Red Lobster also defines its trade areas based on market size and population density. Here are its seven density classes:

DENSITY CLASS DESCRIPTION HOUSEHOLDS PER SQ. MILE 1 Super Urban 8,000+

2 Urban 4,000−7,999 3 Light Urban 2,000−3,999 4 First Tier Suburban 1,000−1,999 5 Second Tier Suburban 600−999 6 Exurban/Small 100−599 7 Rural 0−99 Note: Density classes are based on the households and land area within 3 miles of the geography

(e.g., census tract) using population-weighted centroids.

The majority (92%) of the Red Lobster restaurants fall into three of these classes. Which three classes do you think the chain has the most restaurants in? Why? Lop9
