^Calculated, when available, from the latest national censuses or most recent official estimates (many of which are cited in their respective column), using the exponential formula shown in the list of countries by past and projected future population article. This is done to normalize the different populations to a unique date, so that they are really comparable.
^It corresponds to the following formula: projection2015/projection2014x100-100.
^It corresponds to the calculation: projection2015*annual_growth/100.
^It corresponds to the formula: LN(2)/LN(growth/100+1), which produces exactly the same result as LOG10(2)/LOG10(growth/100+1).
^Includes the disputed territory of Crimea, although it is not internationally recognized as a part of Russia.
