在哪裡搜查數據?
Due to the scarcity of centralised data on immigration detention, we looked for data that exists under multiple government departments. Furthermore, the limited data on detention makes comparative data, such as with prison institutions, increasingly relevant.
查找數據有何難處?
查找有關羈留人數的數據有難度,部份原因是因為羈留人士很可能分散於由不同部門管理的多個處所。
另一個難處就是不同時段的數據集不一定採用相同的量度準則,使得將各個數據集合併起來以涵蓋更長的時段的做法不可行。
量度與單位
在數據集裡所遇見的量度包括:
- 每年羈留人數,
- 每日平均羈留人數,及
- a snapshot of the population at a given date (ex. end of the month, end of the year)
每年羈留人數可以闡明一個羈留設施人數流動的幅度,而每日平均羈留人數有助於了解羈留設施接近容量飽和的年份。然而,因為每日平均羈留人數一定不會超出設施的總容量,進行各個羈留設施之間更廣泛比較仍然有相當的限制。
