Survey of Public Opinion on the Age of Criminal Responsibility in Hong Kong


Summary

Between April 28 and May 8, 1999, the Department of Applied Social Studies, City University of Hong Kong conducted a random sample telephone survey on behalf of the Law Reform Commission of Hong Kong. This survey successfully interviewed 1,144 people aged 15 or above to collect their opinions on the age of criminal responsibility. Their opinions indicated that an overwhelming majority (89.4% of the population as estimated from the survey) of people preferred a minimum age of criminal responsibility at an age of 8 years or above. A minimum age of 14.4 years was the average in the population. More than a quarter (28.4%) of people supported applying the rebuttable presumption of doli incapax to persons aged either between 7 and 14 years or specified ranges preferred by respondents. It was particularly favorable for applying to persons between a raised minimum age and 14 years, according to an appreciable proportion (21.4%) of people. However, relative few (6.4%) people supported applying the rebuttable presumption of doli incapax to persons between 7 and 14 years of age. On the other hand, the rebuttable presumption of doli capax received support from a low proportion (6.9%) of people.

Significant variation in the opinions appears among people of different characteristics. The preferred minimum age of criminal responsibility varied significantly among different characteristics of people’s age and education. Agreement to the rebuttable presumption of doli capax varied significantly among different characteristics of people’s sex, age, religious faith, and education. Furthermore, support for the rebuttable presumption of doli incapax significantly varied among different levels of education and knowledge about the law of criminal responsibility. Hence, preference for a minimum age of 8 or above varied from 71.7% among people with no formal education to 94.0% among people aged between 20 and 29 years of age. Agreement to the rebuttable presumption of doli capax ranged from 4.3% among people with no formal education to 15.0% among people aged between 50 and 59 years of age. General support for the rebuttable presumption of doli incapax ranged from 20.3% of people with primary education to 38.4% among people with no formal education. All these opinions were significantly different among people of different educational levels.

Report

1.Following a pre-test of 33 interviews on April 22 and 23, 1999, a random sample telephone survey interviewed 1,144 people in Hong Kong between April 28 and May 8, 1999. This pretest and full-scale surveys drew samples of the population through the sample frame of all residential telephone number in Hong Kong. The random sampling procedure involved two steps: (1) drawing a random sample of residential telephone numbers and (2) drawing a random sample of members of households with the selected telephone numbers. Trained and qualified interviewers conducted the survey with the aid of computer-assisted interviewing facilities. The facilities can ensure the correct flow of the interview and the quality of data input. The pretest served to improve survey questions so as to guarantee their clarity, comprehensibility, legitimacy, and feasibility when used in the full-scale survey.

2.The response rate of the full-scale survey was 36.2%, estimated in terms of the ratio of the number of successful interviews to the sum of that number and the number (2,016) of households that refused to participate in the survey.

3.To maximize the representativeness of the data, a weighting procedure attached a weight to each case according to the age and sex of the respondent so as to make the resultant distribution of age and sex equivalent to the population projected for 1999 (based on the 1996 bi-census). That is, a case whose age and sex were underrepresented in the sample relative to the population would be more important and thus have a weight higher than one. Conversely, a case whose age and sex were overrepresented in the sample would have a weight lower than one. As a result, distribution figures in terms of unweighted and weighted data are available. In addition, figures are available for the case that excludes missing values due to “not understanding” and “not willing to answer.” These figures derived from the assumption that those not understanding or not willing to answer would have the same distribution of valid responses as those giving valid responses.


Profile of the Sample


4.Respondents’ age ranged from 15 to 87 years, with an average of 37.1 (see Table 1). The average age was slightly lower the mean (40.9) of the population, as a result of the weighting procedure that equated the distribution of the sample to that of the population in age and sex. The sample tended to overrepresent respondents aged between 15 and 19 years. After application of the weighting procedure, the weighted proportion of the youngest category reduced. The sample consisted slightly of more female respondents than male respondents (52.9% vs. 45.8%; 1.3% unidentified, see Table 2). After weighting, the proportion of male people became closer to that of female people. An overwhelming majority (97.8%) of the interviews employed Chinese as the medium (see Table 3). Only 25 interviews used English as the medium. Most respondents attained the senior secondary level (Secondary 4 to Secondary 7) of education (see Table 4). Few people had not received any formal education. About 70% of the population aged 15 or above did not have religious faith (see Table 5).

