Prior to 2012, Bago Region was officially split into two distinct regions – Bago East and Bago West (Official Gazette of the General Administration Department). It would be a landlocked region if not for around 60km of coastline along the Andaman Sea, and shares state borders with Yangon, Ayeyarwady, Rakhine, Magway, Naypyitaw, Kayin, and Mon. The capital city is Bago. Bago Region covers 39,405 km², and consists of 28 townships. It is the 5^th most populous state in the country with an estimated population of 4.85 million (2011 HMIS data) or 123 people per square kilometre. 17% of the population live in urban areas, and the remaining 83% in rural areas. Parts of Bago (4 of the eastern townships) have some of the heaviest landmine contamination in the country and, with Kayin, the highest number of recorded victims.
