6 Politics 0 Policy Vol. 32 No.4 a county, and whether the county is a Delta county.] County size and the number <strong>of</strong>highway miles in a county are expected to have a positive impact on arrests and crashes because more automobile traffic will likely take place. Finally, the geographic significance <strong>of</strong>the Delta is that due to its proximity to the Mississippi River, the land there is flat, while land in the rest <strong>of</strong>the state is <strong>of</strong>ten hilly or mountainous. Thus, we expect fewer crashes in Delta counties. In order to assess the inclusion <strong>of</strong> these independent policy and control variables, we use a multivariate model <strong>of</strong>statistical analysis. 2 Methodology In this study we consider 74 <strong>of</strong>75 Arkansas counties. We drop from our analysis Pulasld County, home to Little Rock and 350,418 residents because it is the only urban county in a predominantly rural state and it has had a skewing effect on data analysis. Data analyzed in this study were collected by the Institute for Economic Advancement at the University <strong>of</strong>Arkansas at Little Rock (UALR) and titled, "Risk Factors forAdolescent Drug andAlcohol Abuse in Arkansas." These data were collected for use by the Arkansas Department <strong>of</strong> Health, Bureau <strong>of</strong>Alcohol and Drug Abuse Prevention and consider juveniles as those between the ages <strong>of</strong> 10 and 17 and adults as those who are older than 18 years. Drug-related arrests for juveniles and adults are based on violations such as possession, sale, use, growing, and manufacturing <strong>of</strong>illegal drugs. Alcohol-related arrests are basedon such violations as driving under the influence (DUI), liquor law violations, and public drunkenness. Population data were compiled by Demographic Research, Institute for Economic Advancement at UALR and the number <strong>of</strong>police were compiled from data collected by the Arkansas Crime Information Center (1997). Alcohol Policy and Arrest Rates The first stage <strong>of</strong> analysis is a repl ication <strong>of</strong> Grossman's (1997) study. Here we analyze arrest rates in the 74 rural counties <strong>of</strong>Arkansas. Data are transfonned, in line with Grossman's study, to reflect arrests per 1,000 people, and in the case <strong>of</strong>juvenile arrests, per 1,000 <strong>of</strong>those aged 10-17. Departing from Grossman, we consider four variables:juvenile drug arrests, juvenile alcohol arrests, adult drug arrests, and adult alcohol arrests. An analysis <strong>of</strong> descriptive statistics, illustrated in Figure I, reveals that juvenile alcohol and drug arrest rates are significantly lower than adult alcohol arrests and slightly lower than adult drug arrest rates, as can be expected
