Survey phase	Supporting materials	Description
Design/Planning	Budget and timeline templates, and linked supplies list	Tools to help guide survey planning and logistics. Results from the supplies list can be copied/pasted directly into the budget tool.
	Sample size calculator	Online tool to help users calculate the sample size needed to measure their indicators of interest in their target population.
	Indicator sheets	Detailed definitions of all indicators that can be calculated from the RADAR coverage survey tool, including numerator, denominator, questions required for each indicator, and notes relevant for indicator calculation.
Sampling/Mapping	Cluster sampling tool	Desktop and excel-based application to sample clusters with probability proportional to population size.
	Mapping manuals, presentations, forms, and Open Data Kit (ODK) form	Guidance documents and materials to be used during training and implementation of household mapping/enumeration.
	Household sampling tool	Desktop and excel-based application to sample households using systematic random sampling.
	Deployment plan template	Template to guide the development of a deployment plan for mapping fieldwork.
Training and data collection	Interviewer and supervisor manuals and forms	Detailed manuals explaining the questionnaire question-by-question and providing guidance on how to conduct fieldwork and the roles and skills necessary for fieldwork for interviewers and supervisors. Manual sections that must be modified to users’ specific needs are highlighted in color, and they are designed to be used during training and during data collection. The manuals include sections on consent and confidentiality, as well as data quality assurance.
	Training agenda, presentations, and learning assessments	Tools for interviewer training, intended to be paired with the manuals and questionnaires for a comprehensive training. Sections that must be modified for the specific survey are highlighted.
	Word questionnaires	Questionnaires in Word format that can be used during interviewer training and/or for paper-based data collection.
	ODK questionnaires and manual	Open Data Kit (ODK) is an open-source computer-assisted personal interviewing (CAPI) platform. The RADAR ODK questionnaires contain the complete RADAR coverage survey, in ODK Excel format, for data capture on Android tablets. The RADAR ODK manual supplements open-source documentation on ODK to aid users who are implementing ODK surveys.
Data management & analysis	Data quality assessment indicators	Table of indicators (and corresponding R code) that can be used to assess the quality of incoming data and flag potential issues for follow-up in the field.
	Data processing scripts	Series of STATA .do files (code) that supports data management including cleaning variable names, final data cleaning, data preparation, and data archiving.
	Data analysis and tabulation scripts	Series of STATA .do files (code) that supports indicator generation and tabulation accounting for a complex survey design (requires adaptation by users to account for their survey design).
	Gender analysis guide	Describes rationale for including gender analysis in coverage surveys, and offers templates and quantitative examples of gender analysis from RADAR implementation.
Cross-cutting guidance	Implementation guide	Comprehensive step-by-step guide for entire coverage survey RADAR survey process from planning to data analysis.
	Coverage survey course	Online course introducing users to coverage surveys, presenting RADAR coverage survey tools, and guiding them through the steps to implement a coverage survey.
