Thailand Population Pyramid 2001
Thailand in 2001
As of 2001, Thailand counted 63,651,142 inhabitants. Over the previous ten years the population grew by 14.4%, up from 55,637,434 in 1991.
Half of the population was younger than 30.5 years; 23.9% were children under 15 and 6.4% were 65 or older. The pyramid is stationary: cohort sizes are roughly even through the younger ages, reflecting fertility close to replacement level and slow population change.
