What do we want to measure?

At the expense of sounding too repetitive, I agree with everyone above that focusing on Vancouver is the most ideal solution, thereby narrowing the breadth of our sample audience. This is significant, in that while it is important to be broad when generating a research question, it is also important to conceive a concise question that has a singular focus (the entire Lower Mainland may be too broad and diverse when it comes to issues of homelessness and poverty). I also agree with Hana's point that the results with a more centered focus will be more comprehensive and meaningful.
