Citizenship Policy Index (CPI)

Description
The Citizenship Policy Index (CPI) addresses policies for citizenship acquisition for the EU15 member states (for years 1980 and 2008), and other 10 EU member states entered in 2004 (for 2004). CPI consists of the simple aggregation of three factors: whether or not a country grants jus soli, the minimum length of residency requirement for naturalization; whether or not naturalised immigrants are allowed to hold dual citizenship. It also takes into account language and civic integration requirements that a number of countries have mandated as a condition for naturalization. Each component is scored on a 0-2 scale, yielding a 0-6-point range for the total index. CPI draws on in-depth research by individual country experts, within a common methodological framework. CPI allows for distinguishing between three groups of countries, depending on whether their citizenship policies can be characterised as ‘restrictive’ (scores between 0 and 1.5), ‘medium’ (over 1.5 but less than 4) or ‘liberal’ (4 and above).
