Migration: Types, Streams, Causes and Consequences
Migration in India for CGPSC: census definitions, Census 2011 and PLFS 2020-21 data, streams, reasons, Ravenstein and Lee, remittances, policy and Chhattisgarh.
Prerequisites
- Census 2011 Highlights: growth and regional differences that drive movement
- Population Composition: sex ratio and work, both shaped by migration
- Poverty, Unemployment and Inclusive Growth: the economic push behind much labour migration
The Hook: After the Harvest
Connect
Every year, once the paddy is harvested in the plains of Chhattisgarh, families lock their houses, board trains at Bilaspur or Raipur and leave for brick kilns and construction sites in other states. They return before the next monsoon to sow again. In the spring of 2020, during the COVID-19 lockdown, the whole country saw such workers walking hundreds of kilometres home.
Yet the census says the most common reason Indians migrate is not work at all. Who migrates in India, where, why, and with what effects?
Why it matters: Prelims tests definitions and the “largest reason / largest stream” facts. Mains GS-III asks for causes and consequences of migration and, increasingly, for policy on migrant workers, with Chhattisgarh’s seasonal migration as the obvious local example.
What Counts as Migration (प्रवास)
Migration is the movement of people from one place to another with a change of usual residence. The census records it in two ways:
| Basis | Definition | Use |
|---|---|---|
| Place of birth (POB) | A person counted at a place other than where they were born | Lifetime migration |
| Place of last residence (POLR) | A person whose place of last residence differs from the place of enumeration | Better for recent movements and for reasons; the standard basis for analysis |
Types and streams
| By distance | By direction (streams) |
|---|---|
| Intra-district (within the same district) | Rural to rural |
| Inter-district, within the state | Rural to urban |
| Inter-state | Urban to urban |
| International (immigration and emigration) | Urban to rural |
By duration, migration can also be permanent, semi-permanent, seasonal or circular (moving for a season and returning, like Chhattisgarh’s brick-kiln workers) or daily commuting.
The Data
Census 2011 (migration tables released in 2019)
| Fact | Detail |
|---|---|
| Migrants by last residence | 45.58 crore, about 37.6% of the population |
| Census 2001 | 31.45 crore, about 31% |
| Who migrates | Women are the large majority of migrants, mainly because of marriage |
| Leading reason overall | Marriage, accounting for close to half of all migrants |
| Leading reason for men | Work and employment |
| Distance | Most migrants move within their own state, many within the same district; inter-state migrants are a minority |
| Largest stream | Rural to rural, dominated by women moving on marriage |
| Main source states (inter-state) | Uttar Pradesh and Bihar |
| Main destination states | Maharashtra, Delhi, Gujarat and other industrial and urban regions |
PLFS: Migration in India 2020–21
MoSPI’s Periodic Labour Force Survey (July 2020–June 2021) included a migration module, released in June 2022:
| Fact | Detail |
|---|---|
| Migration rate (all India) | 28.9% |
| Rural / urban | 26.5% / 34.9% |
| Female / male | about 48% / 10.7% |
| Leading reason for female migrants | Marriage (86.8%) |
Other estimates
- The Economic Survey 2016–17 used railway passenger data to estimate inter-state migration at about 9 million people a year between 2011 and 2016, much higher than earlier census-based estimates.
- A 2024 working paper of the Economic Advisory Council to the Prime Minister (EAC-PM) estimated about 40 crore domestic migrants in 2023, about 12% fewer than in 2011. It linked this to better services and opportunities closer to home. Treat it as an estimate, not a census figure.
Why women dominate the migration figures
In India, women usually move to the husband’s home on marriage (patrilocal residence), most often to a nearby village. This single custom makes rural-to-rural, short-distance, female, marriage-led migration the biggest category in every census. Labour migration, which dominates the news, is mostly male and longer-distance, and it is under-counted because seasonal workers often report their home village as their usual residence.
