Guam Population Pyramid 2001
Guam in 2001
In 2001, Guam had a total population of 161,330 people. A decade earlier, in 1991, the population was 141,074; it has grown by 14.4% since.
Half of the population was younger than 27.5 years; 30.2% were children under 15 and 5.4% 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.
