Ida-Viru County (Estonian: Ida-Viru maakond, Russian: И́да-Ви́руский уезд, Ída-Víruskij Jezd), 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 2014 Ida-Viru County had a population of 149,483 – constituting 12.6% of the total population in Estonia.
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 governor of Ida-Viru county is Andres Noormägi.
In January 2010, the population of Ida-Virumaa was 168,656, which makes it the second largest county in Estonia (after Harjumaa, which includes Tallinn). 44.6% of the population are men and 55.4% women.
By ethnic origin, on 1 January 2013, 72.8% of the population were Russians, 19.5% were Estonians, 2.3% were Ukrainians, 2.2% were Belarusians and 0.9% were Finns. This is dramatically different from the rest of Estonia, where most counties are over 80% ethnic Estonian.
