How do I know this fact? Well it's because I have taken a look at the Bone Marrow Donors Worldwide Website and this is the figure that they publish as being the current up to date total.
I noticed that the UK contribution to the total (per capita) is very impressive, but some other countries , for whatever reason ,seem to be lagging a little behind when sourcing either Bone Marrow Donors or Cord Blood Donations.
14,843,311 is Good!,but with a little more encouragement that figure could be a lot higher in a world population of 6,884,909,953 souls!
