Thailand Population Pyramid 1987
Thailand in 1987
As of 1987, Thailand counted 52,074,105 inhabitants. A decade earlier, in 1977, the population was 42,843,974; it has grown by 21.5% since.
Half of the population was younger than 22.8 years; 32.4% were children under 15 and 3.7% were 65 or older. This is an expansive pyramid — each cohort of children is larger than the one above it, the signature of high birth rates and rapid growth.
