This document is an invitation from someone named Richard Dunks to discuss using open source tools like PostgreSQL, PostGIS, QGIS, Pandas, and OpenStreetMaps to analyze Census data for sales managers. The document provides example differences in demographic data like gender, race, housing occupancy between various Manhattan locations and all of Manhattan overall. While acknowledging it's technically a hack, Richard Dunks offers to discuss how these tools can be used to access Census data and analyze it. He provides his contact details to discuss further.
