这句话中的114%是说10年的增长率还是1年?解释一下
Altogether, the US population rose in the 1970s by 23.2 million people -- numerically the third-largest growth ever recorded in a single decade. Even so, that gain adds up to only 11.4 percent, lowest in American annual records except for the Depression years.

Answer 1

首先,这里应该是11.4%
其次,应该是1年的增长
理由:1.前述的是说在10年里第三大的年增长
2.也可以从后面的annual（年度的）可以看出
