Government
Nimba County is one of fifteen counties of Liberia. During the nearly three-decade administration of William V.S. Tubman (1944–1971), the region now called Nimba County was one of three of Liberia's provinces: Western Province, Eastern Province, and Central Province. In the sixties, Tubman reorganized these provinces into counties. Central Province became what is known as Nimba County.
Before the First Liberian Civil War broke out in 1989, the county had a population of over 310,000 people. The top executive in the counties is a County Superintendent, appointed by the president of the county. The previous County Superintendent, D. Dorr Cooper, who is the chief administrative officer, was appointed by President Ellen Johnson Sirleaf in 2017. He was re-appointed in 2018 by President George Weah after a change in administrations. The current County Superintendent is Kou Meapeh Gono, appointed by President Joseph Boakai in 2024.
