Tonga in 1973
The population of Tonga in 1973 was 88,804. A decade earlier, in 1963, the population was 71,885; it has grown by 23.5% since.
Half of the population was younger than 16.8 years; 46.2% were children under 15 and 3.2% 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.
