Doing Sociology: Research Methods

Why this chapter matters for UPSC: Every GS answer that cites a Census figure, a sample survey or a field study rests on the methods this chapter explains. NCERT's last chapter asks what makes a sociologist different from anyone else who knows about society, and answers: method, the way knowledge is acquired. It explains why objectivity is harder in sociology than in the natural sciences and how reflexivity helps, why sociology uses many methods, and how three of them work: participant observation, the survey and the interview. It also explains why a scientifically chosen sample of a fraction of one per cent can stand for a billion people, and why some problems, such as a falling child sex ratio, become visible only in aggregate statistics. The chapter is unchanged in the 2026-27 reprint (word-for-word the 2021-22 text), so its box on the census and the National Statistical Organisation predates Census 2027 and the redesigned labour survey; this page sets those details out with dates.

Contemporary hook: India's next census is being taken now. Census 2027 runs in two phases: houselisting and housing between April and September 2026, and population enumeration in February 2027 (September 2026 in Ladakh and the snow-bound areas of Jammu and Kashmir, Himachal Pradesh and Uttarakhand). Its reference date, the "census moment", is 00:00 hours on 1 March 2027, except 1 October 2026 for Ladakh and those snow-bound areas and 5 January 2027 for Goa, Uttar Pradesh, Punjab and the rest of Uttarakhand. It is the first census taken by digital means, with an optional 15-day self-enumeration window, and, following the Cabinet Committee on Political Affairs decision of 30 April 2025, it will enumerate castes, which until 2011 the census did systematically only for Scheduled Castes and Scheduled Tribes (PIB backgrounder, April 2026; Registrar General's notification S.O. 4919(E), 5 September 2026).

🧠 First Principles — Read This First

Method is what makes sociology a science. All of us live in society and know a lot about groups, institutions and norms from experience. Sociologists can claim to differ from lay persons "not because of how much they know or what they know, but because of how they acquire their knowledge". Sociology also wants both the outsider's view (what a bystander can observe) and the insider's view (what friendship means to people in a culture, what a worshipper thinks a ritual does, how a shopkeeper and customer read each other while bargaining), and capturing both needs careful method.

Objectivity is a process, not a possession. A geologist is not part of the rocks she studies; a sociologist is part of the society she studies, with its likes, dislikes and prejudices. There are also many versions of the "truth" in the social world, and sociology itself is "multi-paradigmatic", with competing schools of thought. So the old ideal of an "objective, disinterested" social science is widely considered outdated. That does not make sociology useless: objectivity becomes "the goal of a continuous, ongoing process rather than an already achieved end result", pursued through self-reflexivity and careful documentation.

No method is best in general; a method is right for a question. "There is no single unique road to sociological truth." Each method has strengths and weaknesses, so it is "futile to argue about the superiority or inferiority of different methods". What matters is whether the method fits the question. To find whether most Indian families are still joint families, a census or survey is best; to compare the status of women in joint and nuclear families, interviews, case studies or participant observation may all be appropriate.

PART 1 — Quick Reference

Three Methods Compared (NCERT)

Ways of Classifying Methods

NCERT stresses that any such classification "is a matter of convention": the lines are not sharp, methods can be converted or combined, and the choice depends on the research question, the researcher's preferences and limits of time and resources. The recent trend is to use multiple methods on the same problem, triangulation: "a process of reiterating or pinpointing something from different directions".

Classic Fieldwork (NCERT's examples)

PART 2 — Concepts & Narrative

Method and Methodology

"Methodology", often used as a synonym for method, actually means the study of method. Methodological questions concern the general problems of scientific knowledge-gathering that go beyond any one technique, starting with how sociologists try to produce knowledge that can claim to be scientific.

Objectivity and Subjectivity in Sociology

In everyday language "objective" means unbiased, neutral, based on facts alone, and "subjective" means based on individual values and preferences. Every science is expected to be objective, but this is much harder in the social sciences. A geologist or botanist must keep personal preferences, including a liking for a theory, out of her results, but she is not part of the world of rocks or plants. Social scientists study the social world they live in. First there is the obvious problem of bias: a sociologist studying family relations is herself a member of a family, and one studying a caste or religious community other than her own may be influenced by attitudes to that community in her own social environment.

