Most of the residents are Marshallese, who are of Micronesian origin and migrated from Asia several thousand years ago. A minority of Marshallese have some recent Asian ancestry, mainly Japanese. About one-half of the nation's population lives on Majuro, the capital, and Ebeye, a densely populated island. The outer islands are sparsely populated due to lack of employment opportunities and economic development. Life on the outer atolls is generally traditional.