Opinions on the Age of Criminal Responsibility

5.The majority of the population with age of 15 years or above preferred the age of criminal responsibility should be at least 8 years or above (see Table 6). According to the weighted figures with missing excluded, 89.4% of the population preferred such an option. This figures also assumed that 89.4% of those failing to give responses to the question would also preferred a minimum age of 8 years or above for criminal responsibility. At any rate, the exact proportion might be between 86.7% and 89.4%, depending on the true preference of those who failed to give responses to the survey question. On the other hand, only 0.9% of the population preferred to have criminal responsibility beginning at an age under 7.

7.According to weighted data, 18.1% of the population preferred the minimum age of criminal responsibility to be 18 years (see Table 8). This age was the most popular among the population. The next popular minimum age of criminal responsibility was 16 years, with 15.5% of the population favoring that age. Few people preferred the minimum age to be 19 years or above. The average minimum age preferred by those preferring a minimum age of 8 years or above for criminal responsibility was 14.5 years. More than half (52.1%) of the population clearly suggested their preferred minimum age of criminal responsibility to be 14 or above. In other words, among those indicating a minimum age that was 8 years or above, 67.5% indicated an age of 14 years or above.

8.Combining data from 900 (7 indicating an age below 7, 17 preferring the age of 7, and 876 indicating an age of 8 or above) respondents who indicated their preferred minimum age of criminal responsibility, the weighted mean of the preferred age was 14.4 years, which represented the average of preferred age in the population of people aged 15 years or above in Hong Kong. The age of 14.4 would be the best estimate of the preferred minimum age of criminal responsibility for anyone aged 15 or above. Associated with the estimate was a standard deviation of 3.36 years, which meant that an individual in general might have an average deviation of 3.36 years above or below the average preferred age of 14.4 years (i.e., between 11.04 and 17.22). On the other hand, 15.6% of the population would have a preferred minimum age around 14 and 15 years.

9.Weighted data indicated that 6.4% of the population indicated the rebuttable presumption of doli incapax was right (an answer of “right” to the question, “Do you think the current rebuttable presumption of doli incapax for persons between 7 and 14 years of age is right or not?”) (see Table 9). Only 0.7% of the population indicated the rule was not right and required change. Moreover, 1.9% of the population reported that the rule was not right but it did not require change.

Note: The “not applicable” were those not necessary to answer the question because they did not prefer a range of 7 and 14 years for the rebuttable rule.

10.To persons aged between 7 and 14, only 2 respondents suggested to lower the upper age for applying the rebuttable presumption of doli incapax (answer the question, “How do you think the current rebuttable presumption of doli incapax should be changed?”) (see Table 10). Only one respondent suggested to raise the upper age and only one respondent preferred to abolish the rule. Hence, very few of the population indicated the way of changing the rule.

11.None of the respondents who suggested either to lower or raise the upper age reported an age instead of the upper age of 14.

(see Table 11). Only 0.3% of the population thought that applying the rule was not right.

(see Table 12). Only 4.1% of the population thought that applying the rule was not right but did not require change and 3.7% of the population thought that applying the rule was not right and required change.

15.To lower the upper age for applying the rebuttable presumption of doli incapax to persons aged between a suggested raised minimum age and the upper age, 1.4% of the population suggested an upper age from 3 to 12 years (see Table 14). Among these lowered upper ages, the age of 12 was the most popular, with 0.8% of the population showing such a preference.

(see Table 16). This was only slightly more than the 6.0% of population who disagreed to apply the rule.

