Understanding country differences in production and human capital in plastic surgery research is crucial in identifying current and future leaders in the field. In this study, we document each country's human capital and productivity in plastic surgery research. A web scraping algorithm was deployed on PubMed to retrieve information on every publication and every first author in 10 major research outlets in plastic surgery between 2015 and 2021. Each country's human capital in the field is proxied by the number of first authors affiliated with that country. We compare aggregate patterns and volume trajectories of publications affiliated with 110 countries in the context of their human capital. We find that over the studied period, two countries, the USA and China, are represented in roughly 50% and 45% of global research output and first authors, respectively, in plastic surgery. Specifically in the USA, California has the highest number of affiliated first authors and publications compared with other States. Our findings reveal the clear dominance of the USA in plastic surgery research production. No specific US State stands out in the nation as much as the USA does in the global ranking of plastic surgery publications. This suggests that US plastic surgeons across the nation aim to publish. Our global analysis also suggests that countries with a higher share of first authors relative to their research output may have greater capacity to expand their research output in the future. This journal requires that authors assign a level of evidence to each article.
