In demographics, the rate of natural increase (RNI) is the crude birth rate minus the crude death rate of a population.
When looking at countries, it gives an idea of what position in the Demographic Transition Model, but to find out how much a country is growing, the population growth rate should be observed.
Usually developing countries have a positive or high natural increase rate.
Developed countries have a negative/neutral or low natural increase rate, but many developed countries have their population increasing due to immigration despite their negative RNI.
The formula for the rate of natural increase is:  (Crude birth rate − Crude death rate) / 10, where birth and death rates are in per mil.
The result is the rate of natural increase in percentage form.
For example, Madagascar's crude birth rate (37.89) minus the crude death rate (7.97) is 29.92; divide that by 10 and the result is 2.992%, Madagascar's rate of natural increase.

Goods to which the tax is applied vary by province, as does the rate.
Moreover, for those provinces whose provincial sales tax is applied to the combined cost and GST, provincial revenues decline or increase with respective changes in the GST.
Of the provincial sales taxes, only the QST (and the HST) are value-added; the rest are cascading taxes.
