The methodology used to identify race in the HSCRC data files changed in 2013. Therefore, data reports in 2013 and beyond may not be comparable to data reports released in earlier years.
Data are of Maryland residents seeking care at a Maryland hospital. Data may be underreported, especially in counties contiguous to DC. |
