Does immigration lower wages? What the evidence actually says
The belief that immigration broadly suppresses wages and destroys jobs for existing workers rests on the assumption that an economy contains a fixed number of jobs, and that assumption is false. Decades of research across multiple countries find immigration has small effects on average wages, with t
Immigration and wages is one of the few areas where the empirical evidence and the popular intuition point in noticeably different directions, and it's worth covering honestly precisely because it complicates a common assumption rather than confirming it.
The fallacy underneath the intuition
The intuitive case against immigration assumes a fixed number of jobs exist in the economy, immigrants take some of them, and therefore fewer remain for everyone else. The error is treating the number of jobs as static. Immigrants are not only workers, they are also consumers, entrepreneurs and taxpayers, and they increase both the supply of labour and the demand for it simultaneously. An immigrant who works also spends, on rent, food, services and transport, generating demand that supports additional employment elsewhere in the economy. An immigrant who starts a business creates jobs directly. An immigrant who fills a skill shortage allows an existing firm to expand, creating downstream employment that wouldn't otherwise exist. The fallacy treats the economy as a fixed pie to be divided rather than a dynamic system that grows with population and demand.
What a large body of evidence actually finds
A comprehensive meta-analysis covering 45 primary studies published between 1982 and 2007, spanning 1,572 effect sizes, found that the labour market impact of immigration on wages and employment is rather small on average, varying by skill level and local conditions but showing no consistent evidence of large-scale wage suppression at the aggregate level. The UK's Migration Observatory at Oxford found negative effects concentrated on low-paid workers and positive effects on high-paid workers, but both effects were small, with the negative effect on low-paid workers real but modest and concentrated in sectors with high immigrant representation. The US National Academies of Sciences ran the most thorough modern review of American immigration economics in 2016 and found first-generation immigrants impose a modest net fiscal cost through service use, while second-generation immigrants are among the strongest fiscal contributors of any group, stronger even than children of native-born citizens, and that immigration has little to no negative long-run effect on the overall wages and employment of native-born workers.
Where the negative effects are real
The evidence does not say immigration harms no one, and treating it as though it does would be its own kind of dishonesty. Low-skilled native workers in direct occupational competition with low-skilled immigrants experience genuine wage pressure. Prior immigrants are the group most affected by new immigration from the same country of origin, since they compete most directly for similar roles. Local labour markets hit by sudden, large immigration shocks can experience real short-run disruption before the broader economy adjusts. The UK finding on low-paid workers is the most credible evidence of a real, if modest, negative wage effect anywhere in the literature. This is an important distinction: the claim is not that immigration harms no one, it is that aggregate harm is small and specific harm is concentrated, which is a genuinely different policy question than whether immigration lowers wages in general.
The housing argument is more honest than the wages argument
Australia's Net Overseas Migration exceeded 400,000 in 2022 to 2023, generating real political reaction over housing and infrastructure pressure, and this is worth separating clearly from the wages debate. The most credible case against high immigration levels in Australia right now is not that it suppresses wages, the evidence for that is thin at the aggregate level, it is that a building sector unable to keep pace with population growth produces genuine cost-of-living harm through housing supply. This is a more defensible version of the anti-immigration economic argument than the wages claim, and conflating the two weakens an argument that has real merit on its own terms.
Why this matters for how the debate gets framed
Anti-immigration sentiment is often framed as protecting workers broadly, but the group it actually protects is narrower: incumbent workers already employed in sectors facing new competition. The workers who benefit from immigration, employers who can hire, consumers of lower-cost services, businesses that expand because of population growth, are diffuse and politically far less audible than the concentrated, organised interests who feel the competition directly. Immigration restrictions intended to protect wages can also reduce economic dynamism, worsen skill shortages and slow the demographic replacement of an ageing workforce, costs Australia's aged care, healthcare and construction sectors are already living with.
Frequently asked questions
Does immigration lower wages for everyone?
No. The evidence finds small effects on average wages overall, with real but modest negative effects concentrated specifically on low-skilled workers in direct competition with new immigrants, not the workforce broadly.
If wage effects are small, why does immigration feel like it's driving up living costs?
Housing is the more credible channel. Rapid population growth outpacing housing supply produces genuine cost-of-living pressure that is separate from, and better evidenced than, any aggregate wage effect.
Who benefits most from immigration?
Employers able to fill skill shortages, businesses that expand because of population-driven demand, consumers of services that become more available, and, over the long run, the fiscal position of the country, since second-generation immigrants are strong net fiscal contributors.
Is there a group where the negative wage evidence is strongest?
Yes, prior immigrants from the same country of origin as new arrivals, since they tend to compete most directly for similar work, along with low-skilled native workers in the same occupations.
