It includes data relating to all children who ceased to be looked after during a collection year if they were aged 16 years or older at the time of care ending.   Only the last occasion that care ceased is included.  However, there is information about the reason for the episode ceasing and a description about the suitability of their final placement.  

Within SAIL, this dataset must be linked to the primary Children Looked After census (LACW) to get child characteristics (week of birth, gender, ALF).

Other useful information 

Due to the anonymization process, not all data fields referred to in the local authority guidance are available for use by researchers.  However, this resource provides a useful starting point for understanding what is collected and the legal framework that sits behind some of the codes used. 

Aggregate data going back to 2016-17 is available on the Stats Wales website:  

There are approximately 650 – 700 records per year.   

There is some reporting of the data in the Welsh Government’s annual statistical release about children looked after by Welsh local authorities.  The latest version can be found:
