Australia, Canada and the UK are among the world's leading immigration destinations, but all three are facing similar questions about how migration affects population growth, housing, infrastructure, labour markets and public confidence.
While their systems and measurements differ, recent policy changes show a common trend: governments are attempting to reduce or better manage migration while protecting access to workers and skills that support economic growth.
NOM rose sharply after the pandemic, moving from approximately -94,000 in March 2021 to 555,812 in September 2023. It later fell to around 301,000, but migration remains a major policy issue.
The Australian government is seeking to reduce NOM further, with a target of 245,000 by 2027. Other political voices have called for deeper reductions.
Much of the debate centres on housing affordability and infrastructure. Supporters of tighter migration argue that high population growth adds pressure to already constrained housing and public services, although the extent of migration's contribution remains contested.
The more difficult question is where reductions should occur.
Different migration categories affect employers, students, universities and labour markets in different ways. Reducing migration may therefore address population growth concerns while also creating shortages in industries that depend on international workers.
There has also been discussion about linking NOM to overall population size, including a target equivalent to around 1% of the population. However, this has not become formal Australian government policy.
Canada's Immigration Levels Plan sets annual targets for permanent residents while also increasingly addressing temporary residents.
The change followed growing concerns about housing, infrastructure and the scale of temporary resident programmes. Under the 2026 to 2028 Immigration Levels Plan, permanent resident admissions are expected to stabilize at 380,000 annually.
Temporary resident arrivals are projected at 385,000 in 2026 and 370,000 in both 2027 and 2028.
Canada is also aiming to keep permanent resident admissions below 1% of the population and reduce the temporary resident population to below 5% of the total population by the end of 2027.
At the same time, Canada continues to emphasize economic immigration. Economic programmes are expected to account for approximately 63% of permanent resident admissions in 2026 and 64% in 2027 and 2028.
The policy therefore combines tighter control of temporary migration with continued emphasis on immigrants who can support labour shortages, regional economies and long-term growth.
As of July 1, 2026, Canada's estimated population was 41,798,407, representing a 0.35% increase compared with the second quarter of 2025. This was considerably below the 0.88% growth recorded over the comparable previous period.
The estimated non-permanent resident population was approximately 2.78 million in the second quarter of 2026, down 0.7% from the previous quarter.
Canada also admitted 99,148 permanent residents in the second quarter of 2026. Although this was higher than the previous quarter, it was approximately 4% lower than the same quarter of 2025.
These figures are broadly consistent with the government's lower migration targets, although the full impact of the revised policy will take longer to assess.
The headline figure combines people with very different reasons for moving, including workers, students, temporary migrants and humanitarian entrants.
The UK has previously used explicit numerical ambitions. Former Prime Minister David Cameron pledged before taking office to reduce net migration to the "tens of thousands". That objective proved difficult to achieve.
More recently, governments have pursued lower migration without setting a fixed numerical cap.
Net migration reached a revised 906,000 in the year ending June 2023, creating substantial pressure for policy action.
The UK subsequently tightened several areas of its immigration system, including salary thresholds, sponsorship requirements, dependant rules and particular migration routes.
These measures contributed to net migration falling to a provisional 171,000 in the year ending December 2025.
However, government policy was not the only factor. International students from large post-pandemic cohorts have increasingly completed their studies and left the UK, also contributing to the reduction.
Migration affects population size, workforce growth, labour shortages and public finances. Some routes can be restricted relatively quickly, but the workers affected may still be needed by employers.
The Migration Advisory Committee estimates that Skilled Worker main applicants outside the Health and Care route generate an average lifetime net fiscal contribution of approximately £689,000 per person.
The Institute for Fiscal Studies has also estimated that lower migration projections could reduce government fiscal headroom by around £1 billion to £4 billion, partly because slower labour-force growth can weaken future economic and tax revenue growth.
This creates an important policy trade-off. Lower migration may respond to concerns about population growth, but excessive restrictions can also reduce access to workers who contribute significantly to productivity and public finances.
The UK has therefore increasingly combined broader restrictions with targeted measures designed to support strategically valuable migration.
A reduction in total migration does not automatically mean that the system has become more economically effective. Equally, a higher migration figure does not necessarily indicate poor policy.
Governments need to consider:
Who is arriving?
Why are they coming?
How long will they stay?
What contribution do they make?
Which migration flows can government realistically control?
These questions matter because governments have greater influence over some migration categories than others. Eligibility requirements, salary thresholds, sponsorship rules and dependant policies can significantly affect regular migration, while emigration and some humanitarian movements are much harder to control precisely.
Canada and the UK also show that reducing migration can involve significant trade-offs. Lower inflows may ease population pressures while simultaneously creating labour shortages or reducing workforce growth.
For Australia, this is particularly relevant as the government considers how further reductions in NOM should be achieved.
A sustainable system must balance housing and infrastructure pressures with the need for workers, skills, students, investment and economic growth.
Australia, Canada and the UK are taking different approaches, but their recent experiences point to the same broader lesson: policymakers need to look beyond headline migration numbers and consider the composition, purpose and economic contribution of migration.
Reducing migration may be achievable through a combination of policy measures. The greater challenge is ensuring that those reductions do not undermine the workforce and economic capacity that immigration is also intended to support.
While their systems and measurements differ, recent policy changes show a common trend: governments are attempting to reduce or better manage migration while protecting access to workers and skills that support economic growth.
Australia: Reducing Net Overseas Migration
Australia measures migration through Net Overseas Migration (NOM). This broadly counts people who enter and remain in Australia for at least 12 months over a 16-month period, minus people who leave for a comparable period.NOM rose sharply after the pandemic, moving from approximately -94,000 in March 2021 to 555,812 in September 2023. It later fell to around 301,000, but migration remains a major policy issue.
