Ida-Viru County (Estonian: Ida-Viru maakond), or Ida-Virumaa, is one of 15 counties of Estonia. It is the most north-eastern part of the country. The county contains large deposits of oil shale - the main mineral mined in Estonia. As oil shale is used in thermal power plants, the earth in Ida-Viru contains most of Estonia's energy resources. The capital of the county is the town of Jõhvi which is administratively united with the Jõhvi Parish. In January 2016 Ida-Viru County had a population of 146,506 – constituting 12.6% of the total population in Estonia.. It borders Lääne-Viru County in the west, Jõgeva County in the southwest and Russia (Leningrad Oblast) in the east.
The County Government (Estonian: Maavalitsus) is led by a Governor (Estonian: maavanem), who is appointed by the country's government for a term of five years. The current[when?] governor of Ida-Viru county is Andres Noormägi.
In January 2017, the population of Ida-Virumaa was 143,880, which makes it the third largest county in Estonia (after Harju and Tartu counties, which include the capital Tallinn and country's second-largest city Tartu). 44.6% of the population are men and 55.4% women.
In the aftermath of World War II, Estonia was occupied by the Soviet Union and large swaths of Ida-Viru County underwent ethnic cleansing by the Soviet authorities. Estonians, who were forced out of the major population centers, including Narva, were replaced by colonists from Russia. As a result of mass migration from the Soviet Union, Ida-Viru County is now the only county in Estonia where ethnic Russians have largely replaced the indigenous Estonian population.
