GGR252H1 Lecture Notes - Lecture 3: Distance Decay, Census Tract
Document Summary
Lecture three - spatial concepts and the value of geographical perspective. Sometimes built on narrow roads for max. exposure. Measured with cma (conesus metropolitan area) used with a number of census tract which gives a variable to measure from such as social economic information like education and employment position. Constantly have to update because of changing age and market target changes with it. For clubs: less effort (finding right market) for more return. But ecological fallacy, the assumption made of inhabitants can be massively disadvantageous. Dot which represent the destination (larger = size) and lines represent the origin: less cluster and closer pattern: short lines, sensitive to distance, Note: cultural difference because mennonites buy what they need and greater distance result in greater cost. Rationalization: closing down and expanding locations (compare the implications) Hospitals whether or close down specialized or general: distance decay, disincentive nature of distance, range, gravity model, diffusion.
