This page provides some basic statistics concerning the data recorded about the soldiers in the database.
Note that not all values for all soldiers have been recorded, so the statistical sample size (referred to as "Count") may vary depending on the criteria.
Total number of soldiers in the database: 180,401
Total number of CEF personnel (1914-1919): 619,636
Total number of CEF died or missing: (1914 - 1926): 58,990

Note: Only a portion of all soldiers are entered and the data is not complete. The data will be more relevent for groups

Introduction to Statistics
This provides a short introduction to the statistical functions used on this page
The minimum or lowest value (age or height) from the sample set
The maximum or largest value (age or height) from the sample set
The average value calculated as the sum of the values divided by the number of values.
This illustrates the difference between the average value and the extremes. The larger the variance, the wider the spread between the average value and the minimum or maximum value.
Often referred to as "Sigma", this represents how close the numbers are to each other. A small deviation indicates that most of the numbers are close together.
This is the number of values used to calculate the statistics. If no data is available for the specific calculation, for example soldiers that survived the war should not be included in the "Age at Death" calculations. The number is representative of the quality of the calculations; the higher the number the higher the probability that the calculations are meaningful.
This shows the percentage of the total number that is represented by the "count". Value. For example, the percentage for age of death shows the percentage that the count represents for the total number of CEF soldiers that have an age at death (date of death and date of birth, or age at death) specified.
