Here's a great benchmarking study on bicycling and commuting trends around the US. St. Louis is a participant in the study.
However we are listed in a group of "Other City" because this study counts only the city population (300,000+) in the national rankings.
Here is the study: https://www.nh.gov/dot/programs/bikeped/documents/2016benchmarkingreport_web.pd.pdf
There is great information here and we can see how we stack up.
Generally we are near the bottom in many categories country-wide and a little better as a city.
