: Population Characteristics
The estimated population of Bangladesh (2001) was
131,269,860, making Bangladesh one of the ten most
populous countries. The overall density, 890 persons
per sq km (2,304 persons per sq mi) in 2001, is
much higher than that of other countries except
for microstates such as Singapore. Bangladesh supports
a large rural population, with 21 percent of the
Bangladeshi people classified as urban in 1999.
The distribution of the population is relatively
even, except in the sparsely populated Chittagong
Hill Tracts District and the almost totally uninhabited
Sundarbans. Most of the people are relatively young,
nearly 60 percent being under the age of 25 and
only 3 percent being 65 or older. Life expectancy
at birth is 61 years.
