Breakdown of Unique Visitors by Last Touch Channel is Greater than Total

[Swanan_]

Hi Community,

I want to analyze my unique visitors by last touch channel over a trimester. The total seems to be 320K. But once I sum up each line I see more than the total (the sum of the 5 first lines is already greater than the total).

See screenshot below:

Thanks to this post, I understand the for marketing channel, a unique visitor can be counted in 2 differents channel. But since I'm using the "Last Touch Channel", how can it be possible?

Thanks a lot for your help.

This is due to de-duplication of visitors when showing total. A visitor may have seen more than one channel (each channel will show the visitor count). When total is calculated Analytics de-duplicates those visitors and regards him as one unique visitor.
