1. Topic
Alcohol permeates every aspect of life in the United States. Whether it’s a work party, a
night out with friends, a sporting event, or many other events and celebrations, there is no way to
not be surrounded by drinking.
In this computer project the comparison between consumption of all types of alcohol will be
analyzed and the investigation of a possible relationship between three variables will be
explained.
I chose this topic because the ethical dilemmas surrounding alcohol fascinates me. Are you
responsible for your actions when you are under the influence? I was also interested to know if
the income of someone can affect the amount of alcohol was consumed. On the one hand, people
often use alcohol as a coping mechanism and could possibly be used by the poor to cope with the
less than ideal conditions they experience. However, people who have a higher income often
have more excess money to spend past food and housing that can be used to buy alcohol.
My hypothesis is that the consumption of alcohol per capita is proportional to the Gross
National Income (GNI) per capita and proportional to the taxes paid by the people as a percent of
the Gross Domestic Product (GDP). This correlation will be checked and discussed in this
project.
One hundred and eighty-eight countries had data, but only one hundred and thirteen countries
had all the needed data to be analyzed.
This is a relevant topic because the amount of alcohol consumed by one person can be
dangerous to others. Drunk driving and other risky behaviors can surface when people are under
the influence. The amount of alcohol consumed per capita by a country can be helpful to know in
order to protect yourself when travelling.
2. Background Description
Alcohol has been prevalent in society since before the written records of history. The
fermentation of alcoholic drinks can be traced back at least 10,000 years ago to prehistoric
times. The first types of alcohol were most likely fermented berries or honey.
In the ancient world, wine appeared in Egyptian pictographs around 4000 BC. The
Hebrews began drinking wine during their captivity in Egypt. Laborers were also given beer
and provided nourishment and calories. The Mayans fermented corn or maize to make mead.
Alcohol was already being consumed all over the world.
The Romans were well known for abusing alcohol. Wine was distributed very cheaply
in order to placate the empire that was experiencing major decline and immigration. Jesus used
wine in his teachings and approved wine in moderation. It’s abuse, however, was seen by the
church as a sin. When the Huns invaded Europe, the production of wine dropped dramatically
as they ravaged vineyards and cellars. Alcohol permeated the Viking culture and they saw
heaven as a place where you could drink endless amounts of alcohol. Wine was very expensive
and so commoners could not afford it, but towns in countries like Germany began to be able to
brew their own beer.
In the Middle Ages came the discovery of distillation of alcohol to be used as
medication. Brandy was first known as aqua vitae, or the water of life. At this point, beer
consumption in countries such as Bavaria was about 300 liters per capita a year.
The Puritans in 1620 brought more beer than water on the Mayflower and landed on
Plymouth because their supply of beer was running low. Brewing beer was one of the first
productions for the colonies.
While the Catholic and Protestant churches believed that only drinking in excess was a
sin, Muslims believed that drinking any amount of alcohol was unacceptable.
Around the 17th century, the first grain spirit, Whiskey, is believed to have been
invented in Ireland or Scotland. At this point, however, spirits were still mainly for medicinal
purposes. It wasn’t until the sugar production in the Caribbean enabled the production of
molasses for rum and used in the Triangle Trade route that spirits became popularized.
After the 1870s, alcohol consumption began to decline. Historians are unsure exactly
why this trend happened, but factors such as other caloric food availability and the temperance
movement are said to be possibilities. Protestant churches began to reject alcohol in any
quantity. Prohibition of alcohol swept the world as Russia, Hungary, Norway, Iceland, the
United States, Canada and many other countries set up the new law to stop the production of
alcohol. However, this created more social problems than fixing them.
Studies in the 1970s on the consumption of moderate amounts of alcohol found it to
actually have positive benefits to health. Since then, the taxes of alcohol have increased, the
drinking age has risen, punishments for alcohol-related accidents has become much stricter,
and there are more restrictions on the advertising of alcohol.
