We observe large differences in cumulative naturalisation rates:
🇸🇪 80%
🇳🇱 67%
🇩🇰 37%
Differences increase after contrasting policy changes.
/3
Language requirements and integration tests were introduced in both Denmark (B1/B2) and the Netherlands (A2), but not in Sweden.
Dual citizenship was restricted in the Netherlands but liberalised in Sweden.
/4
We employ stratified Cox proportional hazard models to model duration until naturalisation.
We find that the introduction of citizenship tests is associated with substantial naturalisation gaps in both 🇩🇰 and 🇳🇱, esp. among migrants with lower educational background.
/5
Our findings on selection effects of civic 'integration' requirements are in line with previous work by @kkrjensen et al on 🇩🇰
Our estimates suggest that the introduction of civic integration requirements is associated with substantial delays in naturalisation.
Even in 🇳🇱 with modest A2 language requirement, esp. among lower educated migrants.
/7
When looking at #dualcitizenship, liberalisation increases the propensity to naturalise, but relevance is strongly conditioned by migrants’ origin context.
Higher rates if dual citizenship possible, esp. among 🇪🇺 migrants and those from highly developed origin countries.
/8
We find that being able to retain one’s origin citizenship is associated with durably higher naturalisation rates among EU citizens 🇪🇺 and migrants from highly developed countries.
/9
These results on delaying (civic integration requirement) and putting off naturalisation (dual citizenship restriction) are in line with earlier work on 🇳🇱 with @LabussiereMarie.
I had a look at party positions on #citizenship in 13 election manifestoes.
What did I find…?
1. Right-wing restriction 2. Left-wing silence / ambiguity 3. Small liberal center 4. New diaspora capture
A thread /
#1. Right-wing restriction
No surprise. Parties on center-right (VVD), orthodox Christian right (SGP) & populist right (FvD, PVV) advocate citizenship stripping.
‘Freedom’ Party PVV advocates restrictions of #dualcitizens (eg military)
FvD & SGP against pathway to citizenship.
#2. Left-wing silence / ambiguity I
The Greens (GL) & orthodox Socialist Party (SP) are silent on citizenship.
Labour Party (PvdA) somewhat ambiguous on #dualcitizenship: ‘no sign of lack of loyalty, but want to help people get rid of other citizenship, if they want’.
Difference-in-differences design exploits exogenous variation in origin country #citizenship legislation to identify the treatment effect of destination country policy reform.
