silk City” |
| Sambalpur | Sambalpur | Main city of western Odisha |
| Puri | Puri | Pilgrim and tourist city; became a municipal corporation in 2026 |
| Balasore, Bhadrak, Baripada, Jharsuguda, Angul, Jeypore | Various | Growing district towns and industrial centres |
Odisha’s urban local bodies include municipal corporations (Bhubaneswar, Cuttack, Berhampur, Sambalpur, Rourkela and now Puri), municipalities and Notified Area Councils (NACs). The state’s 2025 decisions created more NACs and upgraded several to municipalities (Wikipedia: urban local bodies in Odisha). The Bhubaneswar–Cuttack–Puri–Paradip Economic Region is being planned as a single growth region.
Social composition
Odisha has one of India’s most diverse populations, with a very large tribal community, a sizeable Scheduled Caste population and a mostly Hindu, Odia-speaking majority.
Scheduled Tribes
About 22.8% of Odisha’s people (roughly 96 lakh in 2011) belong to Scheduled Tribes, one of the highest shares among major states. Odisha has 62 recognised tribal communities, including 13 Particularly Vulnerable Tribal Groups (PVTGs), the most of any state.
- Largest tribes: Khond (Kandha), Gond, Santal, Kolha, Munda, Saora, Shabar, Bhuyan, Bhumij, Oraon and Paraja.
- PVTGs include the Bonda, Dongria Kondh, Juang, Lanjia Saora, Paudi Bhuyan, Didayi, Hill Kharia, Mankirdia, Birhor, Chuktia Bhunjia, Lodha, Kutia Kondh and Saora.
- Tribal-majority districts: Mayurbhanj, Malkangiri, Rayagada, Nabarangpur, Gajapati, Kandhamal, Koraput and Sundargarh have tribal shares of about half or more.
Scheduled Castes
About 17.1% of the population belongs to Scheduled Castes, concentrated in the coastal and western districts such as Subarnapur, Boudh, Jajpur, Kendrapara and Bhadrak.
Religion (Census 2011, approx.)
| Religion | Share of population |
|---|---|
| Hindu | 93.6% |
| Christian | 2.8% |
| Muslim | 2.2% |
| Others (including tribal faiths such as Sarna), Sikh, Buddhist, Jain | About 1.4% |
Christians are concentrated in the tribal districts of Kandhamal, Gajapati, Sundargarh and Rayagada. Muslims live mainly in coastal towns such as Cuttack, Bhadrak, Balasore and Jajpur.
Language
Odia, a classical language of India since 2014, is the mother tongue of about 82–83% of the population and the state’s official language. Other languages include Hindi, Telugu (in the southern border districts), Bengali (in the north), Urdu, and many tribal languages such as Santali (with its own Ol Chiki script and included in the Eighth Schedule), Ho, Kui, Mundari, Sora and Kuvi. Desia is a common link language in the Koraput region.
Work and migration
Work participation
The 2011 Census counted about 1.75 crore workers in Odisha, of whom about 61% were main workers and the rest marginal (seasonal) workers (Wikipedia: Economy of Odisha). Recent labour surveys show strong gains: the Odisha Economic Survey 2025-26 reports overall labour force participation at about 64.5%, and female participation rising sharply to about 48.7%, well above the national average of about 40% (The Orissa Today).
Agriculture and allied activities still employ nearly half the workforce, with the rest in construction, mining and manufacturing, trade and services. Much work is informal, seasonal and low-paid, especially in rural and tribal areas.
Out-migration
Odisha is a major source of migrant workers to other states.
- Western Odisha (Bolangir, Nuapada, Kalahandi, Bargarh): seasonal “dadan” migration of whole families to brick kilns in Andhra Pradesh and Telangana, often through advances from labour agents.
- Ganjam: long-standing migration of men to textile and diamond units in Surat (Gujarat), and to Mumbai.
- Coastal and other districts: construction, factory and service work in Kerala, Tamil Nadu, Karnataka, Gujarat, Maharashtra and Delhi; skilled youth to Bengaluru, Hyderabad, Pune and abroad.
Remittances support many rural households, but distress migration exposes workers to exploitation and bonded labour, and the COVID-19 lockdown of 2020 saw lakhs of migrants return home.
In-migration
Industrial and urban centres such as Rourkela, Bhubaneswar, Cuttack, Angul–Talcher, Jharsuguda, Kalinganagar and Paradip attract workers from within Odisha and from neighbouring states such as Jharkhand, West Bengal, Bihar and Chhattisgarh.
Demographic challenges
- Regional and social inequality. Coastal districts are far ahead of the tribal south and west on literacy, health and income.
- Infant and maternal mortality, though falling, remain above the levels of leading states, especially in remote tribal areas.
- Low urbanisation limits non-farm jobs and services.
- Distress migration from western and southern districts.
- Gender gaps in literacy and a sex ratio at birth that needs watching.
- Ageing: with fertility below replacement, Odisha’s elderly population will grow quickly and need pensions and healthcare.
- Disaster vulnerability: a large coastal population exposed to cyclones and floods.
- Outdated data: with no census since 2011, planning relies on projections until the 2027 Census results arrive.
Way forward
- Focus health, nutrition and education spending on tribal and backward districts to close the gaps.
- Improve maternal and newborn care, and reduce malnutrition and anaemia.
- Use the demographic dividend through skilling and job creation in industry, services and agro-processing.
- Plan urban growth around Bhubaneswar–Cuttack and other regional centres to create jobs closer to home.
- Protect migrant workers and create local livelihoods in migration-prone districts.
- Prepare for an ageing population with pensions, elder care and health insurance.
Conclusion
Odisha’s population of about 4.7 crore is growing slowly, with fertility now below replacement. It has a high sex ratio, a large and diverse tribal population, and only a small urban share. Literacy, health and mortality have improved sharply in recent decades, but the gap between the coastal plains and the tribal hills remains the central demographic challenge. The 2027 Census will give the first full picture of these changes since 2011.
