Executive Summary

This interactive map illustrates the national coverage of a burn injury research project in China. It highlights the number of families affected by burns across 9 key cities. The household numbers are based on epidemiological estimates from a nationwide survey conducted in 2018. The goal is to visualize the geographic impact and reach of the research initiative.

Introduction

Severe burns have a profound impact on patients and their families. As part of a long-term follow-up research study, this project examines burn outcomes across several regions of China. By visualizing the coverage, we can better understand the spatial distribution of affected households.

Data Source and Processing

The city coverage data is derived from a 10-year epidemiological study of burn incidents in China (2009–2018). Using population-based estimates and hospital case volume, we estimate the number of households affected in each of the 9 cities included in this study.
