Enter the population of the largest city and the population of the analyzed city into the Calculator. The calculator will evaluate the Rank Size Rule.

## Rank Size Rule Formula

n = P1/Pn

Variables:

- n is the Rank Size Rule (rank size)
- P1 is the population of the largest city
- Pn is the population of the analyzed city

To calculate Rank Size Rule, divide the population of the largest city by the population of the currently analyzed city.

## How to Calculate Rank Size Rule?

The following steps outline how to calculate the Rank Size Rule.

- First, determine the population of the largest city.
- Next, determine the population of the analyzed city.
- Next, gather the formula from above = n = P1/Pn.
- Finally, calculate the Rank Size Rule.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

population of the largest city = 40000

population of the analyzed city = 30000
