What percentage increase do you feel is required for surge to be a reasonable definition. A 35% increase feels surge-y me.
The council planted a new tree on my road, trees surged in population from 1 to 2 yesterday
That’s why we’re talking about relative percentages.
In your example we would need to know how many trees existed on your road/city before. If there were less than 3 or 4 trees in your city before this, saying there was a surge is likely fine.
I gave you that information, I said “from 1 to 2” and added context of “a tree” (singular)
My terribly made point is that although technically correct when talking about relative increase it’s dumb as fuck to say trees “surged in population” after adding just one more on one street. It’s a drop on the ocean.
I feel like the term surge respects the final total relative to what its maximum could be as well as the relative increase. But obviously language is regional and up for interpretation
It’s not just a percentage thing. 1 person yesterday to 2 people today is a 100% increase. Not much of a surge, at least in terms of news worthiness. Going from 6% to 10% sounds more news worthy than going from 1% to 2% despite the latter being a much larger percentage increase.
