Catalonia has 34 blood donors per thousand of population, almost double the European average
Every day in every hospital in the world blood is needed. The only way to get it is from donations, since blood cannot be created artificially. Each altruist action may serve to help three different patients. In Catalonia, for the system to work optimally 1,000 donations a day would be needed but the average donation figure is lower. Everyone can donate if they weigh over 50kg, since a donation is 450ml of blood and a minimum weight is required. Men can do it four times a year and women three times. There are now various mobile units that travel throughout Catalonia to make donating more accessible to donors.