But the danger of drinking has increased since the beginnings of time. When people
were consuming double the amount of alcohol we do today, their only transportation was at
most a horse. Now, our transportation can reach even deadlier and more dangerous speeds than
ever before. Additionally, although the prevalence of alcohol might not have increased since its
peak in the 18th and 19th centuries, we are now in a world of constant communication. Before,
alcohol could be out of sight, out of mind. But today’s world causes us to constantly be
bombarded by messages, whether we want to hear them or not. This means that something as
addictive as alcohol could be constantly shown to us in order to convince us to buy and drink it
in excess, making it feel even more prevalent today than ever before. The restrictions on
alcohol seek to ameliorate these problems. (Boyle, 2013)
After some research, I found some similar studies to mine. The first studied 6894
persons in Norway, and asked them to self-report their socio-economic class and amount of
alcohol consumed. The study spanned from 1993 to 2000. They found that consumption of
alcohol increased from year to year, and that the consumption of alcohol increased based on
lower income and education level. It was also found in this study that if you were male, you
were more likely to drink more than if you were a woman (Strand, 2000).
Another study that I found that was similar to mine was a study in the Netherlands. In
1991, researchers studied whether there was a correlation between excessive drinking and
stressors such as financial problems, deprivation, and income. They defined excessive drinking
as “drinking more than six glasses on 3 or more days a week or more than four glasses on 5 or
more days a week” (Droomers, 1999). They also studied how educational level affected
drinking level. They found that excessive drinking was more common among people with
lower educational levels and the prevalence of the stressors.
Other than that, I was surprised that I didn’t find any more studies that were related to
mine. I researched on Google Scholar to find related studies. While there were many on the
topic of alcohol, it was alcohol and a variable other than income or anything related that was
studied with it.
Alcohol has been prevalent in society since the beginning of time, and in no way is
going away anytime soon. Understanding the reasons why alcohol is more prevalent in certain
countries, and which countries it is most prevalent in, is essential to not only ensure safety
when traveling, but also to begin to understand this ancient drink.
3. The Scope of the Project
The main purpose of this project is to explore, analyze, and describe the data set of the
alcohol consumption per capita in 2013, which is measured by how many liters of all types of
alcohol are consumed per capita. In this research, numerical, graphical, and tabular methods
will be used to analyze the chosen data set. The aim of my report is to understand how certain
factors can affect the amount of alcohol that is consumed by people in different countries.
The secondary objective of my project is to compare alcohol consumption in the world in
2009 and 2013. Measures of central tendency and measures of difference will be used to
discover if my hypothesis is true or not.
4. Data Source
The source of the data is http://apps.who.int/gho/data/node.main.A1026?lang=en given by
the World Health Organization. Data in the tables are those available from 2000 to 2015 and
was last updated on September 29, 2016. This is cross-sectional data. The data is recorded
from 186 countries.
The other sources of data are http://data.worldbank.org/indicator/NY.GNP.PCAP.CD for
the GNI per capita (cross-sectional data recorded in 146 countries) and
https://stats.oecd.org/Index.aspx?DataSetCode=REV for the tax revenue (cross-sectional data
recorded in 161 countries)
5. Statistical Analysis
Numerical Methods:
As Table #2 indicates:
1. A typical country in the world is expected to have an alcohol consumption of 5.70 liters
per capita per year.
2. The bottom 50% (half least alcohol consuming) of the countries consume less than 5.87
liters of alcohol per capita per year and the top 50% (half most alcohol consuming) of
countries consume at least 5.87 liters of alcohol per capita per year.
3. The most observed alcohol consumption per capita was .01 liters per year-in the world
of 113 countries, 2 countries had this value for consumption.
4. The actual consumption of alcohol per capita per year is spread from the expected value
by a measure of 3.89.
