  • Which group is most/best represented at FTDNA?

    Hi!

    Lately I've been wondering which ethnic group or nationality is most represented in the Family Tree DNA database. I have the most common haplogroup in Europe, but my results are lacking. I know lot of Americans with European origins test with FTDNA, so I'm a bit confused by that. I also have the most common maternal haplogroup in Europe and the lack of results disappointed me too.
    I have a feeling the Ashkenazim test via FTDNA a lot but this could be pure speculation. Anyone have any guesses on which ethnic groups are best represented in the database? I hope my question makes sense.

    Do you mean:
    - In absolute numbers, or
    - Proportional to current population, or
    - Proportional to pre-colonial (1500 A.D.) population?

    My own guesses:

    In absolute numbers, the British Isles are unquestionably the most heavily represented in FTDNA's database.

    Proportional to pre-1500AD population, Ashkenazi Jews and the British Isles are best represented, mostly because these two groups have undergone the most rapid demographic expansions over the past 500 years.

    Proportional to current population, FTDNA's database reflects Americans most heavily; and among them, Ashkenazi Jews and descendants of pre-Revolutionary colonists (therefore mostly British Isles) are probably best represented, IMHO.

    But this should not discourage anyone from testing. Instead, you can spark interest in testing among members of your ethnic group!

      If you do not have very many matches that can be sort of exciting in a way. You may potentially be able to be a pioneer of defining your own little corner of the Y-DNA phylogenetic tree.

        Finns are especially well tested at FTDNA. Very soon Finland DNA Project will have one participant of every thousand people currently living in Finland. Of course considerable amount of them are Finnish Americans, but still it is quite a feature.

        The main reason may be that Finnish genealogy tends to be quite productive. (I have found about 1000 my ancestors this far, and my roots are not anything special.)

            Excellent question Schnook.

            It would be great if FTDNA would publish some hard statistics on the makeup of the database.
            We can only hope that FTDNA read this thread and act on it.

            IANA Statistician, but I figure...
            • The sample size is very small compared to the world population.
            • The sample is very biased as it represents only the individuals that choose to purchase dna testing.

            The sample bias would mirror the market penetration though advertising and word of mouth promotion for each regional/cultural group. And one might guess that the market penetration would be highest in the US, with other countries following in some order. Cultural proclivities toward an interest in 'genealogy' would play some part.

            It would be nice if FTDNA could supply some hard stats.
            A breakdown by country would be handy.
            A breakdown by test type might be of interest (but is probably company confidential).
            A breakdown by haplogroup would be invaluable to group administrators!

            (they say the squeaky wheel gets the grease)

              Wonderful!
              If only our surname project could boast such penetration.
              We have about 150 members, but this is minute compared with the total world population of that surname.

                Thanks for everybody's response!

                Now I'm thinking how some groups are severely under represented in the database. I believe this kind of testing is illegal in France, and it's banned in some US states. So French people are under-represented, as are people from Maryland. (Not that Maryland is a nationality but you catch my drift) (And I THINK it's Maryland where this stuff is illegal)

                Especially interested in that surname website, thanks flanged! I'm trying to figure out more information about my surname - it's English apparently but it's also found in some Ashkenazim so I'm really intrigued by what kind of people have the name. Especially since I'm trying to trace Jewish ancestry in my family. So thanks for sharing.

                  Depends on GDP and English language?

                  A breakdown by country is probably company confidential, too (for the same reasons).

                      I take your point especially since Irish-Americans love to trace their roots back to Ireland.

                          23andMe has some issues in Maryland and in the state of New York, and that is clearly explained in their FAQ. It does not look like that in any way applies to testing with FTDNA .

                          On the other hand, France looks like a special case. I wonder whether anybody can explain their situation as far as genealogical testing in plain English

                          23andMe claims that it is shipping to France. Also according to Does Family Tree DNA ship internationally? http://www.familytreedna.com/learn/f...-destinations/
                          There are some countries where shipping requires special processing. These are Brazil, Japan, Mexico, Russia, and Saudi Arabia. There are two countries whose customs restrictions prevent us from shipping to them. They are Sudan and Iran.
                          Anyone?

                            Did some analysis of global surname frequency for my project. You may be interested to do your own.
                            I have X'd out the surname for confidentiality.
                            Interesting to note that the frequency for this celtic surname is higher in some colonial countries than the UK.
                            Excuse the crappy layout below.

                            Estimate of global population of the Xxxxx surname, using...
                            Population per country - data from http://en.wikipedia.org/wiki/List_of..._by_population.
                            Top 10 Xxxxx frequency by country - data from http://worldnames.publicprofiler.org.
                            Xxxxx frequency for the rest of the world (ie, background frequency) is guestimated at 0.5 per million.
