I'm not sure whether the plural form below would be correct.
Many public officials are seeking out ways to increase the populations of their towns.
At first, I thought that it would be better to use the plural form because it refers to the people that live in various towns.
However, if I consider the situation of people living in each town(there's no one who has his/her address here and there), I think it might be proper to use the singular form.
Could you tell me which form would be grammatically right?
Thank you for reading. ;)
