Original consultation
Consultation description
We’re consulting users of the ‘Monthly statistics of building materials and components’ data on deliveries of bricks, blocks, ready-mixed concrete and sand and gravel. It gives users an opportunity to help say how seasonal adjustment should be implemented, including:
- scope
- presentation of statistics
- revision policies
Seasonal adjustment is widely used in official statistics. It aids data interpretation by removing effects associated with the time of the year or arrangement of the calendar from the data series.
