Title: Communities and Crime

Abstract: Communities within the United States. The data combines socio-economic data 
from the 1990 US Census, law enforcement data from the 1990 US LEMAS survey, and crime 
data from the 1995 FBI UCR.

Data Set Information:

Many variables are included so that algorithms that select or learn weights for 
attributes could be tested. However, clearly unrelated attributes were not included; 
attributes were picked if there was any plausible connection to crime (N=122), plus 
the attribute to be predicted (Per Capita Violent Crimes). The variables included in 
the dataset involve the community, such as the percent of the population considered 
urban, and the median family income, and involving law enforcement, such as per capita 
number of police officers, and percent of officers assigned to drug units.

The per capita violent crimes variable was calculated using population and the sum of 
crime variables considered violent crimes in the United States: murder, rape, robbery, 
and assault. There was apparently some controversy in some states concerning the 
counting of rapes. These resulted in missing values for rape, which resulted in 
incorrect values for per capita violent crime. These cities are not included in the 
dataset. Many of these omitted communities were from the midwestern USA.

Data is described below based on original values. All numeric data was normalized into 
the decimal range 0.00-1.00 using an Unsupervised, equal-interval binning method. 
Attributes retain their distribution and skew (hence for example the population 
attribute has a mean value of 0.06 because most communities are small). E.g. An 
attribute described as 'mean people per household' is actually the normalized (0-1) 
version of that value.

The normalization preserves rough ratios of values WITHIN an attribute (e.g. double 
the value for double the population within the available precision - except for 
extreme values (all values more than 3 SD above the mean are normalized to 1.00; all 
values more than 3 SD below the mean are nromalized to 0.00)).

However, the normalization does not preserve relationships between values BETWEEN 
attributes (e.g. it would not be meaningful to compare the value for whitePerCap with 
the value for blackPerCap for a community)

A limitation was that the LEMAS survey was of the police departments with at least 100 
officers, plus a random sample of smaller departments. For our purposes, communities 
not found in both census and crime datasets were omitted. Many communities are missing 
LEMAS data.
