Objective: This study aimed to clarify the death characteristics of esophageal cancer in Inner Mongolia and the population distribution with various education levels. Methods: The mortality rate of esophageal cancer was calculated using the monitoring point of Death Registry System in Inner Mongolia from 2009 to 2015. The gender, age, region, ethnicity at two education levels of percentage were calculated and the χ<sup>2</sup> test was executed. Result: The mortality rate of esophageal cancer was 10.10/105, China Adjustment Mortality was 10.97/10<sup>5</sup>, World Adjustment Mortality was 9.08/10<sup>5</sup> in Inner Mongolia. The death of esophageal cancer showed statistical significance at two educational levels (P < 0.05). High school and below accounted for 93.9% at the education level, and above high school accounted for 3.5%. In addition, there were significant differences in the percentage of death by gender, age and region at two educational levels (P < 0.05). Conclusion: Education level has a certain relation with the death of esophageal cancer. To improve the health level, health education plans can be formulated according to esophageal cancer prevention relevant policy with different education levels. 展开更多
