Global Blood Type Distribution Analysis: A Comparative Study
Abstract
This study presents a comprehensive analysis of global blood type distribution across 126 countries, with an emphasis on identifying patterns and anomalies in blood group prevalence. Utilizing a dataset consisting of ABO and Rh factor percentages by country, we conduct exploratory data analysis using Python to uncover demographic insights and potential medical implications. The findings provide valuable references for healthcare planning, blood bank logistics, and genetic studies on population diversity.

Introduction
Blood types, defined primarily by the ABO and Rh systems, are critical in transfusion medicine, organ transplantation, and population genetics. The distribution of blood types varies significantly across populations due to evolutionary, geographic, and historical factors. Understanding these patterns not only enhances clinical preparedness but also supports anthropological and epidemiological research.
Conclusion
This analysis offers a detailed view of global blood type distributions, revealing patterns shaped by genetic, evolutionary, and geographic factors. O+ remains the most prevalent, while AB- is the rarest. These insights are crucial for:
Blood bank management
National health policy
Global humanitarian planning
Future work could incorporate:
Geographical plotting by continent
Time-based trends if historical data is added
Correlation with disease prevalence and genetic ancestry
