I am writing my Final for Criminal Psychology PSY310 and I am trying to figure out how to do a demographic summary.  I am doing mine on the case of Frank Timmons who was a serial Killer. If you could help me out on how to develop a demographic summary that would be great thank you.

Develop a demographic summary of the individual based on analysis of data from the case.

Reference I have:
