The report said
"main reasons given for the movement, people told Newsweek, were politics, the cost of living, taxation—and crime. " You use statistics like a drunk uses a lamp pole. You use them for support, not illumination. Regardless of the headline, that article pretty much debunks that idea.
Per national data, Houston and Arlington, two of Texas's top cities, crime rates are not significantly different from that of San Francisco and their murder rates are many times greater than that of SF. So, I'd answer your question:
"As far as crime and Democratic ran cities explain why people are leaving them for Red States.", I'd say they aren't. Maybe they listen to yokels who cite crappy articles and repeat their perception when asked, but in reality, they aren't really moving because of crime. They give other reasons, politics, cost of living and taxation as well.
People move for plenty of good reasons. I chose to leave CA decades ago to move to Idaho for a better job offer. I moved to Oregon for the same reason. They all have fairly low crime rates. In fact the US has low crime rates compared to what it was during the mythical MAGA era of Ronald Reagan.
So, you use statistics, I can use statistics too. What you cited was perception, I'll see you that and raise you with reality.
