This is done to normalize the different populations to a unique date, so that they are really comparable. Jump up ^ It corresponds to the following formula : projection / projection x100 - 100. Jump up ^ It corresponds to the calculation : projection * annual_growth / 100. Jump up ^ It corresponds to the formula : LN ( 2 ) / LN ( growth / 100 + 1 ), which produces exactly the same result as LOG ( 2 ) / LOG ( growth / 100 + 1 ). Jump up ^ Islands claimed by Argentina.
