About the National Data

Data

Data Source:  National Survey of Family Growth (NSFG), CDC/NCHS

Baseline: 24.1 percent of sexually active females aged 15 to 19 years used a most or moderately effective method of contraception at last intercourse, as reported in 2015-17

Target: 36.8 percent

Numerator
Number of sexually active females aged 15 to 19 years who used a most or moderately effective method of contraception at last intercourse.
Denominator
Number of sexually active females aged 15 to 19 years.
Target-setting method
Minimal statistical significance
Target-setting method details
Minimal statistical significance, assuming the same standard error for the target as for the baseline.
Target-setting method justification
Trend data were not available for this objective. The standard error was used to calculate a target based on minimal statistical significance, assuming the same standard error for the target as for the baseline. This method was used because it was a statistically significant improvement from the baseline.