5. The data is moderately flat (-.99)
6. The data is slightly skewed to the right (.18)
7. Lithuania’s consumption of alcohol per capita per year exceeds Afghanistan and
Bangladesh’s consumption by 15.03 liters.
8. The least alcohol consumed by a country per capita per year was .01 liters by
Afghanistan and Bangladesh
9. The most alcohol consumed by a country per capita per year was 15.04 liters by
Lithuania
10. The total consumption of all countries is 638.42 liters per capita in 2013
11. There were 113 countries in the world in 2013 with available data for alcohol
consumption.
12. The bottom quarter of countries consumed less than 1.88 liters of alcohol per capita per
year. The top three-quarters of countries consumed more than 1.88 liters of alcohol per
capita per year.
13. The top quarter of countries consumed more than 8.94 liters of alcohol per capita per
year. The bottom three-quarters of countries consumed no more than 8.94 liters of
alcohol per capita per year.
14. The middle 50 percent of countries’ consumption differs by 7.07 liters per capita per
year. One-fifth of countries have a consumption of less than 1.55 liters.
15. Four-fifths of countries have a consumption of more than 1.55 liters.
16. One-third of countries have a consumption of less than 3.20 liters. Two-thirds of
countries have a consumption of more than 3.20 liters.
17. Two-thirds of countries have a consumption of less than 7.56 liters. One-third of
countries had a consumption of more than 7.56
18. 90 percent of countries had a consumption rate of at most 10.62 liters per capita per
year. 10 percent had a consumption rate of at least 10.62 liters.
6. The standard deviation is 66 percent of the mean
Table #3 shows changes of consumption rate of countries between 2009 and 2013
Table #2 indicates kurtosis (-.99) and skewness (.18). The alcohol consumption rate
distribution is moderately flat. The alcohol consumption rate distribution is skewed slightly to
the right- toward the large alcohol consumption rate of country #62 (Lithuania).
Interpretation of Z Score
Mean = 5.70, Standard Deviation = 3.89.
Afghanistan/Bangladesh .01
Z = (.01-5.70)/3.89 = -1.46
The consumption of alcohol in Afghanistan and Bangladesh is 1.46 standard deviations below
average
United States 5.82
Z = (5.82-5.70)/3.89 = .03
The consumption of alcohol in The United States is .03 standard deviations above average.
Lithuania 15.04
Z = (15.04-5.70)/3.89 = 2.40
The consumption of alcohol in Lithuania is 2.40 standard deviations above average.
Application of the Chebyshev’s theorem
Mean = 5.70, Standard Deviation = 3.89.
Z=1.2; ( Z * σ ) = 1.2 * 3.89 = 4.67
Z=1.5; ( Z * σ ) = 1.5 * 3.89 = 5.83
Z=2.3; ( Z * σ ) = 2.3 * 3.89 = 8.95

2.3 5.70 + - 8.95 -3.25 14.65
Z=1.2; (1 – 1/Z*Z) = (1 – 1/(1.2)*(1.2)) = .3056
Z=1.5; (1 – 1/Z*Z) = (1 – 1/(1.5)*(1.5)) = .5556
Z=2.3; (1 – 1/Z*Z) = (1 – 1/(2.3)*(2.3)) = .8110
At least 30.56 percent of countries consume between 1.03 liters and 10.37 liters of alcohol
At least 55.56 percent of countries consume between -.13 liters and 11.54 liters of alcohol
At least 81.10 percent of countries consume between -3.25 liters and 14.65 liters of alcohol
Empirical Rule
The distribution of my data set was almost normal distribution, but the empirical rule is used.
Low End High End

Approximately 68 percent of countries’ alcohol consumption is between 1.81 liters and 9.59
liters per capita per year.
