Crime in Atlanta, Georgia is above the national median and has been a major problem for the city since the middle 20th century. Atlanta’s public safety improvement between 2001 and 2009 occurred at more than twice the rate of the rest of the country. After ranking in the top five highest violent crime cities for most of the previous three decades, in 2009 Atlanta ranked 31st, and in 2015, 24/7 Wall Street ranked it 19th. While various news sources report rankings by crime rate, FBI strongly cautions against comparing different cities' crime rates, as such a misuse of bare statistics ignores various important factors, such as population density, degree of urbanization, composition of population, economic conditions, etc.
