Census data can be very detailed; we need use Excel spread sheet (or other similar tool) to compute the percentage of elderly population by Census Tract, and save the results in Dbase IV (.dbf) format, to be JOINed into the Shapefile attribute table of the Census Tracts in the base map.

    Excerpt: ... GEPL 4110: 5110 Geographic Information Systems Spatially Determining Netflix Target Audience in Toledo, OH Jimmy Thompson (Grad Student) Introduction Netflix was created in 1997 by Marc Randolph and Reed Hastings who were coworkers at a software company and by 1998 the website was functional (Czar, 1998). A year later the company introduced a monthly subscription plan and Netflix quickly grew to what it is today, netting $66.9 million in 2007 while employing over 1,400 people (Netflix Facts). This growth has forced video rental stores to change the way they do business by offering unlimited rentals or even offering a similar mailing service. Using the United States Postal Service, Netflix is able to ship 1.6 million DVDs daily (Netflix Facts). This study will analyze a target audience that Netflix may appeal to in Toledo, OH. The study will focus on location, convenience, median income, and age in Toledo census tracts . At the conclusion of this paper, areas of Toledo that should be targeted by Netflix adve ...
