* "The HTC Population Profile is a set of twelve data items collected on patients with bleeding disorders or venous thromboembolism. These patients receive care at Hemophilia Treatment Centers (HTCs) that are part of the US Hemophilia Treatment Center Network (USHTCN), a network of 141 HTCs located throughout the United States and its territories."

"This map presents the number of individuals who attended a federally supported hemophilia treatment center (HTC) from 1/1/2012 to 3/31/2022 and who were entered into the HTC Population Profile as of 3/31/2022. Individuals were counted only once, regardless of the number of visits made to an HTC during this period. The first 3 digits of a participant’s zip code are reported for the HTC Population Profile and are used to determine state of residence. Participants with zip codes that span more than one state are grouped into the state with more Community Counts participants."
