Functional classification of towns

Detail

1. What functional classification means

• Functional classification of towns means grouping towns by their main job (function). Examples of a main job are ruling, making goods, trade or defence.
• Every town does many jobs: trade, transport, administration and services. Many towns are still known for one job above the rest.
• Central place: a town that gives goods and services to the villages and smaller towns around it. Most towns are central places. Many also specialise, which means they become known for one special job.
• Two ways to classify:
• Qualitative (NCERT method): a town is placed in a class because of its best-known job, such as Jamshedpur for steel or Haridwar for pilgrimage.
• Quantitative: the class comes from the share of workers in each sector. The Census groups workers by industrial category. Examples are mining and quarrying, manufacturing, wholesale and retail trade, transportation and storage, public administration and defence, education, and accommodation and food services [5]. A town gets its class from the sector that employs an unusually large share of its workers.

2. The nine functional classes

Class	Meaning	Examples (state)

Tourist town	Grows on visitors who come for scenery, cool climate or heritage	Nainital, Mussoorie (Uttarakhand); Shimla (Himachal Pradesh); Pachmarhi (MP); Jodhpur, Jaisalmer, Mount Abu (Rajasthan); Udhagamandalam/Ooty (Tamil Nadu)

3. Notes on each class

• Administrative towns
• Chandigarh and Gandhinagar were planned capitals built after Independence. Chandigarh serves two states, Punjab and Haryana.

• Older capitals such as Jaipur and Chennai later took on trade and industry as well.

• Industrial towns

• Raw material, power and transport pull factories to a place, and the factories pull in workers. The result is a town built around a plant.

• Jamshedpur and Bhilai grew around steel plants. Hugli grew on jute mills along the Hugli river. Coimbatore grew on cotton textiles. Modinagar grew around one industrial group's factories.

• Transport towns

• Ports grew where land meets sea trade. Kandla is on the Gulf of Kachchh on the west coast. Visakhapatnam is on the east coast, facing the Bay of Bengal.

• Inland hubs are railway or road junctions where many lines meet. Itarsi and Katni (MP) are rail junctions in central India, and Mughalsarai links north India with the east.

• Mining towns

• Raniganj and Jharia are in the Damodar valley coalfields. Singrauli is a coal and thermal power belt on the MP–UP border.

• Digboi in upper Assam is India's oldest oilfield town. Ankaleshwar is an oilfield in the Gujarat (Cambay) basin.

• Garrison towns and cantonments

• Cantonment: an area set apart to house troops, with a separate local government.
• Most garrison towns began as British cantonments. Today cantonment boards run them under the Cantonments Act, 2006. The Act aims at more democracy in these boards, a better financial base and development work [2].
• A Cantonment Board is a body corporate with perpetual succession. This means it is a legal body that continues even when its members change [2].

• Four categories by population [2]:

  Category	Population
  I	above 50,000
  II	above 10,000 up to 50,000
  III	above 2,500 up to 10,000
  IV	up to 2,500

• India has 62 cantonments in 19 states, counting NCT of Delhi (PIB) [3]. The Directorate General of Defence Estates (Ministry of Defence) oversees them [4].

• Recent change (2023): the government decided to excise (cut out) the civil areas of cantonments and merge them with nearby state municipalities. This gives them the same municipal laws as the towns around them. Plans for 58 cantonments were shared with state governments. Khas Yol cantonment (Himachal Pradesh) was de-notified from 27 April 2023 [6].

• Educational towns

• Roorkee, Aligarh and Pilani grew around one major institution. A campus brings in students and staff, then services follow, and a town forms.

• Religious and cultural towns

• Many of these are ancient towns. Varanasi and Prayagraj are on the Ganga (Prayagraj at the Ganga–Yamuna confluence). Madurai is on the Vaigai and grew around the Meenakshi temple. Ujjain is on the Shipra.

• Varanasi appears in three classes: educational, religious and cultural. Prayagraj appears in two: educational, and administrative or religious.

• Tourist towns

• Shimla, Mussoorie, Nainital, Ooty, Pachmarhi and Mount Abu are hill stations. The British set them up as summer retreats from the hot plains. This makes them colonial-era towns.
• Pachmarhi is in the Satpura range, Mount Abu in the Aravallis and Ooty in the Nilgiris.
• Jodhpur and Jaisalmer in the Thar Desert draw visitors for forts and heritage.

4. Functions change over time: multifunctional cities

• Key idea: a town's functions are dynamic, which means they change over time.
• How a specialised town becomes multifunctional:
• It starts with one job, such as a port or a factory.
• As it grows into a metropolis (a very large city), trade, banking, administration and transport gather around that first job.

• In the end all these jobs are so mixed together that the city fits no single class. It becomes multifunctional.

• Examples: Mumbai began as a port and is now also an industrial, financial and administrative centre. Kolkata began as a commercial and port city and is now also an administrative and industrial city. Chennai fits the same pattern.

• Map practice: mark each example town on an outline map of India with its state.

Prelims Hooks

• Digboi (Assam) and Ankaleshwar (Gujarat) are oil mining towns. Raniganj, Jharia and Singrauli are coal towns.
• Pt. Deendayal Upadhyay Nagar is the new name of Mughalsarai (UP), an inland transport hub. Itarsi and Katni (both MP) are also inland transport hubs.
• Mhow (MP), Babina (UP) and Udhampur (J&K) are garrison towns, not tourist towns.
• Kozhikode and Kochi (both Kerala) are listed as port transport towns. Kandla is a port on the Gulf of Kachchh.
• Satna (MP) and Saharanpur (UP) are commercial towns. Salem and Modinagar are industrial towns.
• Cantonments Act, 2006: there are 4 categories of cantonment by population. Category I is above 50,000 [2]. India has 62 cantonments in 19 states including Delhi [3].
• Khas Yol (Himachal Pradesh) cantonment was de-notified with effect from 27 April 2023 [6].
• Pilani (Rajasthan) and Roorkee (Uttarakhand) are educational towns. Pushkar and Ajmer (Rajasthan) are religious towns. Mount Abu (Rajasthan) is a tourist town.
• Trap: Varanasi fits both the educational and the religious class. Prayagraj fits the educational class and is also an ancient religious town.

Mains Points

• Functions are dynamic (GS-I): specialised towns that grow into metros, such as Mumbai, Kolkata and Chennai, become multifunctional. This makes single-label classification less useful for big cities. Quantitative classification by the share of workers in each sector, using Census industrial categories [5], is a more exact tool.
• Colonial imprint on India's towns: cantonments, hill stations (Shimla, Ooty, Mussoorie) and port cities (Kolkata, Chennai, Mumbai) show how British needs of defence, summer retreats and trade shaped India's town pattern. That legacy still shapes how these towns are governed.
• Cantonment governance reform (GS-I/II): civil populations live under cantonment boards while the towns around them have elected municipalities. This leads to unequal services and rules. The 2023 plan to cut out civil areas from 58 cantonments and merge them with state municipalities, starting with Khas Yol [6], tries to bring uniformity. It depends on agreement from the state governments.
• Single-function towns are vulnerable: mining towns (Jharia, Digboi) and one-plant industrial towns (Bhilai, Modinagar) decline when the resource runs out or the plant shuts. Planning should spread their economy across more sectors.
