Census data is also used by ONS to revise the boundaries for Output areas (OAs) – an geographical area of 100 – 625 people (40 – 250 households). OAs are the smallest geographical area Census data is available in and are grouped to create LSOAs (Lower level super output areas) and MSOAs (Middle layer super output areas). Information on how the OAs in Calderdale have changed are available on Census 2021 data set.
