3.4. Scenario:
The Namibian Ministry of Health and Social Services (MoHSS) is partnering with a
private telecommunications company to promote a mobile health (mHealth) platform
that enables users to book appointments, access health tips, and receive medication
reminders. Despite its potential, the uptake of the service is low in certain areas. The
Ministry wants to use geodemographic analysis to guide where to focus awareness
campaigns and improve healthcare infrastructure.
Question:
Using the scenario above, explain the concept of geodemographics and describe how
it can be applied to both market analysis (by the telecom company) and social service
planning (by the Ministry of Health and Social Services). Support your explanation
with relevant examples.
