I tried to list all of the ways and I really ran out of space.
The most important application that lawyers and law students need to know about is how to adequately prepare, identify, and deal with expert testimony in a whole range of cases. Socio-economic data is one of the key areas, so in my charter litigation involving groups such as Métis women, same-sex couples, and so on, I have had to continually confront the data limitations that the Canadian statistics scene offers.
Also in my own personal research, which is fairly wide ranging and has been funded by everyone from SSHRC to Status of Women Canada and private foundations, I have carried out in-depth research that is usually demographically diversity oriented and requires me to make very heavy use of all of Statistics Canada's products. As well, I've done sort of international, transnational comparative statistical work, so I'm familiar with statistical practices from a large number of developed and underdeveloped countries also.
