Child Yield Multipliers for New Developments

In September 2015, the Research Group produced a review on the child yield multipliers used to assess the education requirements of new housing developments in Cambridgeshire. The multipliers are intended as a guideline only and, in some cases, an alternative approach may be more appropriate.

The key findings from the review were:

 - No significant changes are proposed to the ‘general  multipliers’ used by the County Council to forecast the number of school-aged children in new developments where a detailed housing mix is not yet known.

 - Overall, the ‘general multipliers’ for new developments will remain at 25-35 primary children per 100 dwellings and 18-25 secondary pupils per 100 dwellings. 

 - It is proposed to increase the general multiplier for the pre-school population to 20-30 children aged 0-3 per 100 dwellings.

 - Where a detailed housing mix is known, changes to the detailed multipliers for social rented housing and market housing are proposed. These changes reduce the number of children expected in market properties but increase the number in social-rented properties.

The full review which lays out the agreed multipliers for the County Council can be found below.  This was reviewed and agreed by a full council committee on 8 September 2015 and the multipliers were implemented from that date.
