Household projections for England are now the responsibility of ONS. Latest figures are 2016 Based. It is important to note that the methodology is different to the last set produced by CLG and results in much lower household numbers. Wales, Scotland and Northern Ireland all produce their own sets of Household projections.
Previous sets – CLG Household Projections
CLG published the 2014 based Sub-national Household Projections on 12th July, 2016. For England the projections are 4,000 households per year higher than in the 2012 based set (214,000 pa vs 210,000) with Average Household Size falling from 2.35 to 2.21 – the same as in the 2012 based set. Tables and documentation can be found here 2014 Based CLG Household Projections.
A comparison by Local Authority of 2012 and 2014 based Household Projections are available here Comparison SNHP 2012 vs 2014

Projection Model Software
Currently the main product used by Local Authorities is POPGROUP which is used in both England and Wales. Some Local Authorities have their own models e.g. Hampshire County Council and the Greater London Authority. I have used POPGROUP for 10 years and I was a member of the Steering Committee.
If you want projections running, the software is very good value to Local Authorities and is very quick to get up and running. There is an annual fee for support and updates. Once set up, it is straight forward to develop alternative scenanios.
- If you want advice or guidance on scenario building or any of the inputs then I can help with that.
- POPGROUP training is also available from Ludi Simpson who tutors the Annual Manchester POPGROUP day courses in June. He can also train on-site or to regional groups on request at a negotiated cost.
