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.

Lots of legitimate reasons for not donating, including those mentioned in the replies. And I have much respect for those of you who want to donate but can't or tried to donate and got sick, so can't.

I've been donating for decades and have been turned away twice. Both times turned out to be blessings in disguise.

The first time it was because my hemoglobin (tied to iron in the blood) was too low. Turned out I had an iron deficiency that was causing other problems and put me on notice that I had to address it.

The second time was because my blood pressure was too high. Found out I had high blood pressure which could shorten my life if I didn't address it with medication. It's at a safe level now.