A second problem is that there are "many versions of the 'truth' in the social world": a shopkeeper and a customer differ on what a good price is, a young and an old person on what good food is. There is no simple way of judging which interpretation is truer, and sociology tries not to judge this way, because it is interested in what people think and why. A third complication is that sociology, like its sister sciences, is multi-paradigmatic: competing, mutually incompatible schools of thought coexist (chapter 2's functionalist and conflict theories). Hence NCERT's conclusion that objectivity must be "the goal of a continuous, ongoing process".

Multiple Methods and the Choice of Method

Because there are multiple truths and perspectives, there are multiple methods, each suited to some questions and not others (see the classification table in Part 1). NCERT concentrates on the methods most distinctive of sociology, those that produce primary data, and within fieldwork-based methods on three: participant observation, the survey and the interview.

Participant Observation

Popular in sociology and especially social anthropology, participant observation differs from surveys and interviews because it involves a long period of interaction with the people studied: typically many months, usually about a year or more, living among them "as one of them". The non-native outsider immerses herself in the culture by learning the language and participating intimately in everyday life, to acquire the explicit and implicit knowledge of the insider. The overall goal is to learn about the "whole way of life" of a community, and the model is the child: researchers are supposed to learn everything about their adoptive community in the holistic way small children learn about the world. Participant observation is often called fieldwork, a term taken from natural sciences such as botany, zoology and geology, whose scientists had to go out into "the field".

Fieldwork in Social Anthropology

Fieldwork as a rigorous scientific method played a major role in establishing anthropology as a social science. The early anthropologists were "armchair scholars" who organised information about distant communities they had never visited, taken from the reports of travellers, missionaries, colonial administrators and soldiers: James Frazer's The Golden Bough rested entirely on such second-hand accounts, and so did Emile Durkheim's work on primitive religion. From the end of the 19th century some anthropologists, several of them natural scientists by profession, began systematic first-hand observation; reliance on second-hand accounts came to be thought unscholarly, and since the 1920s participant observation has been an integral part of anthropological training and its principal method. Many places became famous in the discipline through classic fieldwork.

The fieldworker usually begins with a census of the community (everyone who lives there, with sex, age group and family), perhaps with a map of the settlement, houses and socially relevant sites. A key early technique is the genealogy: a family tree for each household extended as far back as people remember, built by asking the head of household about relatives in his or her own generation, then parents' and grandparents' generations, and cross-checked with other relatives. It reveals the kinship system and practically introduces the researcher to people. Building on this, the anthropologist keeps learning the language, observes festivals, collective events, ways of earning a living, family relations and child rearing, and asks "endless questions" about things the community takes for granted. Most information comes from one or two people, the informants or principal informants (once called "native informants"), who act as the anthropologist's teachers. Equally important are field notes, written up every day without fail, often with a daily diary.

Malinowski and the "invention" of fieldwork. NCERT's box says that Bronislaw Malinowski, a Polish anthropologist settled in Britain, is widely believed to have established fieldwork as the distinctive method of social anthropology, though he was not the first to use it. When the First World War broke out in 1914 he was in Australia and became technically an "enemy alien", so the law required him to be confined to a specific place; at his request the authorities let him serve this in the Trobriand Islands, which NCERT calls "a British-Australian possession" in the South Pacific, and even financed the trip. He lived for a year and a half in a tent in native villages, learnt the language, kept careful records and a daily diary, and wrote books that became classics. Already convinced that anthropology would stay an intellectual hobby unless researchers observed directly, in context, after intensive language learning and without interpreters, he used his position at the London School of Economics to make fieldwork mandatory in anthropological training.

Fieldwork in Sociology

Sociologists use much the same techniques; their fieldwork differs less in content than in context and emphasis. They too try to become insiders, but among all sorts of communities, not only remote tribes, and they need not "live in", though they spend most of their time with the people studied. William Foote Whyte lived for three and a half years in an Italian-American slum in a large American city, "hanging out" with a street gang of mostly poor, unemployed youths, the first American-born generation of an immigrant community, and wrote Street Corner Society. His own note on the difficulties shows how sociological fieldwork differs: he was dealing with a literate people who would read his report; disguising the district's name might fool outsiders, but the people there would recognise themselves and each other "with little chance of error", so the researcher "carries a heavy responsibility" to minimise harm. Fieldwork can take other forms too: Michael Burawoy worked for several months as a machinist in a Chicago factory to write about work from the workers' perspective.

