    Estimated total size of haplogroups

    At the turns of the 20th and 21st centuries, there were slightly over 6 billion humans in the world.

    Thus there were ca. 3,000,000,000 males. How many of them carried each of Y-DNA haplogroups?

    Any ideas, in terms of percentages and in terms of absolute numbers ???

    This thread is intended as a global Y-DNA census (we can also discuss historical and prehistoric Y-DNA demographics).

    For example - how numerous (relative to the total number of humans) was each haplogroup in 1500 AD, 3000 BC, etc.

    I like the idea of this. The problem will be that it won't be a true census. If we simply take each nation and multiply frequencies of haplotypes from studies (or aggregates of studies such as those at Eupedia or Wikipedia), we will be underestimating all the "rarer" ones.

    Why? Because much of the data is based on older studies with limited SNP panels. European studies for example rarely checked for locally "exotic" types like A, C, F, H, L, Q, T, etc. European researchers were typically looking for E, G, I, J, N, and R, so that's what they found.

    Even if these other types are a small minority, when you add this effect across the whole world, you will end up with a degree of database skew caused by ascertainment bias.

    MfA - so apparently over 3/4 of all male humans living today are descended from F ???

    These are age estimates from YFull: http://s32.postimg.org/k8goin551/YDNA_Tree.png
