The interdiction statistics are usually updated every business day in the morning. Flow data is updated when we get new numbers each month for the previous one. There may be periods of time when the interdictions page may not be updated for several days due to the availability of office personnel. We will try to post on the page when we know these delays will occur. Numbers can change following a migrant interdiction, especially with large boatloads where it may be hard to get an accurate number.
Numbers can also change when additional personal data is discovered.
For example, a boat may be interdicted with 20 Dominican migrants onboard. It may be found out later that 5 were Ecuadorian which would change both the Ecuadorian count and Dominican count. There may also be a possibility that interdictions in succession could cause confusion. For example a group of four and three from two separate boats in the morning may be confused with a group of seven interdicted in the afternoon.
