Siberian Federal District
Other sources may use either a somewhat wider definition that states the Pacific coast, not the watershed, is the eastern boundary (thus including the whole Russian Far East) or a somewhat narrower one that limits Siberia to the Siberian Federal District (thus excluding all subjects of other districts). In Russian, the word for Siberia is used as a substitute for the name of the federal district by those who live in the district itself and less commonly used to denote the federal district by people residing outside of it.
