When did it start?

Hi. Suppose a new index is initiated, and I would like to know about the first reading of it. I know the verb "go back" can fit here, but I am not sure how to use it. Any ideas?

Could you give a bit more explanation? I'm afraid I don't understand what you are referring to, or what you want to say about it using "go back".

Sure. If for example the first period this index refers to is January 2000, I wonder if I could ask something like: "How long does the new index go back?".

That doesn't sound quite right. You could perhaps say "How far back does the new index go?"

However, I am still not sure exactly what kind of "index" you are referring to.

Thank you GPY. A new index (like consumer price index) which shows commercial real estate prices in the UK will be soon available. And I wonder how could I ask the relevant persons (at the company supervising the index) how long does their index go back.. So your suggestion seems to be appropriate: "How far back does the new index go?".. Thank you.
