The rate of murder is going down in US

I visited the CNN website which is talking about the rate of crime in the United States. According to this website, the rate of murder is going down and in 1997 it became the lowest level for murder in 30 years, but the rate of the young Americans murders is going up. The website tell us about what the White House said; they said "the rate of murder especially the homicide should continue to decline into next year" which is of course good news for American people. According to the website the firearm killings by people who are age 25 and older is going down; it plummeted by roughly half between 1980 and 1997 but it is going up by the young people who are ages between 18 and 24 from about 5,000 killings by firearms in 1980 to more than 7,500 in 1997, and there are other findings but I think the most important one is that the murder rate is high in the South and on the West Coast and low in New England and the Rocky Mountain states.

In my opinion, this website tells us about the rate of murder in the United States and which people do more murders depends on the age and other things like gender and color, I didn't mention gender and color in my summary, but anyone can visit the website and read about that. This of course is good news for people who live in the United States even if they are citizens or residents. I don't know why the rate of murder going down, but I think it is more then one reason for example better police, less guns and more employment opportunities.
