Human Settlements and Urbanisation in India

1. Human settlements: meaning, site and the rural-urban contrast

Read the detailed note →

• Human settlement: a group of houses of any type or size where people live, plus the land around it that they use to earn a living. Settling means grouping people and dividing up land. Settlements range from a hamlet to a metropolitan city. As size grows, the economy, society, ecology and technology all change.
• Rural settlement: small, widely spaced villages that live on land-based primary work such as farming. People move less, and social ties are close and personal.
• Urban settlement: fewer, larger, compact places that do secondary and tertiary work (making goods and giving services). A city is a node of growth (a centre that drives the economy around it). It sends goods and services to its rural hinterland (the area that depends on it) and gets food and raw materials back, through transport links. Social ties are formal and life is fast. Class 12, Geographical Perspective adds that the rural-urban split is also social, cultural and technological, and that towns are very unequal inside.
• Site of settlement (Class 11, Topographical Maps): the actual ground a settlement stands on. It is chosen for water, food, relief (the shape of the land), work and defence.
• Wet-point sites: next to rivers and springs.
• Dry-point sites: on levees (raised river banks) and other high ground in flood plains.

• Defensive hilltops, and gaps, fords and crossroads for trade.

• Situation is a place's position in relation to the areas and routes around it.

• Census 2011: 6,40,867 villages and 7,935 towns.

2. Types of rural settlement and the factors behind them

Read the detailed note →

• Type depends on how much land is built up and how far apart the houses are. It is shaped by three kinds of factor:
• physical: terrain, altitude, climate, water;
• cultural and ethnic: social structure, caste, religion;
• security: defence against theft and robbery.

Type	Features	Where (Class 12, Human Settlements)
Clustered settlement (agglomerated or nucleated)	Compact houses kept apart from the fields. Streets run in rectangular, radial or linear patterns	Fertile alluvial plains (northern plains) and the north-east. Built close for defence in Bundelkhand and Nagaland, and to share scarce water in Rajasthan
Semi-clustered settlement (fragmented)	A scattered area starts to cluster, or a big village splits. The dominant land-owning group lives in the centre; lower groups and menial workers live on the edges	Gujarat plain, parts of Rajasthan
Hamleted settlement	One village split into separate units that share one name: panna, para, palli, nagla, dhani. Usually caused by social and ethnic factors	Middle and lower Ganga plain, Chhattisgarh, lower Himalayan valleys
Dispersed settlement (isolated)	Lone huts or tiny hamlets in remote jungles or on small hills, with farms or pasture on the slopes. Caused by very broken terrain	Meghalaya, Uttarakhand, Himachal Pradesh, Kerala, Nagaland

• NCERT puts Nagaland under both clustered (for defence) and dispersed (in the hills).
• Linear settlement (Class 11): houses in a line along a river valley, road, embankment, canal or coast, as in Kerala's coastal villages. On toposheets you also see fan-shaped towns at crossroads and radial nodal towns.
• Exercise trap: dispersed settlements are expected in the forests and hills of the north-east, not on the Ganga plain.

3. What counts as urban: the Census definition and units

Read the detailed note →

• Census definition of urban area (Census 2001 and 2011). A place is urban if it is either of these two:
• a statutory town: any place with a municipality, corporation, cantonment board or notified town area committee, whatever its size or jobs;

• a census town: a place with no urban local body that meets all three tests together: at least 5,000 people, at least 75% of male main workers in non-farm work, and a density of at least 400 persons per sq km.

• NCERT quotes Census 1991 and joins the two kinds of town with "and". The Census uses "or". The exercise trap is "75% in the primary sector", which is FALSE.

• Census 2011: 7,935 towns, of which 4,041 were statutory and 3,894 census towns. Census towns jumped from 1,362 in 2001 and explain much of the 2001-11 urban rise. Gram panchayats run them, so they lack urban services and planning. Large villages that fall just below the tests add "hidden urbanisation".
• Urban agglomeration (UA): one continuous urban spread. It is either a town with its outgrowths (such as a railway colony or university campus) or two or more towns that touch. Census 2011 had 475 UAs. NCERT's Table 2.1 counts towns and UAs together: 6,171 in 2011.

