Teen Pregnancy, Induced Abortion, and Fetal Death data

This page focuses on data for pregnancy outcomes for teen pregnancies, fetal deaths, and induced abortions. For more comprehensive birth data, visit the Oregon Birth Data page.

Teen Pregnancy - Updated September 10, 2026

Finalized data on teen pregnancies can be found in two interactive dashboards. These data dashboards represent final statistics on pregnancy in Oregon. Final data has undergone extensive quality assurance and editing procedures compared to preliminary data. New pregnancy data are added each year in late summer to early autumn.

​Oregon teen pregnancy data includes births and induced abortions.

  • Pregnancy estimates are based upon the estimated number of teen births and induced terminations among Oregon teens; they do not include the number of fetal deaths or miscarriages (spontaneous abortions) which occur.

  • The estimation of teen births is considered to be relatively complete and includes births to resident teens even when they occur out-of-state. The estimation of teen abortions is based on all reported abortions to teenage residents of Oregon; however, because states often do not report abortions obtained within their borders to the state of residence as occurs with vital events such as birth and death, an unknown number of Oregon teens obtain abortion services out-of-state. As a consequence, estimates of teen abortions and teen pregnancies should be considered minimal in nature.

  • Other tables of teen pregnancy data from 2017 and earlier are available. Please contact ​CHS.Statistics@oha.oregon.gov for more information.

Quarterly year-to-date and preliminary teen pregnancy counts and rates

2026 - Moving teen pregnancy counts, rolling rates, and 2026 year-to-date data for age groups 10-17, 15-17, and 15-19 (updated 11/2026)​

​Final annual teen pregnancy counts and rates​​

​Final teen pregnancy data can be found in the Annual Tr​ends in ​Birth & Pregnancy data dashboard​.


​The Center for Health Statistics has developed a system to calculate preliminary teen pregnancy rates for 10-17, 15-17, and 15-19-year-olds at the state and county level.

Preliminary 12-Month Moving Total:

The 12-month moving total is the sum of monthly counts of teen pregnancies to each age group of Oregon residents (births and induced abortions* during the previous 12-month period)**



* For all tables associated with this project, abortion is defined as an induced termination of pregnancy, and does not include spontaneous abortions, also known as miscarriages, fetal demises, or fetal deaths.

** Rates and counts in counties where residents typically travel to other states to obtain medical services will reduce counts and rates until data are received from other states. This typically occurs a few months before the end of a calendar year. The reporting of abortions to the Center for Health Statistics is often delayed, which will also reduce counts and rates until the data are received. In addition, some states (i.e. California) do not report induced terminations of pregnancy of out-of-state residents to other states, which likely results in reduced counts for some counties. 

 

Preliminary Rolling Rate:

The pregnancy rate per 1,000 females within each age category is calculated by dividing the 12-month moving total pregnancies by the most recent population estimate for Oregon females, multiplied by 1,000. During the year, the data are under constant revision.

 

Population Estimates:

The most current population estimates will be used, and replaced when new estimates are available. Population data by sex and age are typically available in April following the estimate year. Because of this, up to ten months of the current year's rates will be calculated using the previous year's population estimates. Teen pregnancy rates will be affected in counties with rapidly changing population estimates for teen females. Population estimates are provided by the ​Population Research Center at Portland State University.


YTD Pregnancies:

Year-to-date (YTD) pregnancies are the sum of Oregon resident births and abortions as they are reported and updated quarterly to the Center for Health Statistics. The YTD figure is the actual number of pregnancies reported for the specific calendar year.


Preliminary and Final Rates:

Preliminary rates are undergoing final editing procedures, and may result in occasional and minor changes. Please label data as provisional or preliminary when reporting. Final rates for past years will not change and have been published in various vital statistics publications.​
