Overseas arrivals and departures, Australia 1975-1981: six-monthly detailed tables: File b78

Statistics of overseas arrivals in, and departures from, Australia are collected by means of the Incoming and Outgoing Passenger cards completed by all travellers. As well as being used for statistical purposes, the information collected is used by the Department of Immigration and Ethnic Affairs for administrative purposes. Data is made available on a six-monthly basis, in matrix format, from the beginning of 1975 to the end of 1981, and relates to the number of movements in a specified time, rather than the number of travellers (i.e. the multiple movements of individual persons within the time period are each counted separately). Information collected includes category of travel, duration of stay, country of birth, citizenship, dis/embarkation, as well as age, marital status and sex, and occupation.

澳大利亚出入境旅客统计数据由全体旅客填写的《出入境旅客卡》（Incoming and Outgoing Passenger Cards）采集得到。所采集的信息除用于统计工作外，同时供移民与民族事务部（Department of Immigration and Ethnic Affairs）开展行政工作使用。该数据集的发布周期为每半年一次，采用矩阵格式（matrix format），时间跨度为1975年初至1981年底；其统计维度为特定时段内的出行次数，而非旅客人数（即同一旅客在该时段内的多次出行将被分别计数）。采集的信息涵盖出行类别、停留时长、出生国家、公民身份、出入境口岸，以及年龄、婚姻状况、性别与职业。
