《破案率怎么计算》

在当今的社会中，破案率是评估公安部门工作成效的一个重要指标。那么，破案率究竟是如何计算的呢？

首先，我们需要明确破案率的基本概念。破案率指的是破案数占立案数的百分比。用数学公式来表达，就是破案数除以立案数的结果。

公安部门在年终会对所有案件作出总结，用已经侦破的案件数量除以年度总的案件数量，这样得出的就是年度破案率。需要注意的是，每年都会有一些案件无法在当年侦破，这些未侦破的案件会继续侦办，但不会记入到下一年的破案率计算中，而是有专门的以往案件结案率来进行统计。

对于破案率的计算，还有更详细的解释。破案率是利用刑事案件发案数、破案数的相对指标进行的专题分析，属公安机关统计分析的一种。在特定的地区范围（如某省、市，某县、区或全国）和一定的期间内，破案数占发案总数的比重就是破案率。其计算式是：破案总数除以发案总数再乘以 100%，即破案率。

一般情况下，统计数字有一个规定的年度截止时间。比如，每年的 12 月 20 日，以前的算当年度，以后的算入下一个年度，这样一刀切的方式使得统计更加清晰明确。

总之，破案率的计算并非简单的数字运算，它背后反映的是公安部门的工作效率和社会治安状况。准确计算和理解破案率，对于评估公安工作、制定治安策略以及增强公众对社会治安的信心都具有重要意义。

"How to Calculate the Detection Rate"

In today's society, the detection rate is an important indicator to evaluate the effectiveness of the public security department. So, how exactly is the detection rate calculated?

First of all, we need to clarify the basic concept of the detection rate. The detection rate refers to the percentage of solved cases among the total number of filed cases. Mathematically expressed, it is the result of dividing the number of solved cases by the number of filed cases.

The public security department summarizes all cases at the end of the year. The number of cases that have been solved is divided by the total number of cases in the year, and the resulting figure is the annual detection rate . It should be noted that every year, there are some cases that cannot be solved in the current year. These unsolved cases will continue to be investigated, but they will not be included in the calculation of the detection rate for the next year. Instead, there is a separate statistics for the结案 rate of previous cases .

For the calculation of the detection rate, there are more detailed explanations. The detection rate is a special analysis using the relative indicators of the number of criminal cases and the number of solved cases, and it is a kind of statistical analysis of the public security organs . Within a specific regional scope (such as a certain province, city, county, district, or the whole country) and within a certain period, the proportion of the number of solved cases to the total number of filed cases is the detection rate. The calculation formula is: the total number of solved cases divided by the total number of filed cases and then multiplied by 100%, which is the detection rate .

In general, there is a stipulated annual cut-off time for statistical figures. For example, before December 20 of each year, it is counted as the current year, and after that, it is counted as the next year. This clear-cut method makes the statistics more clear and definite .

In conclusion, the calculation of the detection rate is not a simple arithmetic operation. What lies behind it reflects the working efficiency of the public security department and the social security situation. Accurate calculation and understanding of the detection rate are of great significance for evaluating the public security work, formulating security strategies, and enhancing the public's confidence in social security.
