The population of the growing region is projected to be 9,156,000 in 2015, up from 8,871,003 in 2010 (census count and adjusted). Although those figures are adjusted for citizens who have left for Bangkok or who moved to the region from elsewhere, as well as registered permanent residents (residency was problematic in the prior 2000 census), the figure is still misleading. There are still a huge number of migrant or informal workers, temporary workers and even stateless people and a large expatriate population, which are not included.
