British colonial rule introduced Western elements of culture to Myanmar. Myanmar's education system is modelled after that of the United Kingdom. Colonial architectural influences are most evident in major cities such as Yangon. Many ethnic minorities, particularly the Karen in the southeast and the Kachin and Chin who populate the north and northeast, practice Christianity. According to ''The World Factbook'', the Burman population is 68% and the ethnic groups constitute 32%. In contrast, the exiled leaders and organisations claim the country is 40% ethnic.
