The formula to calculate the Rank Size Rule (n) is:
\[ n = \frac{\text{P1}}{\text{Pn}} \]
Where:
The rank size rule is a measure used in urban geography to describe the relationship between the population sizes of cities within a region. It suggests that the population of a city is inversely proportional to its rank in the urban hierarchy. For example, the second largest city is expected to have half the population of the largest city, the third largest city is expected to have one-third the population, and so on.
Let's assume the following values:
Using the formula:
\[ n = \frac{8,000,000}{2,000,000} = 4 \]
The Rank Size Rule (n) is 4.
