Decline in the incarceration rate may be due to changes in incarceration guidlines.

Fayetteville, NC specifically according to the Carolina Public Press:

"Crime rates in Fayetteville are down a sixth consecutive year. Unfortunately, violent crimes — homicides and aggravated assaults — are up.

"That puts the county’s overall crime rate 150% higher than the statewide average despite the recent declines. Worse, violent crime in Cumberland County is 71% higher than the statewide per 100,000 rate." See link below

Overall crime rate rate is down more than 10%, yet homicides and aggravated assaults are up.  

Story behind the curve according to this source as well as data presented at the 2023 EDNCPHA, COVID-19 pandemic appears to be the reason for the phenomenon.
