The district was created in 1993, when the eastern part of Phaya Thai was split off to form a new district. The district is highly populated partly due to the concentration of apartments built by National Housing Authority. They are along Din Daeng Road and Pracha Songkhro Road.
The MRT passes along Din Daeng's eastern border (touching Huai Khwang) with five stations: Phra Ram 9, Thailand Cultural Centre, Huai Khwang, Sutthisan, and Ratchadaphisek.
