The Dual citizenship acceptance has progressed faster in the Americas and Oceania and slower in Africa and Asia. The acceptance in Europe follows the global trend.

By 2019, however, 75% of countries maintain a more tolerant approach towards dual citizenship and allow citizens to voluntarily acquire the citizenship of another country, without automatic repercussions for the citizenship of origin.

Most of these states, though not all, allow citizens to voluntarily renounce their citizenship after they have acquired another citizenship.

 

Dual citizenship trends

 

The dataset charts the rules that existed in near all states of the world since 1960 with regard to the loss or renunciation of citizenship after a citizen of a respective state voluntarily acquires the citizenship of another state.

The Dataset also distinguishes between three basic rules (with some variations):

  • The voluntary acquisition of another citizenship leads to the loss of the citizenship of the country of origin.
  • The voluntary acquisition of another citizenship does not lead to the loss of the citizenship of the country of origin, but citizens have the possibility to voluntarily renounce their citizenship of origin.
  • The voluntary acquisition of another citizenship does not lead to the loss of the citizenship of the country of origin and citizens do not have the possibility to voluntarily renounce their citizenship of origin.
