We determined birth-control play with regarding weighted NSFG responses of females just who told you that they had got gender in the last three months and whom stated during the brand new interview which they weren’t pregnant, postpartum otherwise trying conceive hence none it nor their partner was sterile for any reason other than birth control.
NSFG participants who were maybe not only having fun with an extended-pretending birth-control into the three months just before interviews had been asked and this procedures they otherwise the spouse had made use of for a change gender because months.

I estimated pregnancies and you may pregnancy prices to have 1994 for ladies in respect on their years and you will relationship status at the conception, its brand spanking new intent regarding the conception together with decades difference between themselves in addition to their spouse.
•Births. To help you assess what number of pregnancies end inside the beginning because of the decades and you can marital status of the mother on conception, we utilized the level of births that taken place out of Oct 1994 due to Sep 1995 just like the a good proxy to your level of conceptions going on during 1994 that contributed to a beginning.
