One of the lowest population densities in Asia, at 19 persons per square km, and an estimated population of only 5.4 million people, belies the fact that Laos is home to 68 different ethnic groups. These fall into three groupings, based upon language, culture and traditions.
Within Laos approximately 60-70% of the population are said to be Theravada Buddhists, with the remaining population largely following Animism in the form of spirit (phii) worship.
The politics of Laos takes place in the framework of a single-party socialist republic.
