EXTERNAL INFO

1) There is already a program targeting alcoholism in Iowa

Source : Iowa Department of Public Health

• Polk, Scott, Blackhawk, and Woodbury are #1, #3, #5, and #7 in total sales rank• These are #1, #3, #4, and #5 in population rank • Also, #2, #5, #6, and #15 in sales per resident rank• These are all included in TOP 15 alcohol consumption per resident except Woodbury county




EXTERNAL INFO

2) Revocations info including drunk driving

Source :The des moines register http://www.desmoinesregister.com/story/news/crime-and-courts/2016/04/30/driving-while-intoxicated-wrong-way/83651312/

Operating While Impaired means operating a motor with a blood alcohol content (BAC) of 0.08% or above, or while under the influence of drugs

• Polk, Woodbury, and Scott county, which are top ranked in terms of revocations, already have an alcoholism program called SBIRT IOWA since 2012




LIMITATIONS / ASSUMTIONS

Dickinson is a small population county but #1 drink per county, #1 sales per resident, and #3 residents per liquor store so I searched…

Source : Wikipedia

Assumed many visitors drink in Dickinson so the sales and the consumption goes high with no population change

No customer data / No demographic information Only retail store sales data included with no bars, restaurants, and others

• limitations in this analysis with Iowa liquor sales date set?

Tourists destination




CONCLUSION

How to select five counties with the analysis results appropriately?

By scoring the county rank of each category which were mentioned in the analysis results




CONCLUSION

Therefore, my recommendation is…

Johnson, Linn, Pottawattamie, Cerro Gordo, and Hardin

1. Listing up all the counties which were mentioned in the analysis results 2. Scoring the county rank of each category, calculating total score, and the smallest score counties should be considered for this

alcoholism program3. Excluding counties that already enrolled in the alcoholism program by Iowa4. Excluding Dickinson which has small population but the highest alcohol consumption rank because of many tourists