Village Studies in India

In Indian sociology fieldwork was used above all in village studies. From the 1950s many Indian and foreign anthropologists and sociologists studied village life. The village was the equivalent of the anthropologist's tribal community: a "bounded community" small enough for one person to know almost everyone. There were other reasons. Anthropology was unpopular with nationalists in colonial India for its excessive concern with the "primitive" and its colonial bias, emphasising the non-modern side of colonised societies; questions were being asked about its links with colonialism, since classic fieldwork like Malinowski's and Evans-Pritchard's was made possible by colonial empires. More than methodology, the village was of great interest in newly independent India: the government wanted to develop rural India, the national movement and Mahatma Gandhi had promoted "village uplift" programmes, even urban educated Indians kept family links with villages, and above all villages were where most Indians lived "(and still do)". NCERT's box describes different styles of village study: the Wisers' missionary study, Srinivas's classical single-researcher fieldwork, Dube's development-oriented team project at Shamirpet, and the multidisciplinary Cornell project (see the table in Part 1).

Limitations of Participant Observation

Fieldwork's great strength is the insider's perspective, the return on a large investment of time; it allows correction of first impressions and observation of change and of different contexts, and so avoids many errors of short surveys and questionnaires. But it involves long, intensive research usually by a single scholar, covering only a single village or small community, so we cannot be sure whether what was observed is common or exceptional: "This is probably the biggest disadvantage of field work." We also cannot be sure whether we hear the people's voice or the anthropologist's, who may consciously or unconsciously select what to record, and since no other version exists, bias or error cannot be checked (a risk present in most methods). More generally, fieldwork rests on a one-sided relationship in which the researcher asks the questions and "speaks for 'the people'". Some scholars therefore suggest dialogic formats: translating the research into the community's language, asking their opinion and recording their responses. As the gap between researcher and researched narrows, the scholar's version is more likely to be questioned or corrected, which makes research more controversial and difficult, "but in the long run this can only be a good thing", making social science more democratic.

Surveys

The survey is "probably the best known sociological method", now so common in public life that it is used far beyond sociology: predicting election results, devising marketing strategies, eliciting opinions. A survey provides an overview, a comprehensive perspective on a subject based on information from "a carefully chosen representative set of people", the respondents. It is usually done by large teams: researchers who design the study and their investigators or research assistants. Questions may be asked orally in personal visits or by telephone, answered in writing through questionnaires delivered or posted, or, increasingly, electronically by email or web forms.

The survey's main advantage is that it lets us generalise to a large population while studying only a small part of it, with a manageable investment of time, effort and money. This "shortcut" depends on sampling theory, a branch of statistics, and its key element is the representativeness of the sample, resting on two principles:

1. Stratification: all relevant sub-groups of the population must be recognised and represented. India's population is divided into very different rural and urban sectors; a State's rural population lives in villages of different sizes; a village is stratified by class, caste, gender, age and religion. Which strata are relevant depends on the research objective: all religions for a study of attitudes to religion; workers, managers and industrialists for a study of attitudes to trade unions. NCERT notes that this is a statistical notion of stratification, different from the sociological concept (which this book teaches in chapter 2).
2. Randomisation: the actual unit chosen (person, village or household) must be selected purely by chance, which rests on probability, as when a fair coin has an exactly equal chance of heads or tails. Only then is the sample representative. A survey team that chooses only villages near the main highway, or mostly middle-class households, or households it knows, has drawn a purposive sample, not a random one. Randomness is ensured by drawing lots, rolling dice, random number tables, or random numbers generated by computers.

NCERT's worked example tests the hypothesis that smaller, more intimate communities have greater inter-community harmony than larger, impersonal ones, in the rural areas of one State: take the census list of villages with their populations; define "small" and "large" and drop the medium villages, giving a list stratified by size; give each stratum equal weight by numbering each list and drawing lots for 10 small and 10 large villages; then study the 20 villages. Real studies use more stages and strata, but the principle is the same: a small sample carefully selected to stand for the whole, whose results are generalised to the population.