4. Evolution of towns in India: ancient, medieval, colonial and post-1947

Read the detailed note →

• Harappa and Mohenjodaro (Indus valley civilisation) show towns from prehistoric times. Towns kept rising and falling until the Europeans came.
• Ancient towns (over 2,000 years old) were mostly religious and cultural centres: Varanasi, Prayag (Prayagraj), Pataliputra (Patna), Madurai.
• Medieval towns: about 100 of today's towns. Most were capitals of kingdoms, often fort towns built on the ruins of ancient towns: Delhi, Hyderabad, Jaipur, Lucknow, Agra, Nagpur.
• Modern towns:
• Europeans first built coastal trading ports: Surat, Daman, Goa, Pondicherry.
• The British then built up three main nodes, Mumbai, Chennai and Kolkata, in British style.
• They added administrative centres, hill stations (Shimla, Darjeeling, Ooty), civil lines and cantonments.
• Industrial towns came after 1850, such as Jamshedpur (TISCO, 1907).

• Railways were laid towards the port cities, which made the coastal ports dominant.

• Post-independence new towns:

• Planned capitals: Chandigarh (Le Corbusier), Bhubaneswar, Gandhinagar, Dispur.
• Industrial towns: Durgapur, Bhilai, Sindri, Barauni.

• Many medium and small towns grew as investment reached rural areas.

• Satellite town: a smaller town that grows around a big city. It depends on the city for jobs and services and takes some of its crowding. Examples are Ghaziabad, Rohtak and Gurugram around Delhi, all in the National Capital Region (NCR Planning Board Act 1985). Navi Mumbai was planned from 1971 as a counter-magnet (a rival centre built to pull growth away) to Mumbai.

5. Urbanisation in India: level, trends and components

Read the detailed note →

• Urbanisation (level): the percentage of a country's people who live in urban areas.
• Table 2.1 (Class 12, Human Settlements):

Year	Urban %	Decadal growth
1901	10.84	—
1951	17.29	41.42%
1981	23.34	46.14% (peak)
2001	27.78	31.13%
2011	31.16 (NCERT, provisional; final 31.14)	31.08%

• Urban population rose elevenfold in the 20th century and reached about 37.7 crore in 2011. Growth rates slowed after 1981.
• Two dips: the 1911 dip came from plague and famine, and the 1961 fall in town numbers came from a stricter definition.
• India's level is low next to developed countries, but its urban population is second only to China's.
• Components of urban growth (Class 12, Geographical Perspective): natural increase, net in-migration, and reclassification of villages as towns. Rural-urban migration gave about 29% of urban growth since 1961. In 2001-11, for the first time, the urban increase (about 9.1 crore) was larger than the rural increase.
• World (UN WUP 2018): 55% urban, rising to 68% by 2050.
• States, Census 2011:
• Most urban: Goa (62.2%), then Mizoram, Tamil Nadu, Kerala, Maharashtra.
• Least urban: Himachal Pradesh (10.0%), Bihar (11.3%), Assam, Odisha.
• UTs: Delhi (97.5%) and Chandigarh (97.3%) lead.

• Largest urban population: Maharashtra, then Uttar Pradesh.

• Census 2027 has a reference date of 1 March 2027 (verify current).

6. Size classes and city systems: million-plus cities, megacities and settlement theory

Read the detailed note →

• Census size classes:

Class	Population
I	1,00,000 and above
II	50,000–99,999
III	20,000–49,999
IV	10,000–19,999
V	5,000–9,999
VI	below 5,000

About 70% of urban Indians live in Class I cities, so the system is top-heavy.

• Million-plus city (metropolitan city): a city or UA of 10 lakh or more. There were 35 in 2001 and 53 in 2011. Uttar Pradesh and Kerala had seven each.
• Megacity: a UA of 1 crore (10 million) or more. Census 2011 had three: Greater Mumbai (about 18.4 million), Delhi (about 16.3 million) and Kolkata (about 14.1 million). The UN ranks Delhi among the world's two largest (verify current).
• Central place theory (Walter Christaller, 1933): on a flat, even plain, towns form a hierarchy with hexagonal market areas. There are a few big high-order centres and many small low-order ones. This depends on two ideas for each good:
• threshold: the minimum number of buyers needed to keep it going;

• range: the farthest distance people will travel to get it.

• Rank-size rule (G.K. Zipf, 1949): the city ranked n has about 1/n of the largest city's population. India roughly fits this rule.

• Primate city (Mark Jefferson, 1939): a city more than twice the size of the next one that dominates national life, such as Bangkok, Dhaka or London. India has none at the national level. Kolkata is primate within West Bengal.
• Conurbation (Patrick Geddes, 1915): towns that have grown into each other, such as the Hugli belt.
• Megalopolis (Jean Gottmann, 1961): a chain of metro regions merged into one belt, such as Boston-Washington. Delhi-NCR and Mumbai-Pune are possible Indian cases.

7. Functional classification of towns

Read the detailed note →

• Functional classification of towns: grouping towns by their main job. Every town does many things, but many are known for one.

