The gender, age, region, ethnicity at two education levels of percentage were calculated and the <em>χ</em><sup>2</sup> test was executed. <strong>Result:</strong> 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). <strong>Conclusion:</strong> 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
