Knowing which places are risky can be an important aspect of where we
choose to spend our time and, if we must place ourselves at greater
risk, how we spend our time in those places. But how do we measure risk?
In this lecture, we will go over issues of scale, data sources, and
metrics. The crime and place literature has repeatedly shown that risk
is best measured at micro-places, knowing where people actually are
impacts how we assess risk, and there are many ways to measure risk at
places. Using data from Vancouver, Canada we will investigate these
issues showing their importance for crime analysis and spatial-temporal
criminology, more generally.
