Abstract
The GLOBALCIT Citizenship Law Dataset includes information on the different ways in which citizenship can be acquired and lost across the world. The Dataset is organised around a comprehensive typology of modes of acquisition and loss of citizenship, which outlines, in a systematic way, 28 ways in which citizenship can be acquired and 15 ways in which citizenship can be lost. For each 'mode' of acquisition and loss of citizenship the typology outlines a standardised 'target person' which allows comparing rules applicable to similar groups across countries.
The GLOBALCIT Citizenship Law Dataset, v3.0 covers information on laws in force, for all modes of acquisition and loss of citizenship, in 191 states on 1 January of the three years 2020 – 2024; while for selected dual citizenship regulation modes, the Dataset covers information on laws in force in 201 states on 1 January of the 63 years 1960 – 2024. The Dataset will be updated periodically and the longitudinal coding will gradually be expanded to cover additional modes of acquisition and loss of citizenship, which will be included in subsequent iterations of the Dataset.
This repository includes three types of files, included in a zip-file for each version of the Dataset (‘GLOBALCIT Citizenship Law v3.0.zip’):
Codebook: codebook with metadata outlining the comparative methodology, categorical coding scheme and the sources of the Dataset ('codebook_v3.0.pdf') and, from v2, also a ‘Dual Citizenship Codebook’ with coding scheme and sources used for the longitudinal coding of dual citizenship indicators (‘codebook_v3.0_dual_citizenship.xlsx’); Country-Year file: data file coding the presence and type of provision regulating the acquisition or loss of citizenship in a country in a particular year, row-ordered by country (iso3) and year, and binary (_bin) and categorical (_cat) citizenship law variables in columns ('data_v3.0_country-year.csv', 13076 rows with variable labels in first row); Country-Year-Mode files: data files coding the presence and type of provision regulating the acquisition resp. the loss of citizenship in a country in a particular year, row-ordered by country (iso3), year and mode, and citizenship law variables with qualitative descriptions and quantitative codes in columns 'data_v3.0_country_year_mode_acq.csv', 32471 rows with variable labels in first row; 'data_v3.0_country_year_mode_loss.csv', 14326 rows with variable labels in first row).
