It covers the south-easternmost areas of the country, with a total area of 33,771.18 km2 and a population at the 2011 census of 28,423,019.

Administration
Chittagong division is subdivided into eleven districts (zilas) and thence into 99 sub-districts (upazilas). The first six districts listed below comprise the north-western portion (37.6%) of the division, while the remaining five comprise the south-eastern portion (62.4%), the two portions being separated by the lower (or Bangladeshi) stretch of the Feni River; the upland districts of Khagrachhari, Rangamati and Bandarban together comprise that area previously known as the Chittagong Hill Tracts. Before 1995, the four districts of Sylhet Division were also a part of Chittagong Division.
