Countries set a wage floor in one of two ways. Most legislate a statutory national minimum. A group including Denmark, Sweden, Finland, Norway, Italy and Austria has no statutory minimum and sets floors through sector-wide collective agreements instead, which cover the large majority of workers. Comparing headline figures between the two systems tells you very little.
The two models
Statutory. A single national figure set by government, sometimes with regional or age variations. Easy to compare across borders, which is why it dominates published rankings.
Bargained. No national figure. Floors are set sector by sector in agreements between unions and employer federations, and coverage rather than the number is what matters. Where coverage is high, effective floors are frequently well above statutory minimums elsewhere.
A table of national minimum wages simply shows a blank for the second group, which reads as an absence of protection and is not one.
What actually varies
How it is uprated. Some index to inflation or median earnings automatically; others require a political decision each time, which is why the US figure has not moved since 2009.
Age and youth rates. Common in Europe, with lower rates for workers under a threshold age that step up over several years.
What counts toward it. Whether bonuses, in-kind benefits or tips can be counted varies widely and changes the real floor more than the headline number does.
The EU direction
The European Union adopted a directive on adequate minimum wages aimed at both models — promoting adequacy where a statutory minimum exists, and promoting collective bargaining coverage where it does not. It does not require any country to introduce a statutory minimum.
Comparing honestly
Convert to a common currency, adjust for price levels, and then check what the floor includes and how many workers it actually covers. A statutory figure that excludes large parts of the workforce is weaker than a bargained floor covering nearly everyone.
Common questions
Do all countries have a minimum wage?
No. Denmark, Sweden, Finland, Norway, Italy and Austria among others have no statutory minimum and set floors through sector-wide collective agreements.
Does that leave workers unprotected?
Not where bargaining coverage is high. Effective sectoral floors in those countries are frequently above statutory minimums elsewhere.
Why has the US rate not moved since 2009?
Because it requires a political decision each time rather than being indexed. Countries that index to inflation or median earnings move automatically.
Are youth rates common?
More so in Europe than in the US, with lower rates below a threshold age that step up over several years.
How should I compare two countries?
Convert, adjust for price levels, then check what counts toward the floor and how much of the workforce it covers.
