在模式的外围的是过渡时期的国家，与此同时，围绕在中心周围的环形是仍然拒绝加入欧洲经济货币联盟的欧盟国家，或者是像罗马尼亚和保加利亚这样尚未满足所有条件的国家，或者是最终的西巴尔干半岛国家和土耳其。
The outer circles are the transition countries, while the rings around the center would be EU countries that still refuse to join the EMU, or do not yet fulfill all the conditions, like Romania and Bulgaria, or eventually the western Balkan countries and Turkey.
