For your clarification, and Ms. Blaney's as well, the Canadian Armed Forces superannuation pension plan, which includes that optional survivor benefit, doesn't fall within the jurisdiction of Veterans Affairs Canada. It is a superannuation plan led by our colleagues in the Canadian Armed Forces and Treasury Board Secretariat.
We will be coming back to this committee in a few weeks, along with those partners, who may be better positioned to describe the details and the evolution of that. I would not have the historical information about the evolution of that element. I think this is an important distinction or clarification to make.
What I can say, though, is that the Government of Canada, through Veterans Affairs Canada, is very interested in making sure that families and survivors of veterans have the supports they need. Ms. Blaney mentioned earlier that government did infuse money, the $150 million, into a veterans survivor fund. What we've done since that time is undertaken research along with Statistics Canada and the Canadian Institute for Military and Veteran Health Research. We have some preliminary results and, when we come back in two weeks, hopefully we can dive into those a little more.
What I can tell you about this group of individuals who may fall into the category of marrying a member after the age of 60 is that there are just under 5,000 living survivors who would have entered into a relationship post age 60. Virtually all were female. Most, or approximately 90%, were of the age of 70 years or older. Overall, their incomes were just slightly higher than similarly aged Canadian females' income. Of those close to 5,000 individuals, there were approximately 850 who had incomes below the low income measure, and about 1,200 who were in receipt of the guaranteed income supplement.
We're taking this information into account, as well as the increase in the old age security that will come into effect in July 2022, which will infuse additional funds for those aged over 75. We want to take into account the risk level of this population so that we can put into place a program and supports that will meet those needs. I hope to come back and talk with you more about that in the coming weeks with our partners.
