Driving and riding tests: extra data

The data published here is to accompany the Driving & Riding Test and Instructor Statistics releases (http://www.dft.gov.uk/statistics/series/driving-tests-and-instructors/).

Links are provided to the test centre result files (which are 'operational' statistics, rather than Official Statistics) and ethnicity data.

The ethnicity data should be used with extreme caution. The information is voluntarily provided by test candidates and over 70 per cent of candidates do not declare any ethnicity at all. The data are therefore subject to self-selection and self-reporting biases and it is likely that the figures do not accurately represent the true ethnicity breakdown of test candidates. The data are being provided for information only and are not classified as an Official Statistic.

本处发布的数据旨在伴随驾驶与骑行测试及教练员统计数据（http://www.dft.gov.uk/statistics/series/driving-tests-and-instructors/）的发布。提供链接至测试中心结果文件（这些为‘运营’统计数据，而非官方统计数据）以及民族数据。对于民族数据的运用应极为谨慎。该信息由测试候选人自愿提供，超过70%的候选人并未声明任何民族归属。因此，数据受到自我选择和自我报告偏差的影响，且这些数据很可能并不准确反映测试候选人的真实民族构成。提供这些数据仅供信息参考，且不被归类为官方统计数据。
