Global birthright indicators

Abstract

Global birthright indicators have been calculated for 179 countries. These are based on the provisions in force in citizenship laws on 1 January of each year, 2010-2020. They include all indicators for ius sanguinis and for ius soli at birth, but exclude ius soli after birth, i.e. acquisition of citizenship based on birth in the territory at the age of majority or after some time of residence. A score of 0 means that a mode of birthright acquisition does not exist; a score of 1 means that there are no restrictions for this mode of birthright acquisition. Scores between 0 and 1 represent degrees of restrictions or conditions for acquiring citizenship by birth. The previous version of Global birthright indicators has been calculated for 177 countries for 2016.
