Not really, America is a HUGE country. It just depends on where you live and the types of danger will also be different. Where I live people go jogging in pitch darkness past 12 am all the time, especially around this time during the summer.
If you're walking in lets say Bakersfield, you're more likely to get driven over by a drunk person than getting mugged. If you're walking in San Luis Obispo at midnight you'll probably die from being stabbed in the foot by seashells. If you're walking in Santa Cruz, you'll probably die by getting eaten by a mountain lion. Etc.. Etc..
