I.    Radiographers Covered

1.1   Diagnostic Radiographers

1.1.1  The radiographers covered in the 2011 HMS includes both diagnostic and therapeutic radiographers.  Diagnostic radiographers refer to those radiographers (Category D) registered with the Radiographers Board of Hong Kong under the Supplementary Medical Professions Ordinance (Chapter 359) as at the survey reference date - 31.3.2011.

1.1.2  The number of diagnostic radiographers covered was 1 473.

1.1.3  Of the 1 473 diagnostic radiographers covered, 707 had responded to the survey, giving an overall response rate of 48.0%. Among the respondents, 670 were economically active*† (active) in the local diagnostic radiography profession as at 31.3.2011 and 37 reported to be economically inactive*‡ (inactive) in the local diagnostic radiography profession (Chart A).

*   In the survey, the criteria used in defining economically active / inactive followed those recommended by the International Labour Organization, which are also being used by the Census and Statistics Department in Hong Kong.

†  “Economically active” diagnostic radiographers comprised all “employed” and “unemployed” diagnostic radiographers. The “employed” diagnostic radiographers referred to those diagnostic radiographers practising in the diagnostic radiography profession in Hong Kong during the survey period, while “unemployed” diagnostic radiographers referred to those diagnostic radiographers who (a) were not practising in the local diagnostic radiography profession during the survey period; (b) had been available for work during the seven days before the survey; and (c) had sought work in the diagnostic radiography profession during the 30 days before the survey.

‡   “Economically inactive” diagnostic radiographers comprised the diagnostic radiographers who were not practising in the diagnostic radiography profession in Hong Kong during the survey period, excluding those who had been on leave during the survey period and who were “economically active” but “unemployed”.
　

1.1.4  Of the 670 active diagnostic radiographers enumerated, 665 were practising in the local diagnostic radiography profession, two were seeking jobs, two were expecting to return to original jobs in the local diagnostic radiography profession and one was having temporary sickness during the 30 days before the survey period.  The survey results presented in paragraph 1.1.6 below were based on the 665 responding diagnostic radiographers who were practising in the local diagnostic radiography profession as at 31.3.2011.  As some information was missing from certain questionnaires, percentages presented below may not add up to 100%.

1.1.5  Of the 37 inactive diagnostic radiographers, six reported practising overseas and 31 reported not seeking job in the local diagnostic radiography profession during the 30 days before the survey (Chart A). Among the 31 inactive diagnostic radiographers who reported not seeking job, the main reasons reported for not seeking jobs included: 17 (54.8%) were working in other professions, five (16.1%) were engaged in household duties and four (12.9%) were retired, etc.

II.    Trend Analysis

Comparison of findings of the 2011 HMS with those surveys before 2004 should be cautious as the survey methodology and reference date had been changed.  With the enactment of the Radiographers (Registration and Disciplinary Procedure) Regulation (Chapter 359H), registration of the profession of radiographers commenced on 1 July 1995 while disciplinary control of the profession was effective on 1 November 1996, it is mandatory for a person practising diagnostic radiography / therapeutic radiography in Hong Kong to hold a valid practising certificate.
