Wave 1 files
I am analysing data from Wave 1 of Understanding Society (SN6614). There is a file called a_egoalt which defines the relationships between different members of the household; there is another file called a_child with some data about children. However, there are 174 cases in the a_child file who are not included in the a_egoalt file, which means I cannot identify their parents.
Do you know if there is a reason why these cases are not in the file?
