摘要	The migrant integration index developed by Harder, Hainmueller, Laitin and colleagues in 2018 is a short, validated survey instrument that measures how integrated an individual immigrant is across six distinct dimensions: psychological, economic, political, social, linguistic, and navigational. Earlier integration research suffered from a proliferation of ad hoc, single-dimension proxies — employment alone, or language alone — that were not comparable across studies, groups, or countries. The IPL index, named for Stanford's Immigration Policy Lab, instead defines integration as inherently multidimensional and provides standardized batteries — a twelve-item short form (IPL-12) and a twenty-four-item long form (IPL-24) — that aggregate the six dimensions into a single, comparable score for each person. Critically, the instrument is designed and validated psychometrically, with the short form shown to track the long form and external outcomes closely, so researchers can capture the full breadth of integration in just a few minutes of survey time. The result is a portable, individual-level measurement tool that brings consistency to a field long fragmented by incommensurable indicators.	The Migrant Integration Policy Index, known as MIPEX and maintained by the Migration Policy Group and CIDOB with its 2020 edition by Solano and Huddleston, measures not how integrated immigrants are but how well a country's policies support their integration. It scores national laws and regulations across eight policy domains — labour-market mobility, family reunification, education, health, political participation, permanent residence, access to nationality, and anti-discrimination — by having country experts code each policy against a benchmark of the highest equal-treatment standard. Each indicator is scored on a simple scale anchored to legal text, domain scores are averaged, and the eight domains combine into a single composite that ranks dozens of countries on a comparable 0-to-100 scale. The result is a transparent, benchmarked scorecard of integration policy that lets researchers, governments, and advocates compare national approaches and track them over multiple editions. MIPEX measures the policy environment as an input to integration, complementing individual-level outcome measures such as survey-based integration indices.
