The UK's Office for National Statistics expects the quality of its future Labour Force Survey data to be temporarily affected by an operational issue in May and early June, beginning from its next labor market release in July.
The statistical office said Friday an operational systems error resulted in an over-allocation of telephone interviewers' time to another survey, which impacted the response levels for the labor force survey between May 3 and June 10. Some residual effects were also found to have continued until June 17.
The ONS noted that the issue is now resolved and that it has taken steps to prevent it from happening again.
