Abstract: The indexes numbers’s rol is to measure and to interpret the average variation in time, space or in relation with other systems of reference, in relative sizes, of the levels for the variables who belong to the statistical units from a collectivity. The indexes achieve a statistical analysis of the movement and of the change for these phenomenons. Therefore, the indexes are extremely importants in to underline the dynamic life which surrounds us.