The Australian government is seeking to reduce NOM further, with a target of 245,000 by 2027. Other political voices have called for deeper reductions.
Much of the debate centres on housing affordability and infrastructure. Supporters of tighter migration argue that high population growth adds pressure to already constrained housing and public services, although the extent of migration's contribution remains contested.
The more difficult question is where reductions should occur.
Different migration categories affect employers, students, universities and labour markets in different ways. Reducing migration may therefore address population growth concerns while also creating shortages in industries that depend on international workers.
There has also been discussion about linking NOM to overall population size, including a target equivalent to around 1% of the population. However, this has not become formal Australian government policy.
Canada: Reducing Temporary Migration
Canada's approach differs from Australia and the UK because it separately plans permanent and temporary migration.Canada's Immigration Levels Plan sets annual targets for permanent residents while also increasingly addressing temporary residents.
The change followed growing concerns about housing, infrastructure and the scale of temporary resident programmes. Under the 2026 to 2028 Immigration Levels Plan, permanent resident admissions are expected to stabilize at 380,000 annually.
Temporary resident arrivals are projected at 385,000 in 2026 and 370,000 in both 2027 and 2028.
Canada is also aiming to keep permanent resident admissions below 1% of the population and reduce the temporary resident population to below 5% of the total population by the end of 2027.
At the same time, Canada continues to emphasize economic immigration. Economic programmes are expected to account for approximately 63% of permanent resident admissions in 2026 and 64% in 2027 and 2028.
The policy therefore combines tighter control of temporary migration with continued emphasis on immigrants who can support labour shortages, regional economies and long-term growth.
Early Signs of Canada's New Direction
Recent population data indicate slower growth.As of July 1, 2026, Canada's estimated population was 41,798,407, representing a 0.35% increase compared with the second quarter of 2025. This was considerably below the 0.88% growth recorded over the comparable previous period.
The estimated non-permanent resident population was approximately 2.78 million in the second quarter of 2026, down 0.7% from the previous quarter.
Canada also admitted 99,148 permanent residents in the second quarter of 2026. Although this was higher than the previous quarter, it was approximately 4% lower than the same quarter of 2025.
These figures are broadly consistent with the government's lower migration targets, although the full impact of the revised policy will take longer to assess.
UK: Using Policy Levers to Reduce Net Migration
The UK defines net migration as the difference between people immigrating and emigrating for 12 months or more.The headline figure combines people with very different reasons for moving, including workers, students, temporary migrants and humanitarian entrants.
The UK has previously used explicit numerical ambitions. Former Prime Minister David Cameron pledged before taking office to reduce net migration to the "tens of thousands". That objective proved difficult to achieve.
More recently, governments have pursued lower migration without setting a fixed numerical cap.
Net migration reached a revised 906,000 in the year ending June 2023, creating substantial pressure for policy action.
The UK subsequently tightened several areas of its immigration system, including salary thresholds, sponsorship requirements, dependant rules and particular migration routes.
These measures contributed to net migration falling to a provisional 171,000 in the year ending December 2025.
However, government policy was not the only factor. International students from large post-pandemic cohorts have increasingly completed their studies and left the UK, also contributing to the reduction.
The Economic Trade-Off
The UK's experience demonstrates that reducing migration can have economic consequences.Migration affects population size, workforce growth, labour shortages and public finances. Some routes can be restricted relatively quickly, but the workers affected may still be needed by employers.
The Migration Advisory Committee estimates that Skilled Worker main applicants outside the Health and Care route generate an average lifetime net fiscal contribution of approximately £689,000 per person.
The Institute for Fiscal Studies has also estimated that lower migration projections could reduce government fiscal headroom by around £1 billion to £4 billion, partly because slower labour-force growth can weaken future economic and tax revenue growth.
This creates an important policy trade-off. Lower migration may respond to concerns about population growth, but excessive restrictions can also reduce access to workers who contribute significantly to productivity and public finances.
The UK has therefore increasingly combined broader restrictions with targeted measures designed to support strategically valuable migration.
Lessons Across Australia, Canada and the UK
The experiences of these three countries suggest that net migration is an important indicator, but it is not a complete measure of whether an immigration system is working effectively.A reduction in total migration does not automatically mean that the system has become more economically effective. Equally, a higher migration figure does not necessarily indicate poor policy.
Governments need to consider:
Who is arriving?
Why are they coming?
How long will they stay?
What contribution do they make?
Which migration flows can government realistically control?
These questions matter because governments have greater influence over some migration categories than others. Eligibility requirements, salary thresholds, sponsorship rules and dependant policies can significantly affect regular migration, while emigration and some humanitarian movements are much harder to control precisely.
Canada and the UK also show that reducing migration can involve significant trade-offs. Lower inflows may ease population pressures while simultaneously creating labour shortages or reducing workforce growth.
For Australia, this is particularly relevant as the government considers how further reductions in NOM should be achieved.
The Bigger Policy Question
The debate is increasingly shifting from how much migration a country should have to what type of migration it needs.A sustainable system must balance housing and infrastructure pressures with the need for workers, skills, students, investment and economic growth.
Australia, Canada and the UK are taking different approaches, but their recent experiences point to the same broader lesson: policymakers need to look beyond headline migration numbers and consider the composition, purpose and economic contribution of migration.
Reducing migration may be achievable through a combination of policy measures. The greater challenge is ensuring that those reductions do not undermine the workforce and economic capacity that immigration is also intended to support.
