II. Data Sources

1. Type of statistical materials

Statistics, figures, tables and other calculated data are provided by the following bureaus/department of the Ministry of Justice; Judicial System Department of Minister’s Secretariat, Criminal Affairs Bureau, Correction Bureau, Rehabilitation Bureau and Immigration Bureau. Data are also obtained from various researches and surveys conducted by relevant agencies, as well as from the following official statistics.


2. Coverage of statistical materials

Statistical materials cover the period up to 2010 available at the end of July 2011.

For those statistical data for 2010 that were not available in form of official publication at the time of drafting, raw data offered by relevant agencies were used. Those data are provisional in nature and may differ from the corresponding data in the subsequent publication. In such cases, the relevant figures will be corrected in the White Paper on Crime for the coming years. In addition, the same correction will be made with any change within the official statistical publications.

III. Presentation of Figures and Tables

1. Numbering of figures and tables

The numbering of figures and tables are indicated in the order of the part, chapter, section (for example, Fig. 2-4-3-1 indicates Figure 1 of Section 3, Chapter 4, Part 2).

2. Presentation of values, etc.

IV. Others

1. In the White Paper on Crime, “treatment” refers to treatment that persons cleared by police or other investigative authorities receive at each stage of prosecution, trial, correction, and rehabilitation.

2. Calculation method

The proportion and percentage, etc. are rounded off. Therefore, the figures for proportion may not add up to 100.0.

In addition, the sum or difference of each proportion is calculated by first adding or subtracting values and then rounding off the resulting value. Thus, the value may not match the value calculated by first rounding off each value and then adding or subtracting rounded off values.

For example, when calculating the difference between 12.76 and 7.53, the result 5.2 obtained by first subtracting 7.53 from 12.76 and then rounding off the value 5.23 does not match the result 5.3 obtained by subtracting the rounded off value of 7.5 from the rounded off value of 12.8.
