Like the exponential growth rate, it does not take into account intermediate values of the series. It is applicable to compound growth over discrete periods.

Geometric growth rate: the growth rate over n periods calculated as r = exp - 1.

It does not necessarily match the actual growth rate between any two periods. The calculated growth rate is an average rate that is representative of the available observations over the entire period. No growth rate is calculated if more than half the observations in a period are missing.

Least-squares growth rate: the growth rate estimated by fitting a linear regression trend line to the logarithmic annual values of the variable in the relevant period.

It does not take into account the intermediate values of the series. This growth rate is based on a model of continuous, exponential growth between two points in time.

Exponential growth rate: the growth rate, r, between two points in time calculated from the equation r = ln(pn/p0)/n, where pn and p0 are the last and first observations in the period, n is the number of years in the period range, and ln is the natural logarithm operator.

To perform mathematical functions on the data over a specified time period, choose the type of operation from the dropdown menu, and then choose your time period. Select an appropriate weight variable (GNI, population, GDP, exports, imports, labor force or land area) from the Weight Indicator box, as shown above. No aggregate is shown if countries with missing data represent more than one third of the total population of your custom group.
