The UK Parliament hires you and your colleagues to deliver a report that will enlighten the Parliament about the effect of labour market policies targeting single mothers. Prepare the report by answering the following questions.

To inform the parliament about the labour market status of women in the UK, you download some data from the Office for National Statistics (ONS). You prepare the following table, but you forget to label the variables. The members of the parliament want to know:
