Why does the sum of the ethnic breakdown percentages not add up to 100%?

  • Updated

The genetic similarity of each ethnic group is calculated precisely down to 6 decimal places. The value is then truncated to 1 decimal place. For example, if the actual result is 95.456789%, the value shown in the report is 95.4%. Due to the occurrence of marginal difference, the sum of all ethnic breakdown percentages may not be summed up to 100%.
In other words, the sum of all actual values are 100%, but for the sake of better readability, the values shown in the report are truncated and could seem not to be summed up to 100%.
