India’s decision to launch the National Migration Survey (2026–27) marks the country’s most ambitious attempt in nearly two decades to understand how populations move, why they move, and what this means for society. Migration is not just a demographic event—it is a social process, a mechanism of inequality, and a powerful indicator of how families, labour markets, and aspirations are transforming.

From classical migration theories to contemporary perspectives on precarity and social capital, the new survey invites a deeply sociological exploration.

Migration as a Social Process: Theoretical Frameworks

Migration has been central to sociological inquiry for more than a century.

Ravenstein’s “Laws of Migration”

Ernst Ravenstein argued in the 19th century that migration is shaped by:

• economic motives,
• short-distance movements,
• rural–urban shifts, and
• gendered patterns.

His key observation—that women migrate more for social reasons (marriage)—is remarkably visible in India, where 87% of female migration is marriage-led, according to PLFS (2020–21).

Everett Lee’s Push–Pull Theory

Lee’s framework helps contextualize India’s post-Covid mobility:

• Push factors: rural distress, job scarcity, climate disruptions.
• Pull factors: urban wages, education, services, and opportunities.
• Intervening obstacles: caste discrimination, unsafe travel, housing shortages, lack of documentation.

The upcoming survey’s focus on short-term migration, access to services, and future mobility plans aligns perfectly with Lee’s model.

Zelinsky’s Mobility Transition Theory

Wilbur Zelinsky argued that migration increases as societies industrialise.
India’s shift from agrarian to service and manufacturing economies mirrors this transition—but unevenly:

• high mobility in southern and western states,
• stagnation and distress-driven migration in central-eastern India.

Why the National Migration Survey Matters Sociologically

1. Migration Reflects Inequality and Social Stratification

Migration is not an equal-opportunity phenomenon.
Caste, class, gender, religion, and region shape who moves, where they move, and how vulnerable they are.

Jan Breman’s work on footloose labour shows how migrant workers exist in a system of circulatory labour, trapped in low wages and high insecurity.
The new survey’s inclusion of income changes and living conditions will help expose these stratifications.

2. Migration is a Survival Strategy in Rural India

For millions, mobility is a strategy to cope with:

• agrarian distress,
• water scarcity,
• landlessness,
• climate vulnerabilities.

This resonates with A.R. Desai’s analysis of rural transformation under capitalism and the shift of peasants into wage labour.

3. The Feminisation of Migration

Though male migration is often highlighted in popular narratives, Indian data shows:

• Women migrate more than men (28.9% overall rate, with female rates nearly 8× higher in rural areas).

While most women migrate due to marriage, an emerging trend of female educational and employment migration—especially among the urban poor—reflects changing gender norms.

4. Internal Migration Shapes Urban Sociology

Cities like Delhi, Mumbai, Surat, and Bengaluru are built and sustained by migrants.
Manuel Castells’ idea of the “Network Society” helps explain why cities attract young workers—digital connectivity, service jobs, and globalised economies serve as powerful pull factors.

The migration survey will assist urban planners in understanding:

• slum growth,
• rental housing pressures,
• transport needs,
• informal employment networks.

Understanding the New Survey Through Sociology

1. Individual, Not Household-Level Data

Tracking individual migrants aligns with modern sociological understanding that:

• migration decisions are often individual agency,
• families are increasingly fragmented,
• work is precarious and mobile (Standing’s “precariat”).

2. Redefining Short-Term Migration

The new definition (15 days to <6 months) will capture:

• seasonal migrants,
• construction workers,
• sugarcane cutters,
• brick-kiln labourers,
• urban gig workers.

Short-term migration is critical in India but has long remained statistically invisible.

3. Fresh Insights on Access to Services

By adding questions on:

• health services,
• ration portability,
• education continuity,
• social protection,

the survey aligns with Amartya Sen’s capabilities approach, which assesses well-being beyond income.

4. Capturing Future Intentions

Understanding whether migrants intend to return, settle, or re-migrate provides insight into:

• urban integration,
• stability of work,
• aspirations and social mobility.

This links to Bourdieu’s concept of habitus—migration decisions reflect internalised hopes, fears, and cultural expectations.

Historical Context: Migration Surveys Since 1955

Since the 9th round of the NSS, India has periodically studied migration, but only two rounds—18th (1963–64) and 64th (2007–08)—were comprehensive.
After 2007–08, India changed dramatically:

• urbanisation accelerated,
• informal work expanded,
• gig economy emerged,
• Covid-19 created the largest reverse migration since Partition.

The 2026–27 survey arrives at a crucial moment when mobility patterns have fundamentally shifted.

Migration and Gender: A Sociological Re-examination

Indian migration is deeply gendered.

Marriage Migration and Patriarchal Structures

Scholars like Leela Dube and Patricia Uberoi have shown how kinship systems dictate women’s movement.
Marriage migration shows:

• patrilocal residence norms,
• women uprooted from maternal support systems,
• restricted autonomy in new households.

Men’s Work Migration

Male migration reflects:

• regional inequalities,
• labour-market segmentation (Breman),
• caste-based occupational networks.

These networks form what sociologists call social capital, facilitating movement and job access.

Urban Integration: The New Frontier

The role of migrants in India’s cities is often paradoxical:

• Cities depend on their labour but
• exclude them from housing, healthcare, and welfare.

This exclusion resembles Saskia Sassen’s “global city” theory, where migrants sustain globalised economies but remain socially marginalised.

The new survey’s data will help uncover:

• informal settlement patterns,
• access to public services,
• exclusion in rental markets,
• occupational vulnerability.

Significance of the Survey for Social Policy

1. Identifying Migration Corridors

The survey will help map:

• Bihar–Delhi,
• Odisha–Gujarat,
• UP–Mumbai,
• Jharkhand–Bengaluru,

revealing how labour circulates across India.

2. Monitoring Social Protection

Understanding migrant workers’ access to:

• ration cards,
• health insurance,
• pensions,
• portability schemes (like One Nation One Ration Card)

will significantly improve welfare programme design.

3. Urban Expansion and Housing Policy

Cities need:

• rental housing models,
• migrant hostels,
• safe women’s accommodation,
• improved slum services.

4. Labour Market Planning

India’s demographic dividend depends on matching migrant skills to labour demand—a core insight of labour sociologists like K.T. Merchant and Jan Breman.

Conclusion: Migration Is the Story of Social Change

The National Migration Survey 2026–27 represents more than a statistical exercise—it is a study of India’s social transformation.

Migration tells us:

• how households cope with crisis,
• how youth imagine the future,
• how cities grow,
• how inequalities shift,
• how gender relations evolve,
• how work becomes precarious or empowering.

Through the lenses of Ravenstein, Lee, Zelinsky, Bourdieu, Fraser, Breman, and contemporary Indian scholars, migration emerges not just as movement but as a mirror of our society’s deepest structures.

The 2026–27 survey will finally give India the empirical foundation needed to connect policy with the complexities of social life—and to understand how mobility shapes the nation’s future.
