Answer:
Crime rates peaked in the 1990s and have been in sharp decline ever since
Step-by-step explanation:
Violent crime in San Francisco increased in 2015, but that was a trend that has stopped for a while since the 1990s. Between 1960 to 1980, California as a whole experienced a high rate of crime, increasing from 236 to 888 violent crimes per one hundred thousand residents. However, California and San Francisco which was a major contributor to the high crime rates saw its crime rate rise to a peak in 1992. However since then, there has been a substantial decline in the rate of crime in San Francisco and California as a whole.
