The interaction data at OA level

• Only one table available
• SMS: Age by sex
• SWS / STS: Mode of travel
• Data are affected by Small Cell Adjustment
• SCAM applied to Scottish data
• No OA level SWS for Northern Ireland

Notes:

Shows the table frameworks available for SMS / SWS / STS

Note the problems introduced by SCAM. The graph shows frequency of observed flow *totals* in the OA level SMS. These are dominated by multiples of 3 because of SCAM in England, Wales and Northern Ireland.
