Purpose: The study examines worldwide public health insurance and ageing studies. This was accomplished by doing a thorough bibliometric analysis of publications published between 2002 and 2022 (till 31st May), which includes 479 articles for the analysis.

Design/methodology/approach: This study used the Web of Science database to analyse the vast quantity of data from the journals referenced above. VOSviewer creates network maps, keyword concurrences and cross-country co-authorship. The research analyses parameters like article distribution by year and citation frequency to determine top publications. After that, co-authorship, country co-authorship and keyword co-occurrence bibliometric network maps are shown.

Findings: The finding of the study reveals that the year 2020 is the most productive year for publication; BMJ Open is referred to as the most productive journal in this area, and "Depression in the Elderly" is the most referenced paper. The US has published the highest number of articles. We've seen 21 authors work with "Akishita and Ishizaki". The USA is the most collaborative author with other countries and conducted a keywords-based cluster analysis in which "Public health insurance, older adults and long-term care" are the most frequent keywords in this domain.

Originality/value: This article aligns with the current literature on elderly public health insurance. The authors utilize bibliometric analysis to provide a more comprehensive and robust understanding of this area. Those interested in conducting further research in this field can use the findings of this study as a guide.
