Analysis and Mapping of Scientific Literature on Detention and Deportation of International Migrants (1990-2022)

Millions of people cross political borders yearly without having the proper documents. This has led to increased detention and deportation practices in destination countries for reasons related to security and sovereignty. The objective of the current study was to analyze and visualize research publications on the detention and deportation of migrants to identify current research hotspots, research gaps, and potential future research in the field. Relevant research articles were obtained from the Scopus database for the study period from 1900 to December 31, 2022. The analysis included presentations of key contributors to the field and visualization of topics, themes, and international collaboration. In total, 906 articles were found. The earliest was in 1982. The majority of articles were published in journals within the subject areas of social sciences and humanities. The number of publications showed a steep rise from 2011 to 2022. The Journal of Ethnic and Migration Studies was the most prolific, but publications in the Citizenship Studies journal received the highest number of citations per article. Researchers from the United States contributed the most. Mexico ranked fifth in the number of publications. Oxford University was the most prolific institution, followed by three universities in Australia. The majority of articles were single-authored, indicative of limited author-author collaboration. Research hotspots in the field were "human rights" and "mental health". The detention and deportation of Mexican and other Latino migrants in the United States constituted a distinct research theme in the field. International research collaboration was limited by geographical proximity (e.g., the United States and Mexico) or common language (e.g., the United Kingdom and Australia). Future research topics should focus on alternatives to detention, family separation, and healthcare services for detained migrants. Research activity on detention and deportation is required from all world regions, including the source countries of migrants. Future research should promote alternatives to traditional detentions. The contribution of countries in Africa, the Middle East, and South-Eastern Asian regions needs to be encouraged. Future research on the detention and deportation of non-Latino migrants is highly required.
