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 Kenya website, as well as a description of the data sources and analysis methods used in each of the website’s themes.

The TCDI Kenya 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 Kenyan tobacco control community’s needs. This document outlines our overall website methodology.

1. Identifying Stakeholder Needs

In June and August 2020, the TCDI team selected 20 tobacco control stakeholders (see the full list). We conducted short interviews with each one to explore how they make tobacco control 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 organisations and academia.

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. The workshop attendees were requested to vote for the top eight data gaps they wanted to see featured on the dashboard. This process produced 7 priority data gaps and 7 data format guidelines:

Priority Data Gaps

  1. Mortality and morbidity from tobacco use
  2. Tobacco agriculture
  3. Tobacco taxation
  4. Cessation services
  5. Enforcement of existing tobacco control laws
  6. Prevalence of tobacco use
  7. Tobacco industry interference

Preferred data format

  1. Simple and easy to understand
  2. Trustworthy data with clearly stated sources
  3. A data repository with data from multiple sources in one place
  4. Online, interactive tool with data that is easy to manipulate
  5. Regularly updated
  6. With downloadable briefs
  7. Kenya, East Africa or Africa-specific information

During the plenary discussion of the prioritized top data gaps, it became apparent that there were a few gaps that may have been mentioned rarely during the assessment but were of high interest to the stakeholders. These data gaps included ‘tobacco taxation’ and ‘enforcement of existing tobacco control laws’. 

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 analysed by the team’s economists using statistical software such as Stata. 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 colours) 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 20 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 analyse 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.
