Population includes all female respondents who reported current contraceptive method use weighted to reflect the U.S. female civilian population of the United States. The final multivariable model included the following variables: race–ethnicity, income as a percent of federal poverty level, age, born outside the United States, region, total number of live births, and ever having stopped using a non-LARC hormonal method as a result of dissatisfaction.
Possible significant difference at P<.05, needs further study.
Significant difference at P<.01.

Other types of insurance include Medicare, military health care, or other forms of government health care (not including Indian Health Service).
