Thailand Population Pyramid 2004
Thailand in 2004
In 2004, Thailand had a total population of 65,452,047 people. A decade earlier, in 1994, the population was 58,260,854; it has grown by 12.3% since.
Half of the population was younger than 31.7 years; 22.6% were children under 15 and 7.2% 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.
