I have several young men and women who I cannot trace on the British 1901 census, despite numerous and extensive efforts. While there are a number of reasons why I might not be able to find them, one that I have not yet ruled out is that they were serving in the military abroad.
At the time of the 1901 census, the Second Boer War (1899-1902) was near its height.
How many (or what percentage of) British men and women were serving in the Boer War at the time of the 1901 census, and are therefore not enumerated on that census? Should I consider it likely that a missing woman on the 1901 census may have been a nurse or otherwise serving in the Boer War? Any additional demographic data (age, occupation, etc.) about those serving in the Boer War would be a bonus.