Approximately 95 percent of countries’ alcohol consumption is between 0 liters and 13.48
liters
Almost all of countries’ alcohol consumption is between 0 liters and 17.37 liters

Graphical Methods:
a. Graphical Measures
Interpretation of the graph #1 (The Bar Graph)
The graph is asymmetrical and unimodal
Graph #1 shows that the most frequent category is 0-1 liters of
alcohol and the second most frequent category is 1-2 liters of alcohol
Interpretation of the graph #2 (The Area Chart)
The alcohol consumption relative distribution is moderately skewed
to the left toward the lower consumption of alcohol.
The alcohol consumption distribution is moderately flat.
The most observed consumption of alcohol in 2013 was .1-out of 113
countries, 2 countries had a consumption of .1
Interpretation of the graph #3 (Pie Graph)
13.51% of countries fell in the category 0-1 liters of consumption of
alcohol consumed, the most common category. The least common
categories, making up .9% of the data each, was 2-3 and 14-15 liters.
The bulk of the data is clustered around countries with consumptions
0-2 liters and 5-10 liters.
Interpretation of the graph #4 (Stem and Leaf Display)
A Stem and Leaf Display is a graphical method of displaying data
It is not useful for my data because my data is too numerous and the
range of my data is too small.
Interpretation of the graph #5 (Ogive)
86% countries had an alcohol consumption of at most 10 liters
44% countries had an alcohol consumption of at most 5 liters
34% countries had an alcohol consumption between 5 and 10 liters
14% countries had an alcohol consumption of at least 10 liters
Interpretation of the graph #6 (Box and Whisker Plot)
The IQR of the data is skewed slightly to the left of the median
There are no outliers.
Interpretation of the graph #7-8 (Box and Dot Plots)
The bulk of the data is clustered between 0-2 liters and 5-10 liters
b. Graphical Mesaures of Relationship –Visualization Step
Interpretation of Graph #8 “Scatter plot of the relationship between Alcohol Consumption
2013 and GNI in 2009”:
Alcohol Consumption (Y) and GNI 2009 (X1) seem to be slightly related in a direct linear
fashion. Between $0-$20,000, there seems to be no relationship between the data. However,
after $20,000 there seems to be a direct linear relationship between X and Y.
Interpretation of Graph #9 “Scatter plot of the relationship between Alcohol Consumption
2013 and GNI in 2013”
Alcohol Consumption (Y) and GNI 2013 (X2) seem to be slightly related in a direct linear
fashion. Between $0-$20,000, there seems to be no relationship between the data. However,
alike to Graph #8, after $20,000 there seems to be a direct linear relationship between X and Y
Graph #10 “Scatter plot of the relationship between Alcohol Consumption 2013 and % of
Taxes of GDP in 2013”
Alcohol Consumption (Y) and % of Taxes of GDP (X3) seem to be related in a direct linear
fashion. In comparison to Graph #8 and #10, this relationship between x and y is much
stronger.
II. Tabular Methods:
a- Frequency , Relative Frequency, Cumulative Frequency and the Relative
Cumulative Frequency Distribution Tables.
As table #6 indicates:
1. The most prevalent alcohol consumption category was 0-1 liters. 15 countries
had an alcohol consumption between 0 and 1 liter.
2. The second most prevalent alcohol consumption rate category was 1-2 liters.
13 countries had an alcohol consumption between 1 and 2 liters.
3. The third most prevalent alcohol consumption category was 9-10 liters. 11
countries had an alcohol consumption between 9 and 10 liters.
4. The lowest category of alcohol consumption frequency exceeds the highest
category of alcohol consumption frequency by 14.
5. The most common relative frequency was .05 and .07. Both of these relative
frequencies occurred three times in the table.
6. The relative frequency of 0-1 liters is double that of 3-4 liters, 5-6 liters, and 6-
7 liters.
7. 74 countries had an alcohol consumption of 8 liters at most-the middle of the
range of data categories.
8. A quarter (25.23%) of the countries’ alcohol consumption is less than 2 liters
per capita per year.
9. A little over half (51.35%) of countries’ alcohol consumption is at most 6 liters
per capita per year.
