You should delete it. But you'd have to use the present perfect:
The number of shoppers has plunged by up to 23 per cent since then.

Many thanks

"Since then on" is not an English phrase that I've ever come across.

" The number of shoppers has plunged by up to 23 percent since then. "

-- "Since then on" doesn't make much sense at the end of that sentence.

No, it's wrong. It should read:

The number of shoppers plunged by up to 23 per cent from then on. Or:The number of shoppers has plunged by up to 23 per cent since then.

It's still a lttle odd with the 'up to'. Either it plunged by 23% or it didn't.

ps. You are too fast for me, SlickVic.

No, it keeps plunging. Once it plunged to 23%. So it did. Other plunges were less. So it has plunged by up to 23%.
(I agree that it's probably a wrong interpretation of what happened though.)
