Characteristics and Demographics of Migrants in India

India is home to one of the largest migrant populations in the world – and understanding who those migrants are is just as important as understanding why they move. The demographic profile of migrants in India – shaped by age, sex, marital status, and economic background – reveals deep social patterns and tells us a great deal about how development, culture, and opportunity intersect. These characteristics are not random; they reflect structured selectivity driven by both push and pull forces that vary across gender, life stage, and socioeconomic position.

The scale of migration in India

According to the Centre for Economic Data and Analysis (CEDA) at Ashoka University, as of 2020-21, about one-third of India’s total population were migrants, with this share being 34.6 percent in urban areas and 26.8 percent in rural areas. Internationally, India holds the world’s largest emigrant population, with over 18.5 million people of Indian origin living overseas as of 2024. These figures alone indicate the enormous scale of population movement – but the most compelling story lies in the demographic breakdown of who is actually migrating.

Age selectivity: why migrants skew young

One of the most consistent findings across migration research in India is that migration is strongly age-selective. The propensity to migrate is highest among young adults, particularly those in the working-age bracket. National Sample Survey (NSS) data show that more than two-thirds of international out-migrants from India belong to the 20-40 age group, reflecting the dominant motivation of employment among this cohort.

This pattern is linked to the nature of migration reasons themselves. Employment, education, and marriage are the three primary drivers of migration in India – and all three are fundamentally age-specific phenomena. As the NSSO’s Migration in India report notes, since out-migration is driven by employment, study, and marriage – all of which are age-specific activities – it is natural to expect significant variation in migration behaviour across different age groups.

Studies of migration to major urban centres like Mumbai consistently reinforce this picture. Research on Mumbai’s migration streams shows that the vast majority of migrants arrive between the ages of 15 and 30, with a pronounced concentration in the early twenties. Migration rates rise sharply after high school, peak in the mid-to-late twenties, and gradually decline thereafter – a pattern that is remarkably consistent across different cultural and regional contexts within India.

Children under 14 form a separate category: they typically migrate not of their own volition but as dependents moving with family members. At the other end of the spectrum, older-age migration does occur but remains limited. According to the 2011 Census, only 3.3% of India’s older persons migrated after the age of 60, primarily for retirement, family reunification, or healthcare-related reasons.

Sex selectivity: different streams, different reasons

The sex composition of migrants in India varies significantly depending on the type and direction of migration. At the broadest level, the 2001 Census recorded 309 million migrants based on place of last residence, of whom female migrants numbered 218 million compared to 91 million male – meaning female migrants constituted nearly 71 percent of all internal migrants. This is a striking figure, and it reflects the dominant role of marriage in driving female migration.

However, this female numerical dominance in internal migration must be understood carefully. The high number of female migrants is largely a product of India’s marriage customs rather than independent economic movement. In traditional Indian society, women are expected to relocate to their husband’s residence after marriage, with Census data showing that marriage accounts for approximately 86.8% of all female moves.

For international migration, the picture is reversed. India is one of only a handful of major origin countries where male migrants significantly outnumber female emigrants in the international out-migrant population. NSS data further reveal that among international out-migrants, women’s proportion remains almost negligible compared to men, who predominantly emigrate for employment – with around 95 percent of male emigrants citing work-related reasons.

Male-dominated labour migration is particularly concentrated in Gulf Cooperation Council (GCC) countries. While men primarily migrate to GCC countries, women are more likely to move to the USA, where Indian-origin men and women are present in nearly equal numbers – indicating that destination context shapes the gender composition of migrant streams.

Marital status and migration

Marital status is one of the most defining characteristics shaping who migrates and in which direction. For women, marriage is the single largest driver of geographic movement in India. NSS data from 1983 to 2007-08 show that about 87 percent of the rise in permanent internal migrants was due to an increasing share of female migrants, particularly those moving for marriage. Between 1993 and 2007-08, the incidence of marriage migration among rural women rose sharply from 24.7 percent to 43.5 percent.

The practice of village exogamy – where women are expected to marry outside their birth village – is especially pronounced in northern India and drives much of the rural-to-rural migration stream. Rural-to-rural migration accounts for about 53.8% of total migrants in India, where female migrants make up 63.3% of that stream – a direct reflection of marriage-led movement across village boundaries.

For men, by contrast, being unmarried or newly married often increases the propensity to migrate for work. The 2020-21 data confirm that men were most likely to move for work-related reasons while women moved primarily on account of marriage. The intersection of marriage norms and economic necessity thus creates two very distinct migration profiles along gender lines.

