On December 15, 2013 I published a “meme” on facebook comparing mail volumes in 1988/89 with the volumes in 2012. The figure used in the graphic for 2012 was incorrect.
The image above has been corrected to show 9.6 billion pieces of mail moved in 2012 instead of the incorrect number of 9.8 I published on December 15.
Both the 1989 number and the 2012 number were rounded to the nearest 100 million.
The 1989 number comes from a Fraser Institute report titled The Mail Monopoly published in 1990 which quotes the employer’s 1988/89 annual report. The report can be downloaded here. On page 115 of the report you can find the following table.
The 2012 number comes from the employer’s annual report (financial) which can be viewed here. On page 59 of the report you can find the following table.
I should have taken the 9,623 million figure from this table and rounded it down to 9.6 billion pieces. Somehow I ended up publishing the meme with the 9.8 billion figure in error.
I am not sure how this error occurred. I had a lot of documents opened on my screen at the time. Whether I was looking at another figure while editing the meme or it was a simple type-o, I got it wrong.
I apologize for any misunderstanding that my error has caused.
