Social security and pension trends. A bibliometric study

Abstract

This article presents a bibliometric analysis of trends in pension studies in the field of social security, using Zipf's law, Lotka's law and the h-index. The research focused on identifying productivity and citation patterns and determining the main research themes and trends. Through term frequency analysis, it was observed that the words "pensions," "social security," and "sustainability" are predominant, confirming Zipf's law. Lotka's law was validated by finding that a small group of authors is responsible for most of the publications, indicating a concentration in scientific production. The h-index calculation showed that the most prolific authors are also the most cited, reflecting their influence in the field. Thematic trends reveal a shift from implementing pension systems towards sustainability and reforms for regime changes. Furthermore, the geographical distribution highlighted a high concentration in developed countries with increasing international collaborations. These findings provide a comprehensive overview of research dynamics and offer recommendations for future research and policies in social security
