Iowa Liquor Sales dataset via Socrata/data.iowa.gov

(preliminary exploration)

The state of Iowa has released an 800MB+ dataset of more than 3 million rows showing weekly liquor sales, broken down by liquor category, vendor, and product name, e.g. STRAIGHT BOURBON WHISKIES, Jim Beam Brands, Maker's Mark

This dataset contains the spirits purchase information of Iowa Class “E” liquor licensees by product and date of purchase from January 1, 2014 to current. The dataset can be used to analyze total spirits sales in Iowa of individual products at the store level.

You can view the dataset via Socrata

Here are some steps to get the data wrangled. Do your own visualizations/analysis. But it looks like as good of dataset as any to see such things as:

  • Purchase trends during holidays and college football season
  • Most popular brands and types of alcohol
  • Price variance between same-city stores and different-city stores
  • Popularity of Hawkeye Vodka in Iowa City versus Ames

The metadata

The URL for the metadata via Socrata's API, is:

https://data.iowa.gov/metadata/v1/dataset/m3tr-qhgy.json

Or you can see a cached version here. The metadata contains column names and datatypes.

Download it

# bash
curl https://data.iowa.gov/api/views/m3tr-qhgy/rows.csv?accessType=DOWNLOAD \
     -o iowa-liquor.csv

Translate the dates, clean up numbers, pre-import

# via bash
sed -E "s#([0-9]{2})/([0-9]{2})/([0-9]{4})#\3-\1-\2#" < iowa-liquor.csv | 
  tr -d '$' > iowa-liquor-datefixed.csv

SQL

Basic MySQL schema to include all the fields; however, you can probably drop the redundant STORE LOCATION field, at the very least.

# mysql
CREATE TABLE `iowaalcohol` (
  `DATE` date DEFAULT NULL,
  `CONVENIENCE STORE` varchar(255) DEFAULT NULL,
  `STORE` varchar(12) DEFAULT NULL,
  `NAME` varchar(255) DEFAULT NULL,
  `ADDRESS` varchar(255) DEFAULT NULL,
  `CITY` varchar(255) DEFAULT NULL,
  `ZIPCODE` varchar(20) DEFAULT NULL,
  `STORE LOCATION` varchar(255) DEFAULT NULL,
  `COUNTY NUMBER` varchar(4) DEFAULT NULL,

  `CATEGORY NAME` varchar(100) DEFAULT NULL,
  `VENDOR NO` varchar(20) DEFAULT NULL,
  `VENDOR` varchar(255) DEFAULT NULL,
  `ITEM` varchar(20) DEFAULT NULL,
  `DESCRIPTION` varchar(255) DEFAULT NULL,
  `PACK` int(11) DEFAULT NULL,
  `LITER SIZE` int(11) DEFAULT NULL,
  `STATE BTL COST` float(7,2) DEFAULT NULL,
  `BTL PRICE` float(7,2) DEFAULT NULL,
  `BOTTLE QTY` int(11) DEFAULT NULL,
  `TOTAL` float(12,2) DEFAULT NULL,
  KEY `STORE` (`STORE`),
  KEY `DATE` (`DATE`),
  KEY `CATEGORY NAME` (`CATEGORY NAME`),
  KEY `CATEGORY` (`CATEGORY`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Dirty store names data

The store names aren't normalized; however, STORE seems like it should be a reliable enough foreign key for this other dataset on Socrata: Iowa Liquor Stores.

SELECT `STORE`, `NAME`, `ADDRESS`, `CITY`, `ZIPCODE`, `COUNTY NUMBER`, `COUNTY` 
FROM iowaalcohol
WHERE `STORE` = '2508'
GROUP BY `STORE`, `NAME`
Result
STORE NAME ADDRESS CITY ZIPCODE COUNTY NUMBER COUNTY
2508 Hy-Vee Food Store #1 / Cedar Rapids 1843 JOHNSON AVENUE, N.W. CEDAR RAPIDS 52405 57 Linn
2508 Hy-vee Food Store #1/ceda 1843 JOHNSON AVENUE N.W. CEDAR RAPIDS 52405 57 Linn
2508 Hy-vee Food Store #1/Cedar Rapids 1843 JOHNSON AVENUE N.W. CEDAR RAPIDS 52405 57 Linn

Top spirits by total sales

CATEGORY NAME is seemingly cleaner...here's how to get a quick summation of liquor categories, ordered by total sales, e.g. SUM(TOTAL):

SELECT `CATEGORY NAME`,
ROUND(SUM(`TOTAL` / 1000)) as `total_sales`,
SUM(`BOTTLE QTY`) AS `total_bottles`,
ROUND(SUM(`LITER SIZE` * `BOTTLE QTY` / 1000) / 1000, 2) AS `total_liters`,
TRUNCATE(AVG(`TOTAL` / (`LITER SIZE` * `BOTTLE QTY` / 1000)), 2) AS `avg_cost_per_liter`
FROM iowaalcohol
GROUP BY `CATEGORY NAME`
ORDER BY `total_sales` DESC

Note: I don't really know if I'm interpreting the BOTTLE QTY and the seemingly irrelevant PACK columns correctly.

Top selling liquors in Iowa since January 2014

Note: total_sales and total_liters are in the thousands.
