nowhere用法

請問這句子 Nowhere is there more of a population problem than in this city. 這是倒裝吧,請問這裡nowhere該怎麼看?

"Nowhere" is there more of a population problem than in this city. ="There is nowhere where" there is more of a population problem than in this city. ="There is no place where" there is more of a population problem than in this city. "沒有任何地方" 有比這個城市更嚴重的人口問題。 對,這是倒裝。 Nowhere is there A.=There isn't A anywhere.
