What it is
A Chiang Mai University study of Landsat scenes puts the built-up area at 13 km² in 1952 and 137 km² in 2009. Within the comprehensive-plan boundary, urban land went from 10.6 percent in 1989 to 12.1 in 2000 and 18.3 in 2009, with a model projecting 38 percent in 2010 to 80 percent in 2030; buildings rose a third between 2000 and 2013, a fifth of the growth outside zoned areas. The metropolitan area is put at 1,059,462 people over 3,142 km² in 2024.
The long version
Inference — every ring on this site was drawn around a city a fraction of this size. The outer ring was fixed in 1989, when the built-up area was a tenth of the plan boundary; by the time it closed the city was at the ring.
