按照奧美協議，澳洲公民到美國工作必須申請E3簽證。以下是E3簽證的統計數據。
Since the introduction of the E-3 visas, between 2000-3000 E3 visas have been issued by US consulates to Australian professionals every year; in addition to this, E3R visas are issued to the returning Australian professionals whose original visas had expired. The numbers are as follows: four new visa in Fiscal Year 2005; 1,918 new visas in FY 2006; 2,572 new and 6 returning in FY 2007; 2,961 new and 1,568 returning in FY 2008; and 2,191 new and 1,421 returning in FY 2009. In addition to this, 1,000 to 1,500 E3D visas are issued annually to these professionals' dependents.
。。。 9,294 admissions were recorded in U.S. Fiscal Year 2007 (October 2006 through September 2007).[6]
按樓主提供的表格，大概有5-8千美國公民在澳洲工作，誰能說說2個國家的人口分別是多少？？
