Abstract Objective To detect the spatial distribution and high‐risk clusters of lung cancer mortality for the years 2011–2013 in Shandong Province, China. The urban–rural differences in the spatial distribution and clusters of disease mortality were also examined. Methods Lung cancer mortality data were obtained from Shandong Death Registration System during 2011–2013, and were adjusted with the underreporting rate. The purely spatial scan statistics method was carried out using a discrete Poisson model. Results Seven significant spatial clusters of high mortality of lung cancer were detected in Shandong Province at the county level, mainly in the eastern, northern, central, and southwestern regions. The spatial distributions were different between urban and rural populations. Population aging influenced the distribution of lung cancer clusters for the urban and rural eastern region residents. Conclusions This study provided evidence for the presence of clusters of lung cancer mortality in Shandong, China, and found urban–rural differences in the clusters, which might be helpful in developing effective strategies to control lung cancer in different areas.
