The average population of the EU-15 is about 25 million, many more than the six million in the average US state, which more closely resembles the average population of EU regions, such as Bavaria, Wallonia, Île-de-France and the Canary Islands. So perhaps it is more useful to compare the 50 US states with the EU’s 72 regions.
欧盟15国的平均人口大约是2500万，比美国各州的平均人口600万要大得多，后者与欧盟地区，比如巴伐利亚、瓦隆区、法国和加纳利群岛的平均人口差不多。所以将美国的50个州与欧盟的72地区进行比较更有用。
