Hello! This is Hanbit from Chicago, IL. I'm currently learning data analytics at General Assembly. This is one of my analysis projects I worked by myself in the course with SQL and Excel based on Iowa liquor sales database. -Scenario: assumed Iowa officials asked to recommend 5 counties for an alcoholism targeting program based on liquor sales -Approach: defining clear business questions from the scenario and data, using SQL for big scale data extraction and aggregation, and using Excel for conditional formatting and visualization with pivot tables and charts -Findings: not only focused on sales but also came up with the number of active status stores and alcohol consumption per county -Highlight: selected five counties with the analysis results appropriately by scoring the county rank of each category which were mentioned in the analysis results Thank you.

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

15. 5 counties of Iowa selection for
alcoholism program based on Iowa
liquor sales database
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

16. 5 counties of Iowa selection for
alcoholism program based on Iowa
liquor sales database
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 program
3. Excluding counties that already enrolled in the alcoholism program by Iowa
4. Excluding Dickinson which has small population but the highest alcohol consumption rank because of many tourists
