b)      Using the rates your calculated in part a, calculate the percentage change between 1997 and 2001 for each state and each province. Which states and provinces had the largest increase and decrease? Which society seems to have the largest change in homicide rates?

Explanation / Answer

a)

relatively speaking,

States: Alabama has highest homicides rates in both 1997 and 2001 years

Provinces: British Colum has highest homicide rate in 1997 and Manitoba has highest rate in 2001

whereas no state has increased homicide rate in 2001 compared to 1997

in Provinces, Quebe has highest increase in 2001 compared to 1997 and Nova Scotia has highest decrease in homicide rates.