18.Overall, 28.4% of the population thought that applying the rebuttable presumption of doli incapax was right to persons aged either between 7 and 14, between 7 and a more preferable upper age, between a more preferable lower age and 14, or between a more preferable lower age and a more preferable upper age (see Table 17). This proportion was considerably greater than that (6.9%) agreeing to apply the reverse rebuttable presumption of doli capax. Support for the rebuttable presumption applied to persons between a raised minimum age and 14 years accounted for a large portion of the overall support (75.4% = 21.4% (see Table 12) /28.4% (see Table 17)).

19.To sum up,
19.1Support was most remarkable for considering the age of 8 years or above as the minimum age of criminal responsibility (89.4% of the population);
19.2Preference for a minimum age of 14 years or above for criminal responsibility was present in 52.1% of the population;
19.3The average age regarded as the minimum age of criminal responsibility was 14.4 years;
19.4More than a quarter (28.4%) of the population supported the rebuttable presumption of doli incapax in general;
19.5Slightly more than one-fifth (21.4%) of the population supported applying the rebuttable presumption of doli incapax to persons between a raised minimum age and 14 years;
19.6Support for the rebuttable presumption of doli capax was low (6.9%);
19.7Support for the current application of the rebuttable presumption of doli incapax to persons between 7 and 14 years of age was similarly low (6.4%).

20.The distribution of responses to critical concerns about the minimum age of criminal responsibility, the rebuttable presumption of doli incapax, and change for the rule is shown in the following chart.
age01.jpg


21.Accordingly, the overwhelming majority (89.4%) of the population preferred a minimum age of 8 or above. Among this majority, 59.6% indicated an age of 14 or above. Again out of this majority, 21.4% of the population thought that the rebuttable presumption of doli incapax was right. This figure represented 66.3% of those who indicated a minimum age between 7 and 14. Furthermore, 6.4% of the population thought that the rebuttable presumption of doli incapax was right to apply to persons aged between 7 and 14. Another 0.9% of the population also thought that the rule was right to apply to persons between a preferable age below 7 and 14. In total, 28.4% of the population thought that the rebuttable presumption was right. On the other hand, only 4.4% of the population thought that the presumption was not right and required change.

Knowledge about the Age of Criminal Responsibility

22.About 30% of the population reported that they knew that criminal responsibility did not apply to persons aged under 7 years (see Table 18). In addition, 22.6% of the population reported that they knew that the rebuttable presumption of doli incapax applied to persons aged between 7 and 14 years (see Table 19).

Opinion on Criminal Responsibility among Various Characteristics


23.At the outset, the study was conscious of variation across or contamination by background characteristics including religious faith, education, sex, age, and use of English, and knowledge about the law of criminal responsibility. To determine and eliminate the bias, breakdown of the distribution among various characteristics was necessary. The breakdown involved a test of association between each characteristic and opinion. The appropriate measure of association would be Cramer’s V which ranges from 0 to 1, with 1 indicating maximum association and 0 indicating no association. Cramer’s V was a typical measure of association between categorical data.

24.Concerning the first question about the age of criminal responsibility, breakdown analysis indicated that age and education had significant associations with the preferred age. On the contrary, sex, religion, use of English, and knowledge about the law of criminal responsibility made no difference in the distribution of responses regarding the age of criminal responsibility (see Table 20).

25.Regarding the association with age, people aged between 20 and 29 were most (94.0%) likely to prefer the age of criminal responsibility to be 8 or above. On the other hand, people aged 70 or above were least (79.7%) likely to prefer the age of 8 or above. Results also show that people aged between 50 and 59 were relatively more (4.1%) likely to prefer the minimum age of criminal responsibility to be 7 years, among the population.

26.Regarding the association with education, people with senior secondary education were most (92.5%) likely to prefer the age of criminal responsibility to be 8 or above. On the other hand, people with no formal education were least (71.7%) likely to prefer the age of 8 or above. They instead were most (25.0%) likely to be uncertain about the age of criminal responsibility, among the population.
