Explanation

Descriptive analytics summarizes and describes historical or current data to show what has happened or what currently exists. Displaying population counts and crime rates per district is a straightforward description of existing facts - it answers 'What is the current state?' Prescriptive analytics recommends actions. Diagnostic analytics investigates why something happened. Predictive analytics forecasts future outcomes. Since the analyst is simply presenting population and crime rate data for visualization without forecasting or diagnosing causes, descriptive analytics is the correct technique.
