Comparing Economic Systems using Locus Maps

Locus Maps are FIS-based visualizations that show the number of companies per functional role in a geographically defined area. Locus Maps enable users to identify the commercial composition of a geographic area and compare it to other geographic areas.

At the heart of the Locus Model is the notion of “functional locations” for economic activities. Locus describes businesses by identifying their role (or functional location) in the economy and describing it using a constructed, standardized language derived from the Locus Model. In this language, each business function is identified by an activity, like transportation (“1.2” in the language), and the object of that activity, like information (“C”). When put together, we get the sentence “1.2 C” or “transports information,” a sentence that could describe the postal service or an internet service provider. We call this sentence a locus, because it functionally locates a business within the broader economic universe. Each locus represents a functional location.

Locus Maps are visual representations of loci for a defined geographic area. The axes are the activities and output resources from the Locus language, so each box on the grid contains businesses that are functionally similar to each other — each box contains businesses with the same locus, or functional location. Because the Locus language is comprehensive of all economic activity, every participant in an economy has a locus and can be located on a Locus Map.

In the current iteration of the Locus Map, boxes are sized based on the number of businesses with the given locus. A bigger box for a given functional location indicates a more prevalent economic function in the selected universe. In future iterations, we plan to incorporate other sizing parameters, like revenue or number of employees, to allow for comparisons across multiple dimensions. Because the Locus language can also be used to describe jobs, we plan to incorporate employment data into the app to allow users to identify and compare labor distributions between geographic areas.

By providing visual representations of loci, maps.locus allows users to identify different typologies of economic communities. While economic activity isn’t distributed evenly across sub-regions, it does tend to cluster in identifiable ways. Because the Maps are standardized, it’s easy to compare one geographic area (a zip code, a city, or a metropolitan area) to another and identify differences in the composition of businesses. Some zip codes are central business districts, some manufacturing centers, and some residential neighborhoods. Below, we’ll walk you through a few example Maps to show how best to utilize maps.locus to explore economic compositions.
