I thank the witnesses for their work in this area. I am trying to understand the 47,754 in the unknown category, as the witnesses put it. The opening statement suggests that those living in possible informal rented dwellings or this unknown category were paying 30% less rent than households in formal rented dwellings. Is that just 30% less in overall terms, or is it comparing like with like and comparing similar types of properties and areas? Is it geographical? Is it just 30% in general?
