1. Please write a brief (few sentence) description of an interesting cluster pattern for bookstore locations within Cambridge.
 
 
   
   
   
 

2. Create and attach a labeled and annotated map supporting your description in Question 1.
 

3. How many children aged-5-and-under do you estimate were living within 2/3 mile of Ames Street based on the 2000 census?
 
 
 

4. Make a map showing Ames Street and the 2/3 mile buffer on top of a block group thematic map of children aged-5-and-under. Instead of mapping the 'number of children,' you will want to map the density of children in the original block groups. Do you see why? Label one of the larger block groups that partially overlaps your buffer with the percentage of the block group that is within 2/3 miles of Ames Street.
 
 

5. Briefly describe the difference between the output themes (that is, the shapefiles) produced by using the union and intersect operations to combine two polygon themes.

Both maps and the answer sheet should be submitted via Stellar. Your maps may either be in grayscale or, preferably, in color; just make sure they are readable.
