Operationalising 'sexual orientation' in routine data collection and equality monitoring in the UK

New legal provisions and regulatory practices in the UK have afforded protection against discrimination for sexual orientation minorities and conferred rights similar to those of heterosexually partnered couples. In addition, sexual orientation has been recognised as one of the main equality strands in new equality legislation and equality governance. Government departments and statutory and other organisations now face the need to collect equal opportunities and other data on these groups to monitor compliance. However, there has been little track record in the UK of collecting data on this dimension, resulting in issues of definition, categorisation, sample size and potential measurement error having to be addressed from a negligible evidence base. Limited survey data indicate significant problems relating to item non-response and misreporting, reflecting wider concerns about the sensitivity of the data and disclosure. Given that sexual orientation is on track to be mainstreamed in the context of workforce recruitment and service delivery, a strategy across government and other sectors is needed to pool expertise and establish a shared evidence base and stock of good practice.
