Variable Descriptions

1. Country (Nominal) - the country in which the indicators are from (i.e., United States of America or Congo)
2. Year (Ordinal) - the calendar year the indicators are from (ranging from 2000 to 2015)
3. Status (Nominal) - whether a country is 'Developing' or 'Developed' by WHO standards
4. Life_expectancy (Ratio) - the life expectancy of people in years for a particular country and year
5. Adult_mortality (Ratio) - the adult mortality rate per 1000 population (i.e., number of people dying between 15 and 60 years per 1000 population); if the rate is 263 then that means 263 people will die out of 1000 between the ages of 15 and 60; another way to think of this is that the chance an individual will die between 15 and 60 is 26.3%
6. Infant_deaths (Ratio) - number of infant deaths per 1000 population; like above, but for infants
7. Alcohol (Ratio) - a country's alcohol consumption rate measured as liters of pure alcohol consumption per capita
8. Percentage_expenditure (Ratio) - expenditure on health as a percentage of Gross Domestic Product (GDP)
9. Hepatitis_b (Ratio) - number of 1-year-olds with Hepatitis B immunization overall 1-year-olds in the population
10. Measles (Ratio) - number of reported Measles cases per 1000 population

14. Total_expenditure (Ratio) - government expenditure on health as a percentage of total government expenditure
15. Diphtheria (Ratio) - Diphtheria tetanus toxoid, pertussis (DTP3) immunization rate of 1-year-olds
16. HIV/aids (Ratio) - deaths per 1000 live births caused by HIV/AIDS for people under 5; the number of people under 5 who die due to HIV/AIDS per 1000 births
17. GDP (Ratio) - Gross Domestic Product per capita
18. Population (Ratio) - population of a country
19. Thinness_1-19_years (Ratio) – the rate of thinness among people aged 10-19 (Note: variable should be renamed to thinness_10-19_years to represent more accurately the variable)
20. Thinness_5-9_years (Ratio) – the rate of thinness among people aged 5-9
21. Income_composition_of_resources (Ratio) - Human Development Index in terms of income composition of resources (index ranging from 0 to 1)
