2) Everyone on the Homechoice Register (HCR) needs a house.
A) No not everyone, some households do but a substantial percentage do not.
B) Most households on the HCR are actually living in a dwelling already.
3) The numbers on the HCR who DO need a house equals the number of houses that must be built.
A) No really. Yes in some cases – where there is an extra household within an existing household (concealed is the term used), a new dwelling is needed. But in most cases when a household moves into a dwelling (as someone else vacates a property), then their accommodation is available for someone else! So there is no need to build lots of extra ones.
The HCR is used to make people feel uncomfortable about opposing new housing but it vastly over estimates the numbers of actual new dwellings required.
