How Population Finder Reveals Ethnic Ancestry

Population Finder is a report included with the Family Finder DNA test from Family Tree DNA. Today, this report is the single best option for measuring a person’s overall ethnic ancestry.
By comparing your DNA to that of global populations, it does what’s called a biogeographical analysis.
As part of Family Finder, it uses your autosomal DNA, which reflects the contributions of ALL your ancestors going back at least five or six generations.
Some companies market tests that claim to make finer distinctions than this. But their reports are based on such tiny population samples that the results are mostly wishful thinking.
Population Finder is the most scientifically credible ethnic DNA test available today.
Reference Populations
This report compares your DNA to more than 60 reference populations that have been accepted through scientific studies. These populations come from the following seven continental groups:
  • Africa
  • The Americas
  • East Asia
  • Europe
  • Middle Eastern
  • Oceania
  • South Asia
The following table shows all the reference populations at the time I created this web page. Family Tree DNA adds new populations as they become scientifically accepted and your results may evolve. There is no added fee.
