Manitoba Mincome — Guaranteed Annual Income
University of Manitoba / Canadian federal and Manitoba governments · Manitoba, Canada · 1974
Summary
The Manitoba Mincome experiment is remarkable for a result nobody saw coming: when researchers re-examined hospitalization records 30 years after the program ended, they found that guaranteed income recipients had substantially fewer hospitalizations — particularly for mental health conditions and accidents. The labor supply effect that critics predicted — mass withdrawal from work — did not materialize. The two groups that worked less were mothers who delayed returning to work after childbirth, and teenagers who chose to stay in school longer rather than drop out for economic reasons. Both are arguably improvements in human welfare rather than the 'welfare trap' critics feared. The study is limited by its quasi-experimental design and the incomplete data from the abrupt program cancellation. But its health findings remain the most striking evidence that income security may function as a public health intervention.
Research question
"Does a guaranteed annual income program improve health and social outcomes — and what happens to labor supply when the income floor is removed?"
Methodology
Intervention
Dauphin, Manitoba (population ~12,000) participated in a town-wide Mincome experiment: every family below a threshold income received a guaranteed top-up ensuring their income reached a minimum level. The program ran 1974–1979, then was cancelled by a new government. Evelyn Forget re-analyzed the data 30 years later using hospitalization records from Manitoba Health.
Assignment
Quasi-experimental; Dauphin was a town-wide saturation site; Forget (2011) used difference-in-differences comparing Dauphin to control towns and to periods before/after program; hospitalization records were the primary data source
Sample size
~1,000 Dauphin families enrolled; town-wide saturation site among 4 Manitoba sites
Primary outcome
Hospitalization rates; mental health-related hospitalizations; high school completion; labor supply
Effect estimate
Hospitalization rates fell 8.5% relative to control communities; mental health hospitalizations fell significantly; domestic violence-related hospitalizations fell; high school completion increased; labor supply: only small reductions, primarily among mothers (who delayed return to work after childbirth) and teenagers (who stayed in school longer)
Decision
Results only fully analyzed 30 years after program ended; Forget's 2011 paper reignited the guaranteed income debate in Canada; Manitoba results cited in Senator Art Eggleton's proposals for national basic income; results influenced the design of the 2017–2019 Ontario Basic Income Pilot (later cancelled mid-experiment by the Ford government, causing significant methodological damage to a running RCT)
Result
Positive
Hospitalization rates fell 8.5% relative to control communities; mental health hospitalizations fell significantly; domestic violence-related hospitalizations fell; high school completion increased; labor supply: only small reductions, primarily among mothers (who delayed return to work after childbirth) and teenagers (who stayed in school longer)
Evidence strength
Moderate
Quasi-experimental design; causal interpretation requires care.
