Resources that you may consult to help with this question are the Philadelphia Police Department, The Philadelphia Inquirer online special crime report. Do some research on the 19121 zip code in general.
The area you refer to has a lot of Temple University students co-mingled with generations of longtime residents. Like all of Philadelphia, it's block-to-block. I always recommend visiting a home at night during the week and on the weekend before committing to a purchase.
