Hertfordshire Housing Target

I am grateful to the Minister, who actually responded to my points with some purported facts rather than simply ignoring them. That is the first time that that has happened. The Minister said that the population increase over the planning period—about 20 years for Hertfordshire—was expected to be about 30,000 people, on top of a million. If they live in an average household of two and a bit people, that increase will represent 12,000 or 15,000 extra houses. Is the Minister saying that of the proposed 90,000 extra houses, only 12,000 or 15,000 are for an increase in population and that all the rest are for other reasons? If that is so, it is the first time that we have ever been told. It is an interesting fact, but I should like it to be substantiated.
