These tables show three-year aggregates of Oregon resident births by age of mother, age of father, and residence county. ZIP code information is also available for tables prior to 2008.
ADVISORY: These data should be used cautiously for teen births. Between 1993 and 1997, 44% of birth certificates where the mother was 17 or younger had no information on the father. Note also that information on the father is not added to the statistical file when paternity affidavits are filed after the close of the data year. Programs to prevent early childbearing are expanding their focus to include education and outreach programs to men.
