I just came across the above chart from City Observatory showing the percentage of restaurants in each city that are part of a chain. (The data is taken from Yelp.) On the top is New York City, where only about 13% of restaurants in the city are a chain. And on the other end is Louisville, where more than 35% belong to a chain.

The article also observes that there appears to be a correlation between restaurants per capita and the percentage of independents. In other words, the more restaurants you have, the higher the likelihood that more of them will be independents. New York City is once again at the top with 22 restaurants per 10,000 people.

What is perhaps most interesting about this data is that Yelp ratings show a pretty clear preference for independent restaurants. Meaning that, on average, independent restaurants receive a higher rating compared to chain restaurants. At the same time, this spread seems to be widening. Here's data from 2012 to 2017:

This is maybe obvious; but it's worth reiterating. As city builders, it's good practice to encourage independent and small businesses. They are a competitive advantage. People, at least based on this Yelp data, seem to clearly like them more. So I guess Jane Jacobs was right: "The greatest asset a city can have is something that is different from every other place."
