As written, you could use "rates". I would prefer a "the" before "poverty" and "rate" in the blank.
Will you please let me know what noun I can use in the following sentence?
...there's been a considerable rise in poverty ......................... in the region. (I want it to be the opposite of 'reduction'. This could be a part of a line graph showing the rate with which poverty is fluctuating, perhaps.)
Sure thing. I will use them too. Thanks a million!
You could also use nothing in the gap.
