standardize by population density

I have a variable called "number of events" for each state. It is a raw number of event that happened during a specific time frame. I was thinking I could use the population density or weighted population density to standardize the number of events across states. Is this correct? I would divide (or multiply?) the number of events by the state's population density (or weighted population density) to get a standardized number of events.

I chose population density so that I could compare the number of events between states with diverse population structures.
