1.3. Economic activity - descriptions
Locate a document or various documents that provide sector descriptions for your location. The key sectors that make up the bulk of economic activity should be described. This document does not need to be exclusively dedicated to describing these sectors, but it must provide an insightful breakdown of the local economy. Note that this is not about data (numbers), but we are instead looking for a descriptive document.
Economic reports of the city or area, or more general "city profile" reports from the government may be a good place to start.