Class	Examples (Class 12, Human Settlements)
Administrative town (serves a higher-level capital)	Chandigarh, New Delhi, Bhopal, Shillong, Guwahati, Imphal, Srinagar, Gandhinagar, Jaipur, Chennai
Industrial town (industry is the main driving force)	Mumbai, Salem, Coimbatore, Modinagar, Jamshedpur, Hugli, Bhilai
Transport	Ports: Kandla, Kochi, Kozhikode, Visakhapatnam. Inland hubs: Agra, Dhulia, Pt. Deendayal Upadhyay Nagar (Mughalsarai), Itarsi, Katni
Commercial	Kolkata, Saharanpur, Satna
Mining	Raniganj and Jharia (coal), Digboi and Ankaleshwar (oil), Singrauli (coal)
Garrison town (military station housing troops)	Ambala, Jalandhar, Mhow, Babina, Udhampur
Educational	Roorkee, Varanasi, Aligarh, Pilani, Prayagraj
Religious and cultural	Varanasi, Mathura, Amritsar, Madurai, Puri, Ajmer, Pushkar, Tirupati, Kurukshetra, Haridwar, Ujjain
Tourist	Nainital, Mussoorie, Shimla, Pachmarhi, Jodhpur, Jaisalmer, Ooty, Mount Abu

• Most garrison towns began as British cantonments. Cantonment boards now run them under the Cantonments Act 2006.
• Key point: a town's functions change over time. As a specialised town grows into a metropolis, industry, trade, administration and transport mix together until it fits no single class. It becomes multifunctional.

8. Inside and around the city: CBD, sprawl and the peri-urban fringe

Read the detailed note →

• Central business district (CBD) (Class 12, Tertiary and Quaternary Activities): the commercial heart of a city. It has the highest land values and is the easiest place to reach. Offices, shops, banks and entertainment crowd into it. Multiplexes and restaurants locate in or near it. Uses that need a lot of land, such as golf courses, go where land is cheap.
• Bid-rent idea: land value falls as you move away from the centre. Indian examples:
• CBDs: Connaught Place, Nariman Point, Bandra-Kurla Complex.

• Newer planned business districts: GIFT City.

• Old Indian cities have a dual structure: a crowded old core around a bazaar or fort, next to colonial civil lines and cantonments.

• Urban sprawl: a city spreading out, unplanned and thinly built, into farms and villages, often along highways (ribbon development). It causes three problems:
• longer trips;
• costlier services;

• lost farmland, lakes and floodplains, as with Bengaluru's lakes, Chennai's Pallikaranai marsh, and the fringes of Hyderabad and Delhi-NCR.

• Peri-urban area: the edge zone where farms, new housing, industry and waste dumps sit side by side. It often falls between panchayat and municipal control. It takes in the city's waste and migrants and feeds the growth of census towns (Section 3) and satellite towns (Section 4).

• Other topics cover related issues:
• slums, waste and pollution: geographical-issues-problems;
• the 74th Amendment and master plans: polity's urban-local-government.

9. Sacred geography: pilgrimage towns and networks

Read the detailed note →

• Sacred geography (Class 7, How the Land Becomes Sacred): networks of holy places, routes, rivers, hills and forests that make the land itself holy.
• A tirtha is a "crossing place" from ordinary life to a higher one.
• Pilgrims have crossed the subcontinent for 3,000 years, so the whole land came to be seen as a punyakshetra (sacred land).
• Tirthas sit by rivers, at sangams (river meeting points), in forests and on hilltops. Sabarimala (Kerala) draws over ten million people a year.

• Sacred groves and Niyam Dongar (Niyamgiri, Odisha) protect nature.

• Char Dham: Badrinath (north, Uttarakhand), Dwarka (west, Gujarat), Puri (east, Odisha), Rameswaram (south, Tamil Nadu), linked to Adi Shankaracharya. It differs from the Himalayan Chhota Char Dham (Yamunotri, Gangotri, Kedarnath, Badrinath).

• Jyotirlinga: the 12 holiest Shiva shrines. They range from Somnath and Nageshwar (Gujarat) and Kedarnath (Uttarakhand) to Rameswaram (Tamil Nadu), and include Mahakaleshwar (Ujjain), Omkareshwar (on the Narmada), Kashi Vishwanath, Trimbakeshwar, Bhimashankar, Grishneshwar, Vaidyanath and Mallikarjuna (Srisailam).
• Shakti Peetha: traditionally 51 Goddess shrines where parts of Sati's body fell. They include Kamakhya (Assam), Hinglaj (Balochistan, Pakistan) and sites in Bangladesh.
• Kumbh Mela: held in rotation at four places:
• Haridwar on the Ganga;
• Prayagraj at the Triveni Sangam;
• Nashik on the Godavari;
• Ujjain on the Shipra.

