## Demographics
India is one of the world's most populous countries and one of its most diverse in language, religion, ethnicity, caste, and regional identity. National demographic patterns are best understood as a mosaic rather than a single profile.
### Overview - Population: over **1.4 billion** in recent international estimates. - Federal structure: **28 states** and **8 union territories**. - Settlement pattern: large urban agglomerations coexist with a still very substantial rural population. - Diversity: hundreds of languages and thousands of social communities are represented.
### Demographic table | Category | Broad national picture | |---|---| | Population | Over 1.4 billion | | Urban/Rural | Large rural population, with rapid urbanization | | Major religions | Hinduism, Islam, Christianity, Sikhism, Buddhism, Jainism, others | | Official language at Union level | Hindi in Devanagari script and English for official purposes | | Scheduled languages | 22 recognized in the Constitution | | Large language families | Indo-Aryan, Dravidian, Tibeto-Burman, Austroasiatic | | Median age | Relatively young population compared with many major economies |
### Religion (2011 Census, broad picture) | Religion | Approximate share | |---|---| | Hindu | About 80% | | Muslim | About 14% | | Christian | About 2% | | Sikh | About 2% | | Buddhist | Less than 1% | | Jain | Less than 1% | | Other religions and not stated | Small share |
### Language distribution - **Hindi** is widely spoken in many northern and central states, but not as a native language for all Indians. - Major languages include **Bengali, Marathi, Telugu, Tamil, Gujarati, Urdu, Kannada, Odia, Malayalam, Punjabi, Assamese**, and many others. - English has a major role in higher education, administration, law, media, and business.
### Age and household patterns - India has a comparatively young population, though aging is beginning in some states. - Household size and family structure vary by region, class, and urbanization level. - Internal migration for work, education, and marriage is a major demographic force.
### Ethnic and social composition - India does not usually describe its entire population through one simple ethnic breakdown. - Social identity is often discussed through **region, language, caste, tribe, religion, and community**. - Official policy categories include **Scheduled Castes**, **Scheduled Tribes**, and **Other Backward Classes** in many administrative contexts.
### Caution on interpretation - Census, survey, and administrative categories can differ. - Several major indicators await fresh national census updates beyond 2011 baseline structures.
