Immigration policy openness — work visas, family reunification, asylum processing, border enforcement posture.
Security of private property rights — formal recognition, expropriation risk, titling systems.
The May 2018 Parallelsamfundsaftalen ("Et Danmark uden parallelsamfund") and the subsequent legislative package created a statutory ghettoliste (classification of residential areas exceeding thresholds on 'non- Western' residents, unemployment, education, income, and crime), imposed mandatory daycare from age one for children in those areas, established doubled-sentencing zones ('skærpet straf'-zoner), and required dispersed-housing targets — including demolition and reallocation of public-housing units. Enacted under the Løkke Rasmussen VLAK government; in 2021 the Frederiksen government renamed the categories from 'ghetto' to 'parallelsamfund' / 'omdannelsesområder' without softening the substantive requirements.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
