Customer sentiment by city

How this is calculated. For each city we sample well-known businesses (restaurants, hotels, hospitals, supermarkets) from public Google data. The sentiment score is the share of positive review excerpts (neutral counts half), read by our own text rules from the reviews Google returns. The Google rating is the average across the sampled businesses, weighted by how many ratings each has. This is not CSAT: no survey answers are involved, and each business contributes at most 5 review excerpts, so treat it as an indicator, not a ranking of cities.
