  • NATURAL INCREASE:  The difference between the number of live births and the number of deaths occurring during a given period, usually a calendar year divided by the mid-year population of that period* (usually expressed per 100 (10^2) or 1000 (10^3) inhabitants).
  • AVERAGE POPULATION:  The average population during a calendar year, generally calculated as the arithmetic mean of the population on two consecutive years.
  • REFERENCE PERIOD:  Period to which the information refers and which may be a specific day or a time interval (month, fiscal year, calendar year, among others).
Formule RNI=[SN(t-1, t)/[P(t)+P(t-1)]/2]*10^n

P(t)=Population at moment t;
P(t-1)=Population at moment (t-1);
NB(t-1,t) = Natural balance between the moments (t-1) e t;
n=2 ou 3.
