Data and Methods

In this page we explain the process followed by Development Gateway, in partnership with the University of Cape Town, in the development of the TCDI Ethiopia website, as well as a description of the data sources and analysis methods used in each of the website’s themes.

The TCDI Ethiopia website was developed by Development Gateway in partnership with the University of Cape Town. The website is intended to respond to the needs of government, civil society and academic stakeholders by providing access to demand-driven, high-quality data on national tobacco prevalence, products, and policies. The design, functionality and content for the website are led by the Ethiopian tobacco control community’s needs. This document outlines our overall website methodology.

1. Identifying Stakeholder Needs

In November and December 2020, the TCDI team conducted an assessment that involved 14  stakeholder organizations  working in Ethiopia. A total of sixteen individuals participated in this assessment: nine government officials, four civil society organizations,two academics and one expert from an international non-governmental organization (INGO).We conducted short interviews with each one to explore how they make decisions, the data used for these decisions, potential data gaps, and their preferred format for receiving data (e.g. graphs, short paragraphs, infographics). Stakeholders included representatives of government, civil-society-organizations and academia. Here is the full list of organizations that engaged with TCDI either in the assessment, stakeholders consultations, stakeholder feedback sessions and/or the co-design workshop.

2. Reviewing Stakeholder Feedback and Prioritising Needs

The stakeholder feedback was documented during the interviews and later analysed to identify cross-cutting data gaps and the stakeholders’ preferred formats for receiving information. The feedback was distilled according to the frequency and urgency with which each was mentioned by the stakeholders. This process produced 7 priority data gaps and 7 data format guidelines:

Priority Data Gaps

  1. Prevalence of Tobacco Use
  2. Illicit trade of tobacco products
  3. Economic and health burden of tobacco use
  4. Tobacco Taxation
  5. Tobacco Industry Interference
  6. Tobacco Cessation
  7. Enforcement of tobacco control laws

Preferred data format

  1. Short, concise and attention grabbing
  2. Simple and easy to understand
  3. Clear visuals
  4. Factsheets and individual stories
  5. Trustworthy data with clearly stated sources
  6. A data repository with data from multiple themes in one place
  7. Ethiopia specific information

The preferred data gaps and format were confirmed with the stakeholders in an interactive workshop in June 4th 2021, during which each data gap was discussed further to identify the sub-thematic components stakeholders wanted to learn more about (for instance, for the tobacco agriculture theme, various sub-themes, such as employment and health risks etc., were identified).

3. Research and Analysis

The TCDI team conducted research and data analysis for each theme, including systematic research of reliable primary data (e.g. data collected by academic institutions, global foundations or governments) and secondary data (e.g. peer-reviewed academic articles). Where required, the primary data were analyzed by the team’s economists and epidemiologists using statistical software such as Stata and R. The stakeholder needs were reviewed against the primary and secondary data available, relevant statistics and graphs were produced, and explanatory text was written.

4. Website Design

Using the 7 data format guidelines as a starting point, the TCDI team designed the visual elements and functionality of the website. This process included designing the visual elements (infographics, chart formats and colors) and the user functionality (menus, data exports and search functionality).

5. Expert Review

At least two expert tobacco-control academics were selected per theme to review the quality and reliability of the content. Their feedback was integrated into the text and the design of the website.

6. Stakeholder Review

The 16 tobacco-control stakeholders were invited to small online group discussions during which they opened the website link for the first time, shared their screens and narrated their experience as they navigated through the website. The TCDI team documented the process, noting down any areas for improvement, and evaluating whether the information addresses users’ data needs and the visuals are clear and easy to understand. All feedback was collated to produce a stakeholder feedback matrix.

7. Finalize Design

Using the stakeholder feedback matrix as a guide, the TCDI team conducted additional desk research (where required) to find and analyze data to fill any remaining data gaps. In addition, visual elements and functionality were redesigned wherever necessary. The changes were incorporated into the website themes and the website was published online.

8. Update Periodically

Periodically, the TCDI team will consult with experts, review newly available data, and update the website to reflect any changes, where necessary. Please fill out the Showcase Your Work form if you have newly available data or publications you would like to share.