Economic background and who migrates

Economic background plays a complex, and sometimes counterintuitive, role in shaping migration. Findings from NSS data show that households with higher economic status – measured through Monthly Per Capita Consumer Expenditure (MPCE) quintiles – tend to have a higher number of international out-migrants. In other words, poorer households often lack the financial resources needed to finance migration, especially international movement involving travel costs, documentation, and recruitment fees.

At the same time, a majority of Indian international out-migrants come from Other Backward Classes and general caste groups, and the prevalence of out-migration is higher among Muslim households compared to Hindu households. This reflects the role of community networks, historical migration channels, and regional traditions – particularly in states like Kerala, Tamil Nadu, Andhra Pradesh, Gujarat, Goa, and Punjab – in shaping migration patterns.

For internal migrants, the educational gradient also matters. Migrants moving from rural to urban areas tend to have lower educational attainment compared to urban-to-urban migrants, and much of this rural-to-urban movement consists of unskilled or semi-skilled workers drawn to cities by informal employment opportunities in manufacturing, construction, and services.

The changing face of female economic migration

For much of India’s recorded migration history, women have been treated primarily as “associational migrants” – those who move because a male family member decided to migrate, rather than making an independent decision. This framing, while containing some empirical basis, has long obscured the economic agency of women migrants.

Research from the Institute for Social and Economic Change argues that the process of globalisation has brought about a shift in female migration patterns, with the major impetus changing from social to economic reasons. The emergence of gender-segregated labour markets – particularly in export processing zones, garment industries, domestic work, and healthcare – has created new demand for female workers, acting as a powerful pull factor.

The data on work participation rates support this shift. The work participation rate of female migrants is more than twice that of non-migrant women: while the rate for female non-migrants stands at 15 percent, it rises to 37 percent among female migrants – a striking indication that women who migrate are far more economically active than those who remain. This points to a self-selection effect: women who move independently are often doing so precisely because of economic motivations, even if they are not formally recorded as such in Census categories.

Despite these developments, the percentage of women migrating explicitly for economic reasons remains low – it actually declined from 2.6 percent to 1.1 percent between 1983 and 2007-08 in official NSS data. This apparent contradiction points to a well-known data limitation: marriage and economic migration often co-occur for women, but only the former is typically recorded as the stated reason. As social norms evolve and labour markets diversify, however, women are increasingly migrating for education, employment opportunities, and better living conditions beyond the traditional marriage route.

Regional and stream-level variations

Demographic characteristics of migrants are not uniform across India – they vary significantly by migration stream and region. In 2011, the work participation rate was highest for migrants in the 15-60 age group, while male migrants at older ages showed a higher percentage working compared to female migrants of the same age. Male work participation in migration streams was approximately 2.5 times higher than female participation in both the 2001 and 2011 censuses.

Geographically, states like Kerala, Tamil Nadu, Gujarat, and Punjab have historically contributed disproportionately to international labour migration. Working-age migrants – predominantly those in the 20 to 40 age group – supply the bulk of labour to Gulf countries, and demographic transitions now threaten to shrink this pool in southern states like Kerala, where declining fertility is rapidly ageing the population. Northern states with younger demographic profiles are increasingly stepping into the role once dominated by the south.

Within internal migration, over 87 percent of those who migrated moved within the same state, while only about 10.6 percent migrated for work-related reasons. Four in ten work migrants, however, did cross state lines – indicating that while most migration is local, economic migration has a distinctly longer reach. This inter-state labour movement is what generates the most visible demographic imbalances – young male-heavy populations arriving in destination cities, while source regions retain older residents and women in non-migrating households.

What the demographics tell us about development

The demographic profile of Indian migrants is not just a statistical exercise – it is a window into the structural dynamics of Indian society and development. The age concentration of migrants in the 15-40 range reflects the pressure on India’s young population to find livelihoods. The gender divide between internal and international migration streams exposes how deeply marriage customs and patriarchal norms shape women’s geographic mobility. The economic background data reveals that migration is not simply a response to poverty – it also requires resources, networks, and capability to act. And the growing, if undercounted, economic participation of female migrants signals a gradual but meaningful transformation in how Indian women engage with migration as a tool for advancement.

India’s status as the world’s largest migrant-origin country persists despite the presence of caste barriers, extended family arrangements, traditional values, and low nationwide levels of education – all factors that might suggest a disinclination towards mobility. That migration has grown despite these barriers is a testament to how powerful economic and social forces drive demographic change. Understanding the characteristics of migrants – age, sex, marital status, and economic background – is therefore essential for crafting policies that support migrants, protect their rights, and channel their movement toward equitable development.

What do you think? As female labour migration in India continues to grow, do the current Census categories – which still record marriage as the dominant reason for female migration – adequately capture women’s economic motivations for moving? And given that migration is most concentrated among working-age youth, what does this mean for the communities left behind – particularly older residents and children in rural source areas?
