Choropleth Map of Norman Sicily's Monastic Orders


In economics, a location quotient is used to determine areas where employment in a specific industry may be over- or underrepresented. In this example, the location quotient concept is applied to the number of monastic foundations by order. The location quotients should identify concentrations of orders in Sicily's provinces. In the model, the monastic order replaces the concept of industry. For regions, the boundaries of the modern provinces are used for convenience, while the reference area is the whole of Sicily.

See the README file for more information.

All code is available via this project's GitHub repository.


Select a monastic order from the dropdown menu and with your mouse hover over the various provinces to see the concentration of a specific monastic order.

Tick the checkbox marked "Include Uncertain Data?" to include monasteries with undetermined locations or orders in the calculation of the location quotients.
