businesses and government services?
(6)
2.2. Discuss one advantage and one disadvantage of using GPS technology in

Question 3
3.1. What are two key preparatory steps required before conducting field-based
geodemographic data collection?
(4)
3.2. Describe three spatial factors that influence retail location strategy.
(6)
3.3. Scenario:
A retail pharmacy chain in Namibia wants to expand its services beyond Windhoek
into smaller towns and rural areas. The company has access to demographic and
health data, including poverty rates, education levels, accessto services, and mobile
coverage. It wants to use a geodemographic approach to:
• Select optimal store locations,
• Understand the needs of different communities, and
• Support the Ministry of Health and Social Services (MoHSS) by improving
medicine accessibility.
As a geodemographic consultant, you are asked to prepare a brief strategy using
geodemographic principles.
