Only 1% of people who give blood in England are black, according to the NHS. To meet demand 40,000 more black donors are needed.
The increased demand for some rare subtypes that are more common in people of black heritage means the NHS needs more black people to become blood donors.
Demand for these subtypes is growing as more people have regular transfusions to treat blood disorders such as sickle cell disease.
Subtypes are important when someone has regular transfusions as they need blood that matches their own as closely as possible.
The NHS needs people from all communities to give blood to make sure there’s the right blood available for everyone.
