讨论一句句子

astina

在看Neither Here Nor There,忽然对一句话的意思产生了疑惑，跟大家讨论一下

原句是这样的

I had expected Hamburg to be grimmer, a sort of German Liverpool, full of crumbling overpasses and vacant lots - I already knew that it had the highest unemployment rate in Germany, over 12 percent, half as high again as the national average, so I expected the worst - but Hamburg proved to be anything but struggling, at least on the surface.

我对highlight出来的这个half有疑惑。汉堡的失业率是全国最高的，高达12%，是德国平均失业率的一半？这个不是矛盾吗？是不是应该twice as high as?

是我理解错了？

它的一半已经是全国平均

"half as high again as the national average"
这个again作何解释？

楼上问的好！有同样疑问。

不知是否表惊叹，有‘竟然’‘已然’之意？
