Where the data comes from
Counted from the public agent directories of 8 brokerage brands with agents in St. Louis. Independent brokerages outside those networks are not counted, so this is a ranking among the networks we can see, not a census of every licensee in the city. Full method on the national page.
The count comes from a per-agent file kept by usrealtorlist.com (the Missouri realtor email list); an agent is included only with a published, current email, which is what keeps the figure to working agents.
