Most of this data involves STATA 7.0 data sets. The reason for using this is that the county level data involves a much larger set of control variables than can readily be handled by other statistical packages.  To help with the variable names:

for the demographics

pp = percent of the population

w= white

b= black

n= neither black or white

m= male

f= female

1019= 10 to 19 years of age, etc

so ppbm1019 = percent of the population that is black male 10 to 19 years of age

 

rpcpi = real per capita personal income

rpcim = real per capita income maintenance (welfare type payments)

rpcui = real per capita unemployment insurance

rpcrpo = real per capita retirement gov payments (SS, medicare)

 

CCWage = age eligible to have a concealed handgun permit

assaultweaponsban2 = assault weapon ban, either state or federal

 

the crime data is the natural log of the crime rate (though .01 is added to the crime rate when it is equal to zero)

ao stands for the arrest rate data by type of crime

The data and its sources are described in the data appendix for my book More Guns, Less Crime (University of Chicago Press, 3rd edition, 2010).
