Bibliometric Analysis on International Trends of Research on Single-Person Housing

The purpose of this study is to understand the international trends of previous studies related to single-person housing and compare the last ten years and the preceding decades. Using bibliometric analysis, the publication patterns of literature by year, the changes in research achievements and topics over time by country and journal were reviewed. The reviewed articles were extracted from Scopus using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. To analyze this massive amount of extracted data efficiently and systematically, the Bibliometrix R Package and VOSviewer software was used. A network and cluster analysis of keywords was performed that examined a nation’s performance in terms of article production, research exchange and a journal’s performance involving the field of topical research. The results revealed that over the last ten years, single-person households have rapidly increased along with the research done on single-person housing. Over the last decade, studies on single-person housing have diversified, becoming more complex. Asia-Pacific countries have emerged and significantly contributed to the literature on single-person housing studies. The academic fields of these journals have diversified as it seems to relate to the diversification of research topics. This study could be used as basic data for understanding single-person housing and in solving future demographic and housing problems.
