I used Google Fusion Tables to map this based on the data from the Bangkok Metro Administration.
It shows how each of the capital's fifty distrcits ranks in term of number of
population, households and population density.
Interestingly, the two most crowded disctricts,
Pom Prap Sattru Phai and Samphanthawong, home to the hectic China Town, still lack access to the MRT underground train
while car traffic in the areas is known to be disastrous. Outside the inner Bangkok, Din Daeng district
remains the prime resident area for Bangkokians.
