Total and averages are based on the number of years for which that particular statistic has been gathered. For example, BGEA statistics have been gathered for 30 years, so the total is divided by 30; e-mail statistics have been gathered for 17 years, so that statistics is divided by 17. No statistic has been gathered for less than 17 years.
