Universal Basic Income: What 40 Years of Data Actually Tell Us

From Alaska to Finland, through Stockton and Kenya, six rigorously documented experiments contradict the myth of dependency. Recipients work more, invest more, and do better.

Universal Basic Income: What 40 Years of Data Actually Tell Us

TL;DR: In Stockton, California, 125 households received $500 per month for two years. Full-time employment rose from 28% to 40%. In Finland, recipients felt better and had more confidence in their future. In Kenya, “the common fear of laziness never materialised.” In Alaska, 40 years of annual dividends — zero employment collapse. The data exist. And they say something different from what you may have heard.

When economists debate universal basic income, the first objection almost always resurfaces. It takes a thousand forms, but it comes down to the same question: what if people stopped working?

It’s a legitimate concern. Unconditional money didn’t exist. So how could anyone know?

The answer now exists — not definitively, since no wealthy country has yet deployed a universal income at national scale. But six experiments, across three continents and four decades, provide rigorously measured data. And they systematically contradict the myth of dependency.

Stockton: The Safety Net Liberates, It Doesn’t Immobilise

In February 2019, the city of Stockton, California began paying $500 per month to 125 households for 24 months, with no conditions. Nobody checked how the money was spent. The experiment was monitored with a rigorous control group.

The results — published by Results for America in October 2021 — are precise: the full-time employment rate among recipients rose from 28% to 40%, a gain of 12 percentage points. In the control group, the increase was 5 points. Recipients found better jobs, not fewer jobs.

What did they spend the money on? Less than 1% on alcohol or tobacco. The rest: food, clothing, utilities, household goods. The ability to handle an unexpected expense rose from 25% to 52% within a year.

The safety net doesn’t slow the race. It allows people to wait until they’re running in the right direction.

Finland: Mental Health as an Employment Factor

Between January 2017 and December 2018, the Finnish government paid €560 per month to 2,000 unemployed benefit recipients, with no obligation to seek work. The aim: to measure the effect on employment and wellbeing.

The official report from the Finnish Ministry of Social Affairs (STM, May 2020) is honest about the employment effects: “small.” Recipients worked an average of 78 days — 6 days more than the control group over two years.

But the report highlights something essential: recipients were “more satisfied with their lives and experienced less psychological stress.” And it notes that for some unemployed people, the obstacles to employment “are not related to bureaucracy or financial incentives” — it’s primarily a problem of mental health and self-confidence. Confidence that basic income improves.

That’s not a footnote. It’s a mechanism.

Kenya: Entrepreneurship, Not Inactivity

The largest UBI study in the world is taking place in rural villages in Kenya. Since 2018, GiveDirectly has been following nearly 200 villages in Siaya and Bomet counties, with three payment formats: long-term (12 years), short-term (2 years), and lump sum.

The first results published in December 2023 are clear: “The common fear of ‘laziness’ never materialised. Recipients invested, became more entrepreneurial, and increased their incomes.”

An important nuance: the most dramatic income effect — +50% compared to the control group — was measured in the group receiving a lump sum, not the monthly income. All three formats produce positive effects on occupational choices, but their dynamics differ. The lump sum releases startup capital; the monthly income stabilises daily life. Both have their role.

Alaska: 40 Years of Natural Experiment

Since 1982, Alaska has paid an annual dividend to all its residents — with no income requirement, no employment obligation. In 2024, 624,489 Alaskans received a total of $1.06 billion. The per-person amount varies with oil revenues: from $1,000 (1982) to $3,284 (2022).

In 2022, economists Damon Jones and Ioana Marinescu published in the American Economic Journal the most rigorous analysis available: “the dividend had no effect on employment and increased part-time work by 1.8 percentage points (17%).” Part-time work increased — a sign of choice, not withdrawal.

Forty years of data. Zero employment collapse.

Wales: The Most Generous Programme in the World

Since July 2022, the Welsh government has been paying £1,600 gross per month (£1,280 net) for two years to young people leaving the care system. This programme, officially documented, is described in an evaluation published in PLOS ONE as “the most generous basic income scheme in the world.”

644 people participated. The uptake rate: 97%. The full quantitative evaluation — mental health, employment, housing compared to a control group — is expected in 2027. But one thing is already measured: when conditions are dignified, people participate.

Spain: Real Reach, Universality Still Ahead

In May 2020, Spain created the Ingreso Mínimo Vital (IMV), a guaranteed minimum income for households in economic vulnerability. One important clarification: the IMV is a means-tested income, not universal. It does not cover all Spanish residents, but those whose resources fall below a threshold.

By 2025, 2,441,647 people in 799,553 households were receiving it — including 68% women and 40.9% minors. The base amount: €733.60 per month for an individual, up to €1,613.92 for a household of five or more (2026 amounts, up +11.4%).

Documented limitation: according to AIReF (Spain’s independent fiscal authority), around 55% of eligible households had not enrolled. Administrative complexity remains a real barrier to access, even when the right exists.

The Limits the Data Honestly Pose

These six experiments are evidence, not blueprints. Some limits deserve to be stated clearly.

The Finnish employment effect was small. +6 days over two years — the ministry itself describes this as a “small” result. The experiment targeted unemployed benefit recipients, not the general population.

In Alaska, inequality is widening. An analysis summarised in Science News (2019) concludes that income inequality grew 21% faster in Alaska than it would have without the programme. Wealthier households invest more in their children’s education, widening the intergenerational gap.

In Wales, the impact evaluation awaits 2027. Current reports document implementation and young people’s testimonies. Impact figures are still to come.

Large-scale funding remains an open question. No wealthy country has yet deployed a universal income at national level. Extending it to all residents of a developed country is a fiscal policy choice — real, non-trivial, and unresolved.

What these data collectively show: basic income recipients do not disappear from the labour market. They position themselves differently — with more room to choose, to take care of their mental health, to take entrepreneurial risks. Alaska has been measuring this since 1982. Stockton confirmed it in 2021. Kenya in 2023.

The question is no longer whether it’s possible. The question is how — and who decides.
