On average each respondent has 9.4 radiographers, sonographers and/or nuclear medicine technologists (headcount) carrying out advanced practice and 0.2 carrying out consultant-level practice.

As a rough approximation, we can extrapolate the numbers to give an estimate for the total number of radiographers, sonographers and/or nuclear medicine technologists in advanced or consultant practice in the UK. The average band 5 and above headcount of respondents who answered this section of the census is 66.6. There were approximately 26,000 diagnostic radiographers registered with the HCPC as of 2 September 2014. Extrapolating the average number in advanced/consultant practice per respondent, gives an estimate of a total of 3,662 in advanced practice and 86 in consultant practice in the UK. (This is a rough estimate as not all the band 5 and above health professionals captured by this census will be registered as radiographers with the HCPC.)
