The evidence
What they say. What the numbers say.
Every justification offered for the Bill, next to the best data we could find. In every one of them the data points the other way.
“Citizenship is an important part of successful integration.”
Jim O’Callaghan, Minister for Justice11Agreed. The research says citizenship is what causes integration, and the earlier it comes the stronger the effect. Adding three years delays the thing the Minister says he wants.202118
“Bringing us more in line with other European Union member states.”
Micheál Martin, Taoiseach11The most common requirement in the world. Germany went from eight to five in 2024. The six countries the Minister compared us to are among the strictest in Europe.18192
“Economic self-sufficiency … an absence of reliance on social assistance.”
Department of Justice, 9 Sept 20261Non-EU-born residents at risk of poverty, against Irish-born. They work more, are paid less, and 37% spend over a third of their income on rent against 9% of Irish-born. A welfare bar hits exactly them.42
Not said, but implied by “the biggest reform in a generation”: the system needs fixing.
Jim O’Callaghan, Minister for Justice2In 2024 the Department cleared more cases than it received, and the wait for a decision fell from two years to about eight months.2628

The published research
Every study we could find says the opposite.
Citizenship is what makes people belong. It is not a prize for already belonging.
Swiss referendums narrowly won or lost, comparing near-identical applicants. Lasting gains in political integration.
PNAS, 201520
The earlier it comes, the more good it does.
Same design, social integration. Effects strongest for the most marginalised applicants, and stronger the earlier in the residence period naturalisation occurs.
American Political Science Review21
People earn more for the rest of their working lives.
Quasi-experimental evidence on marginalised immigrants in Switzerland.

“Restricting access to citizenship may delay rather than bolster migrants’ integration.”
The European Parliament’s own research service, reviewing the restrictive turn across the EU and finding it “at odds with important findings in citizenship research”.

general
Ireland is not the only country tightening. Finland, Cyprus, Sweden and Portugal have moved too. But Germany went the other way, five years is still the most common rule in the world, and the global average is seven.1819 When the Minister compared Ireland to other countries he picked Austria, Italy, Lithuania, Slovenia, Spain and Switzerland2: six of the strictest. Not Germany.
Every bar cites its own law. Hover the number beside a country for the statute and the article the figure comes from. Ordinary naturalisation only, facilitated routes excluded: that is why Portugal shows ten and not the seven years it asks of EU and Portuguese-speaking nationals64 and Spain shows ten and not the two years it asks of nationals of Ibero-American countries including Brazil.65 Residence periods are policy instruments, not neutral measures of belonging. Cross-check across all of them: EPRS 2025, drawing on GLOBALCIT and EMN.18
Longer waits did not mean fewer immigrants. They meant more people without rights.

These are the people Ireland asked to come
