India has a population of more than **1.4 billion**, making it one of the largest population centers in human history and widely reported as the world’s most populous country. The population is unevenly distributed, with especially high densities in the Indo-Gangetic plain, major metropolitan regions, and fertile agricultural zones.
## Demographic profile - **Age structure:** India has a relatively young population compared with many high-income countries, though the age profile varies by state. - **Urbanization:** A substantial share of the population still lives in rural areas, but urban growth is rapid. - **Gender:** National sex ratios have historically been imbalanced in some regions, though patterns have evolved over time. - **Migration:** Internal migration is significant, especially from rural areas to cities and between states for work, education, and marriage.
## Ethnic, linguistic, and religious diversity India does not organize population identity primarily around a single ethnic category; instead, language, caste, tribe, region, and religion are often more socially salient.
- **Languages:** Hundreds of languages and many scripts are used. Hindi is widely spoken, English is important in administration, higher education, law, and business, and major regional languages include Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, Kannada, Malayalam, Odia, Punjabi, Assamese, and others. - **Religions:** India has a Hindu majority and large Muslim population, as well as significant communities of Christians, Sikhs, Buddhists, Jains, and others. - **Indigenous communities:** Many **Scheduled Tribes** maintain distinct cultural and linguistic traditions across central, northeastern, and island regions.
## Education, income, and work - Literacy and educational attainment have improved significantly since independence, though outcomes vary by region, gender, and income. - India has a vast labor force spanning agriculture, manufacturing, services, construction, informal work, and a growing technology sector. - Income levels differ sharply between states, cities, and rural districts. - Poverty reduction has occurred over time, but inequality and access gaps remain major policy issues.
For precise counts by age, religion, language, and other categories, official census releases are the main reference point; some indicators await updated nationwide census publication.
