The following is a complete list of the major ethnic group clusters included in the Atlas, accounting for 99.6% of world population (haplogroup details by cluster). Each major people cluster is composed of numerous sub-clusters, such as British, Irish, Scottish, etc. within the major group called Anglo-Celt. The complete list of sub-groups for each major cluster is available here, by selecting a 'people cluster' and then the 'submit' button. The complete data set used in the Atlas is available for download in various formats.
