This resource contains the population weighted percentage of Public schools on holiday across GB and for each Local Authority as well as the population multipliers given to each Local Authority. This dataset currently does not include private schools as they manage their holidays separately from the Local Authorities. The start date for each year is the first date for which any GB local authority is on its summer holiday for the first year and the end date is the final date for which any GB local authority is on its holiday before the summer holiday of the second year. Any gap between years is has no public school holidays during it. This data is used as an input into our demand models.
