Dictionary of population terms
rate of natural increase
коэффициент естественного прироста
- demographic indicator, the relative
index of natural increase of population size of some territory during
some time period.
Sources for calculation of RNI are vital statistics data on number
of deaths and births, used for measuring population natural increase,
and estimates of population size of this region. Value of RNI is
equal to the difference between crude birth rate and crude death
Usually RNI is given for the period equal to 1 year and computed
as the result of dividing the one-year population natural increase
by the mid-year population size at the given territory. Usually
RNI is scaled to per cent per annum to provide convinience.
Computation of RNI for population of Russia and its regions is being
made by Federal State Statistics Service
(Rosstat, the former Goskomstat) and these data are published
for example in The
demographic yearbook of Russia.
Sources of data for other countries of the world: Eurostat;
INED. Base de données.

In most countries of the world RNI
ranges in 2005 between -0,7 per cent (Ukraine) and +3,4 per
cent (Niger, Palestinian territory) per year, and for the whole
world it was 1,2 per cent per annum.