Why People Migrate: Push and Pull
| Push factors (from origin) | Pull factors (to destination) |
|---|---|
| Poverty, low wages, small and unirrigated holdings | Jobs and higher wages in industry, construction and services |
| Drought, floods, crop failure | Better education and health facilities |
| Lack of non-farm work after the harvest | Urban amenities, social networks of earlier migrants |
| Debt, landlessness, displacement by dams and mines | Security, social freedom (weaker caste control in cities) |
| Conflict and insecurity (e.g. Left-Wing Extremism areas) | Marriage, family reunion |
Theories of migration
| Theory | Key idea |
|---|---|
| Ravenstein’s Laws of Migration (1885, based on British census data) | Most migrants move short distances; migration proceeds step by step; long-distance migrants go to big commercial and industrial centres; every stream produces a counter-stream; townspeople migrate less than rural people; women migrate more than men over short distances; economic motives dominate |
| Lee’s push–pull model (Everett Lee, 1966) | Migration results from factors at origin, factors at destination, intervening obstacles (distance, cost, laws, language) and personal factors |
| Zelinsky’s mobility transition (1971) | Types of mobility change as a society passes through the demographic transition |
| Todaro model (1969) | Rural-to-urban migration responds to expected urban income (wage times the probability of getting a job), which explains why people keep moving even when urban unemployment is high |
Consequences of Migration
| Area | Positive | Negative |
|---|---|---|
| Economic | Remittances support rural households; labour for industry, construction and services; skills brought home | Ageing, female-headed farms at origin; informal, insecure jobs; exploitation by contractors; pressure on urban services |
| Demographic | Redistributes population | Distorts sex ratios (male-heavy cities and industrial towns, female-heavy origin villages); changes age structure |
| Social | Exposure to new ideas, weakening of caste rigidity, cultural mixing | Anonymity, social exclusion, children’s schooling interrupted by seasonal moves, conflicts over “sons of the soil” |
| Environmental | — | Unplanned urban growth, slums, overcrowding, water and waste stress |
International migration and remittances
- India is the world’s largest country of origin of international migrants. About 18.5 million Indians lived abroad in 2024 (UN estimate), roughly half of them in the Gulf countries.
- India is the largest recipient of remittances in the world: about USD 129 billion in 2024 (World Bank estimate). RBI data put inflows at a record USD 135.46 billion in 2024–25.
- Kerala is the classic example of a remittance-driven state economy (the “Gulf boom”).
Policy for Migrant Workers
| Measure | Detail |
|---|---|
| Inter-State Migrant Workmen Act, 1979 | Registration of contractors, displacement allowance, journey allowance. It has been subsumed in the Occupational Safety, Health and Working Conditions Code, 2020 |
| Four Labour Codes | All four codes came into force on 21 November 2025, replacing 29 central labour laws; supporting central and state rules were still being notified at the time |
| e-Shram portal (2021) | National database of unorganised workers, including migrants, for social-security delivery |
| One Nation One Ration Card | Portability of food rations under the National Food Security Act, so migrants can draw rations anywhere |
| Affordable Rental Housing Complexes (2020) | Rental housing for urban migrants and the poor, a sub-scheme of PMAY-Urban, launched after the 2020 lockdown |
| Rural employment guarantee (MGNREGA; VB-G RAM G from 1 July 2026, 125 days) | Wage employment in the village; reduces distress migration in lean seasons |
Chhattisgarh angle for Mains
- Out-migration: seasonal labour migration from the central plains after the kharif paddy harvest to brick kilns, construction sites and farms in other states is long established. Debt-linked advances from labour contractors can turn into bonded labour, and rescues of Chhattisgarhi workers from kilns in other states regularly make the news.
- Historical roots: under colonial rule, the railway carried Chhattisgarhi labour to coalfields and the tea gardens of Assam (see Administrative Reforms and Railways).
- In-migration: the Raipur–Durg–Bhilai corridor, Korba and Bilaspur draw workers from within and outside the state; industrial districts such as Korba show lower sex ratios as a result.
- Displacement-led migration: mining and dam projects, and conflict in parts of Bastar, have displaced tribal families.
- Policy levers: the rural employment guarantee (VB-G RAM G, which replaced MGNREGA from July 2026), paddy procurement at support prices, the public distribution system and registration of workers can reduce distress migration.
Memory Tricks
'Women, Weddings, Within'
The biggest migration category in India is Women moving for Weddings Within the state (rural to rural, short distance). Labour migration is the smaller, male, longer-distance stream.
Ravenstein = 'Short, Steps, Streams'
Migrants move Short distances, in Steps, and every Stream has a counter-stream. Add “women move more over short distances”.
Lee's four boxes
Origin, Destination, Obstacles, Person: “ODOP”, like the one-district-one-product scheme.
Don’t Confuse
| This | vs | That |
|---|---|---|
| Place of birth (lifetime migration) | vs | Place of last residence (recent migration, reasons) |
| Census 2011 migrants 45.58 crore (about 37.6%) | vs | PLFS 2020–21 migration rate 28.9% (a survey, different definitions) |
| Top reason overall: marriage | vs | Top reason for men: work |
| Largest stream: rural to rural | vs | Most-discussed stream: rural to urban |
| Ravenstein (1885): laws of migration | vs | Lee (1966): push–pull with intervening obstacles |
| Inter-State Migrant Workmen Act 1979 | vs | Now part of the OSH Code 2020 (in force from 21 November 2025) |
Common Mistakes
Trap 1: 'Most Indians migrate for employment'
False for the population as a whole. Marriage is the leading reason overall (and for women); employment is the leading reason for men.
Trap 2: 'Rural-to-urban is the largest stream'
False. Rural to rural is the largest stream in the census, because of marriage migration of women.
