1. Rank-size rule is the idea that the population of a city or town will be inversely proportional to its rank in the hierarchy. #2 = ½ #3 = 1/3 #4 = ¼ #5 = 1/5

2. New York City: 8,336,697 Los Angeles Chicago Houston Philadelphia Assess validity by finding populations of these cities based on rank-size formula.

3. Los Angeles: 3,857,799

4. Chicago: 2,714,856

5. Houston: 2, 160,821

6. Philadelphia: 1,547,607

15. Threshold is the minimum market area size for a good. Range is the maximum distance a customer is willing to travel. Gravity model says optimal location is directly related to number of people in the area and inversely related to the distance people must travel to reach the service.
