The projected number of households in England is expected to grow to 24.3m by 2021.
The latest Government forecast means England will need an extra 2.2m homes.
This is nearly 25,000 homes a year lower than previous estimates, but still equates to building more than 221,000 homes a year.
The target is unobtainable at current building rates, which are running at half the required output levels.
Couple households are projected to grow by around 87,000 a year, equating to around 40% of the total demand over the period.
Two-thirds (67%) of the increase in households between 2011 and 2021 is projected for households without any dependent children.
During this period, the number of households is projected to grow between 5% and 10% in nearly half of all local authority districts in England.
