how is the rate of natural increase determined
Rate of natural increase Within the study of demography, the rate of natural increase (RNI) is classified as the crude birth rate minus the crude death rate.[1]
Inflation In economics, inflation is a sustained increase in the general price level of goods and services in an economy over a period of time.[1] When the price level rises, each unit of currency buys fewer goods and services; consequently, inflation reflects a reduction in the purchasing power per unit of money – a loss of real value in the medium of exchange and unit of account within the economy.[2][3] A chief measure of price inflation is the inflation rate, the annualized percentage change in a general price index, usually the consumer price index, over time.[4] The opposite of inflation is deflation.
