Where can we get this data if we deal with the Subject from Russian Federation? Our first step is the Federal State Statistics Service.
On this site you will find general statistical data about population, economy, regional development of the country etc. English version of the Federal State Statistics Service site is less informative and knowledge of Russian language is essential.
If your Subject is involved in international trade some important statistical data and regulations can be found at Federal Customs Service. English version of the site is also poor.
