Flaws in the 2010 Winnipeg Police Annual Report – Part III

This post will examine the “Events for Service” statistics listed in the 2010 Winnipeg Police Annual Report.

As the table below indicates, in 2009 there were 162,394 events.  In 2010 there were 162,678.  The difference is so marginal that in percentage terms it is correctly listed as zero.

The variances in the number of events for service in the 5 Districts are listed as between -3 and -10 percent.  This raises the question:  If the actual city-wide calls for service were essentially static then how is it possible that each District would show a reduction?

The culprit again is the new unexplained category ‘Not District Specific” introduced in 2010.  This category which consists of 7748 events when added to the 2010 District numbers produces a variance of zero as opposed to the listed 3 to 10 per cent decrease.  Again, another error.

Based on the response I have received to these recent postings, there is significant interest in what will hopefully be a response in the near future from the Winnipeg Police Service as to why the “Not District Specific” category was introduced, or what it represents.
