Gini Coefficient (after tax)

Canada vs US Gini coefficient: a real gap, but mostly because the top of the US distribution is in another country

The OECD's after-tax disposable income Gini puts Canada around 0.30 and the United States around 0.39–0.40. On the World Bank/Census methodology the gap looks even larger — Canada's after-tax Gini was 0.300 in 2023 per Statistics Canada, while the US Census Bureau household money-income Gini was 0.481 in 2024. Whichever lens you use, the income gap is real and persistent: roughly 9 to 18 Gini points, depending on the methodology, and it has held since at least the late 1990s. But the most interesting recent finding from the Bank of Canada's own research is that Canada's lower number may partly be a survivorship statistic — the high earners who would have widened the top of Canada's distribution moved to the United States. This page is about that gap and the politics that surround it.

The numbers

From the OECD-style series shown above and the latest official agency releases:

• Canada, 2000: about 33.4 on the OECD index (equivalent to Gini ≈ 0.33).
• Canada, 2006 peak: about 34.1.
• Canada, 2020 trough: about 29.9 — the largest single-year decline in series history, driven by CERB.
• Canada, 2021: about 31.1.
• Canada after-tax Gini, 2023 (StatCan): 0.300.
• United States, 2000: about 40.1.
• United States, 2019 peak: about 41.9.
• United States, 2023: about 41.8.
• US household money-income Gini, 2024 (Census): 0.481.

A consistent feature across both methodologies: the US peak is higher, the US average is higher, and the gap has held within a 7–10 point band for the entire 25-year window. The 2020 dip in both countries is real, large, and was almost entirely undone within two years.

The 2020 pandemic compression

This is the most rhetorically powerful single fact in the series. Statistics Canada's after-tax Gini fell from 0.342 in 2015 to 0.302 in 2020 — the largest five-year decline since the series began in 1976. The 2020 single-year drop alone was enormous: counterfactually, Statistics Canada estimates Canada's Gini would have been 0.325 in 2020 without CERB, versus the 0.301 that was actually realized. CERB, the CRB, and the suite of business-support programs collectively compressed the income distribution by roughly 24 Gini points — the equivalent of erasing more than two decades of accumulated inequality in six months.

The American story is more complicated because of methodology. The headline Census money-income Gini increased 1.2% from 2020 to 2021 because pretax cash transfers don't show up in money income. But the supplemental poverty measure tells the opposite story: SPM child poverty fell from 9.7% in 2020 to 5.2% in 2021 — a 46% decline in one year, and a historic low. The expansion of the Child Tax Credit alone lifted 2.1 million children out of poverty. Both countries demonstrated something important: direct cash transfers compress the income distribution dramatically and quickly. Both countries then let the compression expire, and both Ginis snapped back. Canada's after-tax Gini bounced from 0.281 in 2020 to 0.288 in 2021 to 0.300 in 2022 and 0.300 in 2023. US SPM child poverty rebounded sharply through 2023 and 2024.

The MacGee–Rodrigue brain-drain twist

The single most original recent contribution to the Canada–US inequality literature is Bank of Canada Staff Working Paper 2024-49, "The Distributional Origins of the Canada–US GDP and Labour Productivity Gaps," by Jim MacGee (Bank of Canada) and Joel Rodrigue (Vanderbilt), released December 2024. The headline finding is striking: the top 10% of the income distribution accounts for roughly three-quarters of the Canada–US GDP per adult gap, and up to two-thirds of the measured labour productivity gap. Small differences at lower percentiles add up to almost nothing; the gap is concentrated at the top, especially among business owners and the university-educated.

The mechanism MacGee and Rodrigue lean on is selective brain-drain emigration. Canadian net emigration hit 65,372 in 2024–25, the highest reading in the 50-year series; roughly 70% of emigrants had university degrees versus 33% of the working-age population. The median wage offer for Canadians moving to permanent positions in the US was approximately USD $137,000 in 2024. The implication is uncomfortable: Canada's lower Gini may partly be a measurement artifact created by the fact that the high earners who would have widened the top of the Canadian distribution literally crossed the border and now show up in the US distribution instead. The two countries' inequality numbers are not independent observations.

The tax-and-transfer system

Canada and the United States both do relatively little income redistribution by OECD standards, but the starting point is what differs. Canada's market Gini is around 0.43 and the disposable Gini around 0.30 — roughly 13 Gini points of redistribution. The US market Gini is around 0.51 and the disposable Gini around 0.39 — roughly 12 points. The amount of redistribution is similar. The reason the post-redistribution gap is real is that Canadian market income is more equal in the first place, partly because of stronger labour-market institutions, partly because of the smaller top tail (see brain drain above), and partly because of healthcare cost burdens that are excluded from money-income measures.

Two tax-and-transfer institutions stand out:

1. Canada Child Benefit vs Child Tax Credit: the CCB pays up to $7,787/year per child under 6 (2025), is tax-free, income-tested, has no work requirement and no phase-in. A non-earner family receives the full amount. The US Child Tax Credit pays $2,000/child, is partially refundable (capped at $1,700 of refundable Additional CTC for 2024), and requires earned income of at least $2,500 to begin phasing in. The Center on Budget and Policy Priorities estimates a Canadian-style child benefit would cut US child poverty by more than half. A two-kid Canadian family at $100,000 of income receives roughly $10,000 more annually under CCB than the equivalent US family receives under CTC.
2. Healthcare cost burden: the US imposes about $3,372/capita in private out-of-pocket plus private insurance costs versus about $917/capita in Canada. Excluding the top 5%, non-elderly Americans face roughly 3–4x the risk of large medical bills compared to non-elderly Canadians. None of this shows up in money-income Gini measures, which is why disposable income Gini comparisons systematically overstate American well-being relative to Canadian.

