I was told that native speakers sometimes use above with ages. An example could be that anyone above the age of 18 is allowed to participate.
Therefore, I can use "above that" in my sentence and it would be short for "above that age". I was also told that I could use "beyond that". Is this true?
I also want to know if I can use "from there" to refer to the 30-39 age bracket.
Support dropped to the lowest level in the 30-39 age bracket, at 30%. Above that/beyond that/from there, support rose only slightly to 40% for the over-49s.
