So, we can see the most correlated values on this page. PctIlleg (percentage of kids born to never married) and racepctblack ( percentage of population that is african american) are very correlated with our value to estimate. I'm french and in my point of view the race has no interest. For me, it's not the race but the fact that people can live in poor area with more public assistance as the next correlated value named pctWPubAsst.
At the inverse , we cans see the racePctWhite (percentage of population that is caucasian), PctFam2Par (ercentage of families (with kids) that are headed by two parents) and PctKids2Par (percentage of kids in family housing with two parents) completing the fact that a stable family (strangely white by the race) is a decisive information to not have violent crimes on the area.

pctUrban is poorly correlated with our value. The fact of be in an urban area or not is not decisive to estimate our value.
PctSameState85 (percent of people living in the same state as in 1985 (5 years before)) and PctVacMore6Mos  (percent of vacant housing that has been vacant more than 6 months) have not an important effect in our future estimation.

I think that you can continue to verify by yourself this important list of comparison by yourself.

I hope to give the most important facts or summary of these values.

The most important in my first feeling is to say a stable and an unstable family and social area should be an important cause of the number of violent crimes. This is really important, because it proves that a politic based on security purchase or based on non management of the unemployment or social priorities could not have a direct effect on the violent crimes existence. At the inverse , in stabilizing the social family an context with a complex social politic should permit to decrease considerably the violent crimes.
