MACIMIDE: Global Expatriate Dual Citizenship Rules Since 1960

The MACIMIDE Global Expatriate Dual Citizenship Dataset charts the rules in nearly all states worldwide since 1960 regarding loss or renunciation of citizenship after voluntary acquisition of another citizenship. It was created by Maarten Vink of Maastricht University. The central variable, dualcit_cat, reflects a country's legal position on expatriate dual citizenship as of January 1st of each reference year.

• Comparing countries' legal positions on automatic loss of origin citizenship using the dualcit_binary variable.

• Studying the relationship between expatriate rights and national legislation based on references to specific legal provisions.
