IELTS vocabulary: Immigration

Immigration turns up as a Task 2 prompt more often than almost any other social topic, and it is also the topic where vague, repetitive vocabulary does the most damage — because the argument itself is already contested, an essay that just repeats "immigrants" and "immigration is good/bad for a country" eight times reads as both linguistically thin and analytically shallow. The specific failure mode here is different from a topic like the environment: candidates on immigration often know several relevant words but reach for only the most generic ones out of caution, worried that a more precise term might sound like it's taking a side. That caution is misplaced — precise vocabulary and a balanced argument are not in tension, and an examiner assessing Lexical Resource is looking for range and accuracy, not safety. This article works through the vocabulary in the order an essay actually needs it: the movement itself, integration, economic effects, policy, and then the pairs of terms that even confident candidates use interchangeably when they shouldn't.

Start with the vocabulary of movement, because candidates frequently blur terms that have distinct, examinable meanings. "Immigration" is the act of moving into a country to settle there, while "emigration" is leaving one's own country to settle elsewhere — the same person emigrates from their home country and immigrates to their destination, and mixing the two up is a genuine accuracy error, not just a stylistic one. "Migrant" is the broad, neutral umbrella term for anyone moving between countries, regardless of reason. "Economic migrant" narrows this to someone moving primarily for work or a better standard of living, while "refugee" describes someone who has fled their country because of war, persecution, or disaster and cannot safely return. "Asylum seeker" is narrower still: someone who has formally requested protection in another country and is awaiting a decision on that claim — not yet legally a refugee, though often discussed as if the terms were synonyms. "Undocumented immigration" (sometimes called "irregular migration") refers to entering or remaining in a country without legal authorisation, a more neutral and accurate phrase than "illegal immigrants," which many style guides and international organisations now avoid because it labels a person, not an act.

Integration vocabulary is where essays either show genuine social understanding or default to cliché. "Cultural integration" describes newcomers and the host society adapting to live alongside one another, typically understood as a two-way process. "Assimilation" is a stronger, more one-directional term: newcomers largely adopting the language, customs, and norms of the host culture, sometimes at the expense of their own — a term some sociologists treat as more contested than "integration" precisely because of that one-way implication. "Multiculturalism" describes a society, or a policy stance, that actively supports multiple distinct cultures coexisting rather than expecting convergence toward one dominant culture. Two competing metaphors are worth knowing for a genuinely sophisticated Task 2 paragraph: the "melting pot" model, where different cultures are expected to blend into a single new national identity, versus the "salad bowl" (or "mosaic") model, where distinct cultural identities remain visible and are held to coexist rather than merge. "Host community" is the standard neutral term for the population already living in the receiving country, useful whenever an essay needs to discuss the receiving side of integration rather than only the migrants themselves.
