What Percent of the Eligible Population Donates Blood?

Only 3%. That is unfortunate because it is one of the few ways an ordinary person can actually save lives. And there is always a greater need than the supply.

But please don't hate on people simply because they don't donate. Many can't because of things beyond their control. Like being below a minimum weight, having an iron deficiency, certain health conditions, exposure to certain illnesses (which can simply result from travel).

But if you can, I encourage you to do so.