The wealth picture is much less Canadian-favourable

The income Gini gap is roughly 9 to 18 points wide. The wealth Gini gap is much narrower. Both countries run wealth Ginis in the 0.83–0.86 range. The PBO's 2025 update found Canada's top 1% of families held 24% of net wealth in 2023; the top 10% held 53%. Canada's top 1% wealth threshold sits at about $7.4 million, against the US Federal Reserve's Survey of Consumer Finances 2022 figure of $13.6 million for the US top 1%. US median net worth jumped from $141,000 (2019) to $192,900 (2022) — the largest three-year jump on record — versus Canada's median family net worth of $519,700 in 2023 (the higher Canadian median is a housing-wealth artifact and partly reflects the Canada–US house price gap).

The narrative implication is awkward for Canadian progressives: Canada's much lower income inequality coexists with wealth inequality that is roughly comparable to the US, and with a top-tail wealth concentration in housing that has no obvious analogue south of the border. Canadian household balance sheets are more exposed to a single illiquid asset class than American ones are.

The Carney book vs Carney budget tension

Mark Carney spent a decade publicly worrying about inequality. In Value(s): Building a Better World for All (2021), he argued that market economies have evolved into "market societies" and cited OECD/IMF research that "relative equality is good for growth" and "more equal societies are more resilient." His May 2014 Bank of England speech "Inclusive Capitalism: Creating a Sense of the Systemic" — delivered to an audience that included Bill Clinton, Christine Lagarde, and Larry Summers — contained the famous line that "unchecked market fundamentalism can devour the social capital essential for the long-term dynamism of capital itself."

His first major act as Prime Minister, on March 21, 2025, was to cancel the proposed Capital Gains Inclusion Rate increase from 50% to 66.67% that Trudeau and Freeland had announced in Budget 2024. The hike would have hit roughly 40,000 individuals plus all corporations, making it the most progressive single tax measure on the table. Budget 2025 (tabled November 4, 2025 by Finance Minister François-Philippe Champagne) committed $280 billion in capital spending, ran a $78.3 billion deficit, raised defence, cut the public service, and offered a modest middle-class bracket reduction. There were no new measures explicitly framed around inequality reduction. The CCPA reads it as "fiscally conservative."

That tension — between a decade of inclusive-growth rhetoric and a first budget that rolled back the most progressive tax measure on offer — is the central political-economy story of Canadian inequality in 2025. It sits alongside David Macdonald's January 2026 CCPA report "Living the High Life," which found that the top 100 Canadian CEOs averaged $16.2 million in 2024, 248 times the average worker's $65,548, with CEO pay up 49% since 2020 versus 15% for workers.

The OBBBA shock on the US side

While Carney was cancelling Canada's capital gains hike, the US Congress was passing the One Big Beautiful Bill Act (OBBBA) in July 2025 — a permanent extension of the 2017 TCJA individual rate cuts plus significant cuts to SNAP and Medicaid eligibility. Yale Budget Lab's combined OBBBA-plus-tariffs distributional analysis found the bottom 80% of households see resource declines on average, with the middle quintile down roughly $1,300 (-1.2%) by 2027 and the top 1% up about $5,000. The US tariff package on its own is sharply regressive — the burden on the second income decile is 2.5x the burden on the top decile (-4.0% versus -1.6% of income).

Layered on top: the Trump administration has clawed back roughly $41.8 billion of the original $79.4 billion of IRS modernization funding from the Inflation Reduction Act. Enforcement budget is down to about $3.8 billion; staff is already down 31% from probationary terminations. ITEP and the Tax Law Center have called the cuts "open season for high-end tax evasion." The combined effect of OBBBA, tariffs, and IRS dismantlement is the largest single regressive shift in US fiscal policy since at least the early 1980s.

What to watch in 2026

1. Statistics Canada — Canadian Income Survey 2024 (Spring 2026). First post-CGIR-cancellation snapshot. Will show whether 2023's 0.300 Gini holds.
2. PBO — High-net-worth Families Database late 2026 update. Watch the top 1% wealth share — last reading 24% in 2023.
3. US Census ACS 2025 in September 2026. First full-year picture under the OBBBA + tariff regime, though SNAP cuts won't yet be active.
4. Federal Reserve SCF 2025 (late 2026 / early 2027). First triennial wealth update since 2022. Watch top 1% wealth share.
5. CCPA Highest-Paid CEOs 2025 report (January 2027). David Macdonald has flagged 2025 as likely to set new records.
6. Brain-drain emigration data. Watch whether 2024–25's record net emigration of 65,372 is the start of a trend or a one-off.

The stakes

Income inequality determines real living standards across the distribution, the political feasibility of progressive taxation, intergenerational mobility, and social cohesion. Canada's lower headline Gini is real but more fragile than it looks: it reflects a lower starting market income gap, a stronger family-benefit system, and a structural advantage from healthcare costs that don't appear in money-income statistics — but it also partly reflects selective emigration of the highest earners to the United States. As MacGee and Rodrigue have shown, the same structural advantages that give Canada a lower Gini also explain why Canada's GDP per capita gap and labour productivity gap with the US are concentrated almost entirely at the top of the income distribution.

The short version: Canada has lower income inequality than the US by roughly 9 to 18 Gini points depending on methodology, the gap is held up partly by stronger family transfers and partly by the implicit transfer of socialized healthcare, but it is also held up partly by the brain drain of the very high earners who would otherwise sit at the top of the Canadian distribution. The Carney government has so far chosen growth-and-investment framing over redistribution framing, and the most progressive tax measure on the table was cancelled in his first week. Whether that bet pays off depends on the productivity story, not the Gini story.