10. The difference between one quarter and halfway point of the cumulative data is
4 liters, and the difference between the halfway point and the three quarters
point of the cumulative data is 3 liters.
b- Tabular Mesaures of Relationship – Cross tabulation
As Table #8-11 indicates:
There is a direct linear relationship between consumption of
alcohol 2013 and the percent of taxes of the GDP. The most
common category was an alcohol consumption between 3-4 liters
and a 10-20% of the GDP. This occurred 6 times. The data for 0-1
liters had at most 30% taxes of the GDP. The data for 14-15 liters
and 15-16 liters had 20-30% in taxes, the middle category. 37.8%
of countries have 10-20% taxes of GDP. This is the most common
category. Noting these observations, the direct linear relationship
isn’t perfect, but there is definitely a correlation between these
two data sets.
7- Exploration of Possible Changes .
As Table #3 indicates, from 2009 to 2013:
1. The typical countries’ alcohol consumption deteriorated by 1%
2. The alcohol consumption of the top 50% of countries improved by .045 of a
liter.
3. The most frequent alcohol consumption stayed the same at .01 liter
4. The spread of actual data increased by 8% around the expected value
5. The data distribution became 26% more flat
6. The data is more skewed to the left by 6%
7. The range of data decreased by 95%
8. The minimum stayed the same at .01 liter
9. The maximum improved by .95 liters
10. The total alcohol consumption of the world deteroriated by 1.66 liters.
8- Discussion of the Possible Outliers – In my data set, I found no outliers in my data.
VARIABLE A
IQR 7.0650
1.5 * IQR 10.5975
3.0 * IQR 21.1950
Outer Fence -19.3175
Inner Fence -8.72001- Very First small # that is NOT an Outlier
.01 (Bangladesh and Afghanistan)
2- First Quartile 1.8775
3- Median 5.865
4- Third Quartile 8.94255- Very First large # that is NOT an Outlier
15.04 (Lithuania)
Inner Fence 19.5400
Outer Fence 30.1375
All of my data fits within the inner and outer fences, so there are no outliers
9. Limitations of the StudyData availability limited the elements available in my study. There were many countries
that had certain variable that had no data, and so the initial 193 countries had to be
trimmed down to 111.
In my research, 76 countries did not have all the data needed for every variable and so
were omitted from the study. The countries are as follows:
AndorraAngolaAntigua and BarbudaBeninBhutanBotswanaBrunei DarussalamBurundiCote d'IvoireCabo VerdeCambodiaCameroonCentral African RepublicComorosCongoCook IslandsDemocratic Republic of the CongoDjiboutiDominicaEritreaEstoniaFijiGambiaGhanaGrenada

10-Conclusion, Summary, and Policy Recommendations – In my research paper, the comparison of alcohol consumption per capita showed that
Lithuania was the highest drinking country in the world and Afghanistan and Bangladesh
were the lowest drinking countries in the world. After breaking the consumption into low
consumption, average consumption, and high consumption, I found that European
countries such as Denmark, France, and Finland had high consumption rates. The Middle
Eastern countries such as Egypt, Afghanistan, and Israel had low consumption rates. The
distribution of data was slightly skewed to the right.
My hypothesis was that there will be a direct linear correlation between alcohol
consumption and gross domestic income and between alcohol consumption and the
percent taxes are of the GDP. In my research, I found a medium direct linear correlation.
Therefore, my hypothesis is correct that there is a relationship between these variables.
The comparison of alcohol consumption between 2009 and 2013 found that although
the total alcohol consumption of the world deteriorated by 1.66 liters, the alcohol
consumption of the top 50 percent of countries improved by 4% and the maximum
consumption improved by .95 liters.
Alcohol is one of the oldest and most often abused drugs in our world. It is essential to
not only know the consumption of alcohol globally to protect yourself when going on
international travel, but also to understand our world today, yesterday, and tomorrow.
