Methodology
Methodology notes
Adolescent pregnancies are the sum of all U.S. resident live births, induced abortions, and fetal losses to females aged 15 to 19 years. Data on live births are counts of all births to U.S. residents occurring in the United States, as reported to the National Vital Statistics System. Estimates of induced abortion are based on reports by CDC and The Guttmacher Institute's national estimates of abortions, based on survey responses in a census of all known abortion providers, are disaggregated by age, race, and geography according to proportions estimated by CDC's National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP), based on induced abortion data reported to the CDC by selected state health departments. Fetal losses refer to pregnancies that end in miscarriage, stillbirth, or ectopic pregnancy and are estimated as a proportion of births and of abortions. The total population of females aged 15-19 is obtained from U.S. Census data.
History
1. Because Healthy People 2030 objectives have a desired direction (e.g., increase or decrease), the confidence level of a one-sided prediction interval can be used as an indication of how likely a target will be to achieve based on the historical data and fitted trend.
