Objective The characteristics and survival condition of new diagnosed cases of pneumoconiosis in Nanjing during 2006 to 2019 was analyzed, in order to provide reference basis in formulating controlling measures.

From 2014 to 2019, the incidence rate was 13.9, 5.6, 1.8, 2.0, 1.4 and 1.6 per 10 000 people, respectively, showing a downward trend.
