Table 1

Description of the variables and measurements for the multilevel logistic regression analysis of the determinants of contraceptive method utilization among young women in Ethiopia, June-July, 2018.

Variables	Descriptions	Measurements
Dependent variable
Contraceptive method utilization	Using any contraceptive methods (modern or traditional) during the time of the survey	A woman who was using any one of the contraceptive methods was coded as “1” and who was not using as “0”

Place of residence	The usual place of residence where the woman lives	Urban kebele was coded as “1,” and rural kebele was coded as “0”
Wealth quintiles	House hold assets, home, land, and livestock’s ownership were assessed, and wealth index was computed by using principal component analysis (PCA)	The wealth status was categorized into five groups and ranked from the poorest to the wealthiest quintile
Religion	The religious background of the respondent	Each religion was entered and later recoded as “Orthodox Christian,” “Muslim,” “Protestant,” and “Others.” Others were merged because they were very few for logistic regressions
Level-1 (lower-level) independent variables	Individual level variables
Age group	Age of women at interview in completed years	Asked in completed years and later categorized into “15-19” and “20-24”

Knowledge on contraceptive methods	The women were asked whether they have heard each of the 12 methods of contraceptive methods, and a composite knowledge score was produced by using PCA	Mean score was computed for the composite knowledge score; those scored above or equal to the mean score were categorized into having “Good knowledge,” and those who scored less than the mean were categorized as; “Poor knowledge”