It has been on UNESCO's intangible heritage list since 2017. The 2025 Prayagraj Maha Kumbh drew about 660 million people.

• Pandharpur Wari: an 800-year-old, 21-day walk of the Warkari tradition to the Vithoba temple at Pandharpur on the Bhima. The palkhis (palanquins) of Dnyaneshwar start from Alandi and those of Tukaram from Dehu.
• Link to settlements: pilgrim routes and trade routes overlapped (Uttarapatha; Dakshinapatha via Ujjain to Paithan). So tirthas grew into market towns, which is why many ancient towns are pilgrimage centres.

10. Urban policy: Smart Cities Mission, AMRUT and housing

Read the detailed note →

• Smart Cities Mission (launched 25 June 2015 by MoHUA; Class 12 box):
• Aim: core infrastructure, a clean and sustainable environment and a decent quality of life, using "smart solutions" that reduce disaster risk, use fewer resources and make services cheaper.
• Approach: develop compact areas as copyable "lighthouse" models.
• Delivery: 100 cities were chosen through a challenge competition (2016-18). Projects were area-based (retrofitting, redevelopment, greenfield) plus pan-city ICT projects. Special purpose vehicles (SPVs) ran them, and each city got an Integrated Command and Control Centre.
• The mission formally closed on 31 March 2025 (verify current).

• Critics say it served small enclaves, bypassed elected councils and spent slowly.

• AMRUT (Atal Mission for Rejuvenation and Urban Transformation, June 2015): water supply, sewerage, storm-water drains, parks and non-motorised transport in 500 cities. AMRUT 2.0 (1 October 2021) aims at tap water in all statutory towns, sewerage in the 500 AMRUT cities, and reviving water bodies.

• Pradhan Mantri Awas Yojana: housing for the poor. PMAY-Urban started in 2015. PMAY-Gramin started in 2016 and replaced Indira Awas Yojana. PMAY-U 2.0 (2024) targets 1 crore more urban homes (verify current).
• Other schemes: JNNURM (2005-14), HRIDAY (2015, heritage cities), PRASHAD (pilgrimage sites), Swachh Bharat Mission-Urban (2014; 2.0 in 2021).
• Questions to weigh: central missions vs the 74th Amendment's empowered municipalities; census towns left out of urban schemes; small towns vs metros for balanced regional growth.

Exam angles

Prelims — high-yield facts and traps

• Census urban tests: a statutory town (any urban local body) OR a census town (5,000+ people, 75% of male main workers in non-farm work, 400+ per sq km). "75% in the primary sector" is FALSE. NCERT's "and" (1991 wording) is outdated.
• Settlement type and region: clustered (Ganga plain; Rajasthan for water; Bundelkhand and Nagaland for defence); semi-clustered (Gujarat plain); hamleted (panna, para, palli, nagla, dhani; middle and lower Ganga plain, Chhattisgarh); dispersed (Meghalaya, Uttarakhand, Himachal, Kerala, north-east hills).
• Figures: 10.84% urban (1901), 17.29% (1951), 31.16% provisional / 31.14% final (2011). Peak decadal growth 46.14% (1971-81). 7,935 towns (2011). Census towns rose from 1,362 to 3,894. 53 million-plus cities and three megacities in 2011.
• Most urban state is Goa (62.2%); least is Himachal (10.0%), then Bihar (11.3%), Census 2011.
• Functional towns: mining (Digboi, Ankaleshwar, Jharia, Singrauli); garrison (Mhow, Babina, Udhampur); transport (Itarsi, Katni, Mughalsarai); educational (Roorkee, Pilani); tourist (Pachmarhi, Mount Abu).
• New towns and their states: Bhilai (Chhattisgarh), Sindri (Jharkhand), Barauni (Bihar), Durgapur (West Bengal), Dispur (Assam).
• Kumbh: Nashik on the Godavari, Ujjain on the Shipra, Haridwar on the Ganga, Prayagraj at the Sangam. On UNESCO's ICH list in 2017. Pandharpur is on the Bhima. The Char Dham sit at four corners; the Chhota Char Dham is a different set.
• Theorists: Christaller (central place, 1933), Zipf (rank-size, 1949), Jefferson (primate city, 1939), Geddes (conurbation, 1915), Gottmann (megalopolis, 1961).
• Schemes: Smart Cities Mission and AMRUT (both June 2015); PMAY-U (2015), PMAY-G (2016); AMRUT 2.0 (October 2021); the Smart Cities Mission closed on 31 March 2025 (verify current).
