World Happiness Data Set

Data set consisting of 498 rows and 12 columns containing data from the World Happiness Report over three years.

Usage

data("happiness")

Format

data.frame() with 12 columns:

Time:

year of the World Happiness Report.

Region:

region of the world.

Country:

country.

Happiness:

happiness score measured in the respective year (see Time) by asking “How would you rate your happiness on a scale of 0 to 10 where 10 is happiest?”.

Rank:

rank of the country based on Happiness.

GDP:

extent to which the gross domestic product per capita contributed to the calculation of Happiness.

Family:

extent to which family contributed to the calculation of Happiness.

Health:

extent to which life expectancy contributed to the calculation of Happiness.

Freedom:

extent to which freedom contributed to the calculation of Happiness.

Corruption:

extent to which the perception of corruption contributed to the calculation of Happiness.

Generosity:

extent to which generosity contributed to the calculation of Happiness.

Dystopia:

extent to which the dystopia residual contributed to the calculation of Happiness. Dystopia is an imaginary country with the world's least-happy people (which can act as a benchmark against which all countries can be favorably compared).

Details

GDP, Family, Health, Freedom, Corruption and Generosity describe the extent to which these factors contribute in evaluating the happiness in each country. If added together with Dystopia, one receives the happiness score.

The data set is based on the World Happiness Report (https://www.worldhappiness.report/) and derived from the public tables provided with the report and provided by Kaggle on 2018-04-20 (historical mirrors such as Kaggle may require an account and change over time, so we refer to the official site above). Downloaded from Kaggle as three separate .csv files (one for each year), joint columns (variables) were then built, rows expanded (to be the same for each year) and sorted according to Region and Country, and Time was added to obtain a single data set.
