The people layer, which this page refuses to count
Organizations can be counted exactly. People in roles cannot, and this is where most market maps quietly start estimating. No public register lists hospice staff by job title, and the commercial databases that appear to do it are matching on text rather than on fact: a control check run while building this page returned more than two thousand scuba instructors, pastry chefs and zookeepers apparently working at US hospice organizations. So the roles named against each row above are the structure of the decision, established from how these organizations are actually run. They are not a counted population, and any supplier who hands you a precise headcount for a role in this market has estimated it.
The seats that matter: owner or executive director, director of nursing or clinical services, the hospice medical director, finance, quality and compliance, and in multi site groups a regional operations lead.
