Bangladesh is divided into 8 divisions (bibhag) and 64 districts (jela, zila, zela), although, these have only a limited role in public policy.

Traditionally, Bangladesh has been divided into four regions by the fertile Ganges-Brahmaputra delta;[2] formed by the confluence of the Ganges (local name Padma or Pôdda), Brahmaputra (Jamuna or Jomuna), and Meghna rivers and their various tributaries.

Upazilas are similar to the county subdivisions found in some Western countries.

Like India, City corporations do not fit neatly into upazilas, despite some deemed as "sadar", indicating urban characteristics.

Despite the meaning, thanas functioned much as an administrative and geographic region, much as today's upazilas.

In 1982 thanas were re-termed to as upazilas with provisions for semi-autonomous local governance.
