Baltimore and memphis are almost identical in many ways:
Population: 620,000 (Baltimore) vs. 646,000 (Memphis)
African-American population percentage: 63.2% (Baltimore) vs. 62.6% (Memphis)
Non-Hispanic White population percentage: 31% (Baltimore) vs. 29% (Memphis)
Median household income: $30,000 (Baltimore) vs. $32,000 (Memphis)
Unemployment: 11.4% (Baltimore) vs. 10.7% (Memphis)
Households below poverty line: 19% (Baltimore) vs. 21% (Memphis)
Average August temperature: 88 (Baltimore) vs. 91 (Memphis)
But they are very different regarding two other statistics:
2010 Homicides: 223 (Baltimore) vs. 93 (Memphis)
Homicides per 100,000: 35.9 (Baltimore) vs. 14.4 (Memphis)
That's almost two and half times as many homicides for Baltimore.
Here's another important difference: it is almost impossible for a law-abiding citizen in Baltimore to legally own a firearm. Under Tennessee law a person cannot be charged with possession of an unlicensed firearm if it is used in self-defense.
