Appendix Part 1 describes the methodology used to estimate the incidence of abortion, total pregnancy and unintended pregnancy in India. Part A is organized according to the three major components used to estimate abortion incidence in India. For each component, we discuss data sources, adjustments to available data, sensitivity analyses and in the case of one component, how state-level estimates were used to calculation national results. Component 1: Facility based abortions. These include induced abortion performed in facilities with the capability of performing abortion services: public and private hospitals, clinics, community health centers, primary health centers, maternity and nursing homes, medical colleges and few other types of facilities. Component 2: Medication abortions outside facilities. These include abortions using medication abortion drugs, obtained and administered outside of government, private and nonprofit health facilities. Component 3: Other abortions. These abortions are those obtained outside of health facilities and are not medication abortions. They may include abortions using a range of methods used by other non-medical providers or self-induced abortions. Part B discusses calculations for estimating the national total number and rates of abortion, total pregnancy and its components, intended and unintended pregnancy in India in 2015. Appendix Part 2 provides detail about the design and implementation of the Health Facility Survey (HFS). It includes information about the sample design; existing lists of facilities and a listing activity, which was undertaken for some categories of facilities for which lists of the universe of facilities do not exist; results of the fieldwork; and the calculation of sample weights. Appendix Part 3 provides the Hindi/English version of the Health Facility Survey questionnaire. The questionnaire was also translated into the languages of the study states for Assam, Gujarat and Tamil Nadu.
