Mr. Speaker, the United States has a period of 20 years shorter. The United Kingdom has a 6 to 8 year period that is longer. So the 92 years is a reasonable compromise. It was also looked at as a time period in which those citizens that had been interviewed or had filled out the census form would have passed on. Obviously, that has changed since the 1911 period which is the census we are looking at. But that is what it is. It is somewhat of a balance between the standard in the United States and the United Kingdom.
