The formula to calculate the Contraceptive Prevalence Rate (CPR) is:
\[ \text{CPR} = \frac{\text{WU}}{\text{TW}} \times 100 \]
Where:
Let's say the number of women using contraception (WU) is 500 and the total number of women (TW) is 2000. Using the formula:
\[ \text{CPR} = \frac{500}{2000} \times 100 = 25\% \]
So, the contraceptive prevalence rate is 25%.
Definition: The contraceptive prevalence rate is the percentage of women of reproductive age who use (or whose partners use) a contraceptive method at a given point in time.
Formula: \( CPR = \frac{W_{c}}{W_{t}} \times 100 \)
Example: \( CPR = \frac{500}{1000} \times 100 \)
Definition: The modern contraceptive prevalence rate is the percentage of women of reproductive age who are using modern contraceptive methods.
Formula: \( MCPR = \frac{W_{mc}}{W_{t}} \times 100 \)
Example: \( MCPR = \frac{400}{1000} \times 100 \)
Definition: The contraceptive prevalence rate per country is the percentage of women of reproductive age using contraception in a specific country.
Formula: \( CPR_{c} = \frac{W_{c}}{W_{t}} \times 100 \)
Example: \( CPR_{c} = \frac{600}{1200} \times 100 \)
Definition: Statistics on contraceptive use provide data on the prevalence and types of contraceptive methods used by women of reproductive age.
Formula: \( SU = \frac{W_{c}}{W_{t}} \times 100 \)
Example: \( SU = \frac{700}{1400} \times 100 \)
Definition: The percentage of women using contraceptives is the proportion of women of reproductive age who are using any form of contraception.
Formula: \( PW = \frac{W_{c}}{W_{t}} \times 100 \)
Example: \( PW = \frac{800}{1600} \times 100 \)
Definition: Contraception methods effective rates indicate the effectiveness of different contraceptive methods in preventing pregnancy.
Formula: \( ER = \frac{P_{f}}{P_{t}} \times 100 \)
Example: \( ER = \frac{90}{100} \times 100 \)
Definition: The current contraceptive status among women refers to the present use of contraceptive methods by women of reproductive age.
Formula: \( CS = \frac{W_{c}}{W_{t}} \times 100 \)
Example: \( CS = \frac{850}{1700} \times 100 \)
