4. The Housing Statistics for Scotland Quarterly Update as at September would usually include an update on all-sector new house building starts and completions to end March in the same year, with more recent figures on social sector new builds to end June. However due to the impact of COVID-19 on the provision of new housebuilding data by some local authorities to the usual timescales, this has slowed the timing of the data collection process over this period.
6. Note that the way in which we calculate total affordable housing supply figures for Northern Ireland was revised in the Housing Statistics Quarterly Update for December 2020 compared to previous publications. This has increased the level of the Northern Ireland total affordable housing supply figures compared to the figures previously published by an average of 25% across the period 2010/11 to 2018/19.
