Enter the number of males and females into the calculator to determine the parity ratio. The parity ratio is a demographic measure that provides the ratio of males to females in a given population.
Parity Ratio Formula
The following formula is used to calculate the parity ratio:
PR = M / F
Variables:
- PR is the parity ratio
- M is the number of males in the population
- F is the number of females in the population
To calculate the parity ratio, divide the number of males (M) by the number of females (F) in the population.
What is a Parity Ratio?
The parity ratio is a demographic indicator that compares the number of males to the number of females in a population. It is often used in population studies, sociology, and public health to understand the gender composition of a community or region. A parity ratio of 1 indicates equal numbers of males and females, while a ratio greater than 1 indicates more males, and a ratio less than 1 indicates more females.
How to Calculate Parity Ratio?
The following steps outline how to calculate the Parity Ratio.
- First, determine the number of males (M) in the population.
- Next, determine the number of females (F) in the population.
- Use the formula PR = M / F to calculate the parity ratio.
- Finally, calculate the Parity Ratio (PR).
- 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.
Number of males (M) = 120
Number of females (F) = 100
