About the National Data

Data

Baseline: 60.3 percent of women aged 20 to 44 years at risk of unintended pregnancy used most effective or moderately effective methods of contraception in 2015-17

Target: 65.1 percent

Numerator
Number of women aged 20 to 44 years who are currently using most effective or moderately effective methods of contraception.
Denominator
Number of women aged 20 to 44 years who are at risk of unintended pregnancy.
Target-setting method
Percentage point improvement
Target-setting method details
Percentage point improvement from the baseline using Cohen's h effect size of 0.10.
1
Target-setting method justification
Trend data were not available for this objective. A percentage point improvement was calculated using Cohen's h effect size of 0.1. This method was used because it was a statistically significant improvement from the baseline.

Methodology notes

The most effective methods of contraception are: male or female sterilization, implants, and intrauterine devices or systems (IUD/IUS). Moderately effective methods of contraception are: injectables, oral pills, patch, ring, or diaphragm.

At risk of unintended pregnancy is defined as women who have ever had sex (with a man), are not sterile (for surgical noncontraceptive or nonsurgical reasons), or are neither pregnant, seeking pregnancy, nor postpartum.

History

Comparable HP2020 objective
Retained, which includes core objectives that are continuing from Healthy People 2020 with no change in measurement.

1. Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