Bigger samples are more likely to be representative, the extreme being the census, which covers the whole population; in practice sample sizes range from 30-40 to many thousands. But "it is not only the size of the sample that matters; its mode of selection is even more important". The survey's unique advantage is an aggregated picture, based on a collectivity rather than individuals taken separately: many social problems become visible only at this level. Its disadvantages are the other side of its breadth: no depth, little time per respondent, the difficulty of asking complicated questions identically through many investigators (so the questionnaire, or "survey instrument", must be designed with great care), no long-term relationship or trust, and in the end dependence on "a tightly structured inflexible questionnaire" and on the goodwill and co-operation of respondents.

The Census and the National Statistical Organisation

NCERT's box describes India's population census, taken every ten years, as "the largest such exercise in the world", involving lakhs of investigators, enormous logistics and expenditure, and including every household and every one of "more than one billion" people. Many developed countries no longer take a full census and rely on sample surveys, which have proved very accurate. In India the National Statistical Organisation (NSO) conducts sample surveys every year on family expenditure, employment and unemployment and other subjects, and every five years a bigger survey of about 1.2 lakh households and more than 6 lakh persons, which NCERT counts among the biggest regularly conducted surveys in the world. Since India's population exceeds a billion, that sample is "only about 0.06 per cent", yet because it is scientifically selected it can estimate the characteristics of the whole population.

Several statements in the box have dated. The table below sets the 2026 position beside NCERT's text.

Aggregate Statistics: The Child Sex Ratio

NCERT's box on the "alarming decline in the sex ratio" shows why some problems need a census or large survey. The child (juvenile) sex ratio, girls per 1,000 boys aged 0-6, has fallen over the decades for India and many States, worryingly in Punjab, Haryana, Delhi and Himachal Pradesh. This is an aggregate or macro variable: looking at individual families we cannot see the problem, since one family's proportion of boys and girls could be offset by another's; only by collating statistics for large populations can the ratio for the community be calculated and the problem identified.

NCERT's 2011 column is the provisional release of 2011 (its source line is a private website); the final Census figures are in the last column. The direction of NCERT's argument is unchanged: the national ratio fell from 945 to 927 to 919 over two decades.

The Interview

An interview is "a guided conversation between the researcher and the respondent". Its simplicity is deceptive: it takes practice and skill. It occupies the ground between a survey's structured questionnaire and the completely open-ended interaction of participant observation. Its chief advantage is extreme flexibility: questions can be rephrased, the order changed, productive subjects extended and touchy ones cut short or postponed, all during the interview. The same flexibility makes it vulnerable to the respondent's changes of mood or the interviewer's lapses of concentration: an "unstable and unpredictable format".

Styles differ. Some prefer a loose structure with a checklist of topics, others specific questions for every respondent. Recording ranges from audio or video, through notes taken during the interview, to writing up from memory afterwards: equipment can make a respondent uneasy and formal, while lighter methods can miss important information, and sometimes the physical or social circumstances decide. Write-ups also differ, from an edited, "cleaned up" continuous narrative to a transcript that keeps the asides and digressions. The interview is often used with other methods: long conversations with key informants in participant observation give a concentrated account that clarifies the rest, and intensive interviews add depth and detail to survey findings. As a method it depends on personal access and on the rapport and trust between respondent and researcher.

PART 3 — UPSC Integration

Reading a Statistic Like a Sociologist

Exam Strategy

For Prelims: know NCERT's terms precisely: methodology vs method; reflexivity; triangulation; participant observation; genealogy; informant; sample, population, stratification (statistical sense), randomisation, purposive sample, sampling error and non-sampling error; census. Match researchers to fields (Malinowski: Trobriand; Whyte: Street Corner Society; Srinivas: Rampura, The Remembered Village; Dube: Shamirpet, Indian Village; Wisers: Behind Mud Walls). Keep current facts dated: Census 2027 reference date 1 March 2027; caste enumeration (CCPA decision 30 April 2025); PLFS redesigned January 2025; NFHS-6 released 29 May 2026.

For Mains: NCERT's ten exercises cover why method matters in sociology, why objectivity is complicated, how sociologists strive for it, reflexivity, what fieldworkers do, the strengths and weaknesses of participant observation, the survey method and its weaknesses, criteria for a representative sample, and the interview. A strong answer pairs each method with its best-suited question and makes the case for triangulation.

Avoid: claiming that any one method is superior; treating a big sample as automatically representative; quoting provisional figures as final; repeating NCERT's dated census box as current.
