Demography of Bangladesh

Bangladesh is the most densely populated non island nation in the world. With approximately 125 million inhabitants living in an area of 55,813 square miles, there are about 2,240 persons per square mile. The majority of the population (98 percent) is Bengali, with 2 percent belonging to tribal or other non-Bengali groups. Approximately 83 percent of the population is Muslim, 16 percent is Hindu, and 1 percent is Buddhist, Christian, or other. Annual population growth rate is at about 2 percent.

Infant mortality is approximately seventy-five per one thousand live births. Life expectancy for both men and women is fifty-eight years, yet the sex ratios for cohorts above sixty years of age are skewed toward males. Girls between one and four years of age are almost twice as likely as boys to die.

In the early 1980s the annual rate of population increase was above 2.5 percent, but in the late 1990s it decreased to 1.9 percent. The success of population control may be due to the demographic transition (decreasing birth and death rates), decreasing farm sizes, increasing urbanization, and national campaigns to control fertility (funded largely by other nations).