Trap 3: 'Most migrants cross state borders'
False. Most migrants move within their own state, often within the same district. Inter-state migrants are a minority, though their number is large in absolute terms.
Trap 4: mixing survey and census figures
Census 2011 (about 37.6% migrants) and PLFS 2020–21 (28.9% migration rate) use different methods and periods. Do not combine them into a “trend”.
Practice
All questions below are original practice questions in CGPSC style. They are not previous-year questions.
Level 1: Foundation
- The two bases on which the census records migration are place of ________ and place of ________.
- According to Census 2011, the single most important reason for migration in India was ________.
- The model of migration that adds “intervening obstacles” to push and pull factors was proposed by ________.
Answers
- Birth; last residence
- Marriage
- Everett Lee (1966)
Level 2: Prelims MCQs
Q1. Consider the following statements about internal migration in India as per Census 2011:
- Rural-to-rural migration was the largest migration stream.
- A majority of migrants moved across state boundaries.
- Female migrants outnumbered male migrants.
Which of the statements given above is/are correct?
- (a) 1 only
- (b) 1 and 3 only
- (c) 2 and 3 only
- (d) 1, 2 and 3
Answer and explanation
(b) 1 and 3 only. Rural-to-rural, short-distance migration by women on marriage dominates the census figures, so 1 and 3 are correct. Statement 2 is wrong: most migrants move within their own state.
Q2. Match List I (Thinker or model) with List II (Idea):
| List I | List II |
|---|---|
| A. E.G. Ravenstein | 1. Migration responds to expected, not actual, urban income |
| B. Everett Lee | 2. Every migration stream produces a counter-stream |
| C. Wilbur Zelinsky | 3. Intervening obstacles between origin and destination |
| D. Michael Todaro | 4. Mobility transition linked to the demographic transition |
- (a) A-2, B-3, C-4, D-1
- (b) A-3, B-2, C-4, D-1
- (c) A-2, B-3, C-1, D-4
- (d) A-2, B-4, C-3, D-1
Answer and explanation
(a) A-2, B-3, C-4, D-1. Ravenstein’s laws (1885) include the counter-stream; Lee (1966) added intervening obstacles; Zelinsky (1971) proposed the mobility transition; Todaro (1969) explained rural–urban migration by expected income.
Q3. According to the PLFS report “Migration in India 2020–21”, the all-India migration rate was about:
- (a) 18.6%
- (b) 28.9%
- (c) 37.6%
- (d) 45.6%
Answer and explanation
(b) 28.9%. The rate was 26.5% in rural and 34.9% in urban areas, and about 48% for women against 10.7% for men. Option (c) is close to the Census 2011 share of migrants and (d) is the Census 2011 number in crore, both distractors.
Q4. The Inter-State Migrant Workmen (Regulation of Employment and Conditions of Service) Act, 1979 has been subsumed in which of the following?
- (a) The Code on Wages, 2019
- (b) The Industrial Relations Code, 2020
- (c) The Occupational Safety, Health and Working Conditions Code, 2020
- (d) The Code on Social Security, 2020
Answer and explanation
(c). The OSH Code, 2020 covers inter-state migrant workers, including provisions such as a journey allowance. All four labour codes came into force on 21 November 2025.
Level 3: Mains Answer Writing
Q1. (60 words) Distinguish between push and pull factors of migration with two examples each.
Model answer outline
- Push factors act at the origin and drive people out: poverty and lack of non-farm work (e.g. after the paddy harvest in Chhattisgarh), drought or displacement by mines and dams.
- Pull factors act at the destination and attract people: jobs and higher wages (construction in Delhi or Mumbai), better education and health facilities.
- Note: Lee (1966) adds intervening obstacles and personal factors.
Q2. (150–200 words) Examine the causes and consequences of seasonal labour migration from Chhattisgarh. Suggest measures to reduce distress migration.
Model answer outline
- Intro: circular migration after the kharif harvest from the central plains to brick kilns, construction and farms in other states; India’s largest migration stream is marriage-led, but labour migration is the policy concern.
- Causes: single-crop rain-fed agriculture, small holdings, lack of non-farm jobs, debt and contractor advances, wage gaps between states, established networks.
- Consequences: remittances and debt repayment; but bonded-labour risk, unsafe work, children’s schooling broken, exclusion from rations and welfare at the destination, health risks; ageing and feminised farms at home.
- Measures: irrigation and second crops; rural employment guarantee work in lean seasons (VB-G RAM G from July 2026); registration on e-Shram and source-destination labour cooperation; ration portability (One Nation One Ration Card); seasonal hostels so children stay in school; enforcement of the OSH Code; skilling and local industry (food processing, minor forest produce).
- Conclusion: the aim is to make migration a choice, not a compulsion.
