Should I use 'upward trend' or 'increasing trend' in this sentence?
- There has been an upward trend in expenditure over the last 36 year by 20-30%.
- There has also been the increasing trend in expenditure over the last 36 year by 20-30%.
If you are describing a graph, it’s a bit odd that the period of time is a specific figure (36 years) and the percentage increase a general spread, unless the increase is appearing in multiple entities.
I prefer ‘upward trend’ here for some reason, but you could reword in different ways.
There has been an upward trend in expenditures of 20-30% over the last 36 years.
Expenditures have tended to increase over time, so that they are currently 20-30% higher than 36 years ago.
