SA COVID-19 Project: Vulnerable Communities Map

30 March 2020, by Stephen van der Heijden

COVID-19 is one of the most severe public health challenges in recent memory. South Africans with pre-existing illnesses are particularly vulnerable but a map of the most affected communities could help the government plan their response. That’s why we’re calling on companies and developers in the community to help build a beta-map.


Thank you to everyone who volunteered to help build this tool. The project is now closed. You can find out more about the vulnerable communities mapping tool here.

Project Background

The SDG Hub at the University of Pretoria has been tasked with creating a health-map of our communities that are particularly vulnerable to the effects of COVID-19. The Vulnerable Communities Map intends to use publicly available data to identify vulnerable communities and support the government in their response.

To do this effectively, the map needs to showcase:

  1. Demographics: number of people by ward, population density by ward, level of formality by ward, income-level by ward
  2. Health vulnerability: Age by ward, HIV prevalence by municipality and/or district, TB prevalence, cardiovascular disease prevalence, diabetes prevalence
  3. Mobility: Linkages between communities
  4. Social vulnerability: Poverty by local municipality (using the South African Multi-Dimensional Poverty Index)
  5. Access to health care: Average distance to the nearest health facility, number of hospital beds

See this sheet for the current list of data sources

Project timeframe

Due to the urgency of the crisis, a beta version should ideally be ready by 18 March 2020.

It will then be presented for input to the CEO of the National Health Laboratory Service, the custodian of the National Institute for Communicable Diseases. It will also be presented to the SDG Hub’s partners in The Presidency.

After this consultation, an updated version should be ready by 23 March 2020.
