For whatever it's worth, NW Arkansas has a lot more cultural diversity because of the large employers drawing people from all over to work here and because of the University of Arkansas in Fayetteville. In small rural towns in Arkansas like Harrison, that may not be the case. The crime rate in NW Arkansas is also low.
NW Arkansas is on all kinds of quality of life, Best Places to Live lists. Our family moved here about 16 years ago when my son was 7. We have not regretted it.
