What the policy did

Amendments to Udlaendingeloven requiring both spouses to be at least 24 years old for family reunification, plus an 'attachment requirement' that the couple's combined ties be stronger to Denmark than to any other country. Also introduced a 7-year permanent-residence threshold and benefit restrictions (starthjaelp) for new arrivals.

Policy-content fingerprint — what this policy moved, on which axes

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.

intended
immigration openness
regulatory.immigration_openness
Immigration policy openness — work visas, family reunification, asylum processing, border enforcement posture.
decreased · strong
more restrictive (lower caps, tighter enforcement)
24-year rule and attachment requirement materially reduced non-EU family reunification.
transfer expansion
fiscal.transfer_expansion
Size of cash and near-cash transfer programmes (unemployment benefits, means-tested assistance, universal child benefits). Architecturally distinct from forced-saving schemes — see condition welfare_architecture.
decreased · weak
smaller transfer footprint
Starthjaelp benefit-floor reduction for new arrivals.

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?".

The net fiscal contribution of immigrants (taxes paid minus public services + transfers received, measured in lifetime NPV terms) varies systematically by (a) origin-country institutional quality, (b) skill level at arrival, (c) age at arrival, (d) duration of residence, and (e) legal status (working-age visa / family reunification / asylum).

UK post-1945 Attlee reforms (NHS, nationalisation of coal/rail/steel, expanded public housing) delivered measurable improvements in life expectancy and child mortality without undermining subsequent 1950s-1960s growth.

Italy's Reddito di Cittadinanza (RdC, March 2019) reduced absolute-poverty headcount among low-income Italian households by at least 15% within three years (2019-2022) but produced no measurable improvement in employment-rate among working-age beneficiaries, identified off the synthetic-control gap with EU peers (ESP, GRC, PRT) lacking comparable means-tested guaranteed-minimum-income programmes pre-2020.

The American Rescue Plan Act (March 2021) expansion of the Child Tax Credit to USD 3000-3600 per child with full refundability and monthly disbursement (July-December 2021) produced a measurable and immediate decline in monthly child-poverty rate of at least 4 percentage points (Center on Poverty and Social Policy at Columbia time-series), with the credit's December 2021 expiration producing a corresponding immediate reversal — providing high-frequency event-window evidence on near-instantaneous cash-transfer-to-poverty mechanics.
