A Summer of Learning: Tableau Part 2

2017-06-08_10-07-16

Last week I looked at some of the first Tableau visualizations I made as part of my summer short classes at Indiana University. This week the data I want to examine is the World Development Indicators about Energy from the World Bank Development Indicators with the most recent data being from 2014. It presents the most current and accurate global development data available, and includes national, regional and global estimates.

Three countries in the Middle East were chosen for analysis: Afghanistan, Iran and Pakistan. The following attributes were selected: Population Growth, Access to electricity, Access to clean fuels and technologies for cooking, and Renewable Energy Use as a Percentage of Total Energy Use. All of the attributes units were percent of population.

The data was preprocessed from the raw data to delete the “Country Code” and “Series Code” columns. Additionally, all null values were deleted and the field names were renamed as aliases.

You can see all of my Tableau visualizations to date at https://public.tableau.com/profile/the.data.lass#!. The first tab shows the average population growth in Afghanistan, Iran and Pakistan in 2014. Afghanistan has the highest growth of its other two neighbors at 3.03%. The second tab shows the percentage of population that has access to clean fuels and technologies for cooking for Afghanistan, Iran and Pakistan in 214. Under World Health Organisation guidelines, kerosene is excluded from clean cooking fuels. Accelerating efforts to increase access to clean, modern cooking fuels is essential for achieving the Sustainable Energy for All (SE4All) goals. Note that Pakistan uses about six times more clean cooking fuel (30.22%) than its neighbor Iran (5.22%). The third tab shows the percentage with electricity access in Afghanistan, Iran and Pakistan in 2014. Afghanistan has the lowest access with 89.5%. The fourth tab shows the percent of Electricity that is renewable by country in 2014. Note the large difference between Pakistan (47.21%) and its neighbor Iran (0.94%). Now that we’ve compared each of the WDI’s within each country in 2014, we want to explore any trends that may have occurred over time.

The fifth tab shows a snapshot over time of the percentage of the population using clean fuel or technology for cooking in Afghanistan, Iran and Pakistan. In Afghanistan, the amount decreases steadily from 21.76% in 2003 to 17.31% in 2014. There is no real trend in Iran. In Pakistan, the highest amount of 33.7% was in 2010. The sixth tab shows a snapshot over time of the population’s access to electricity in Afghanistan, Iran and Pakistan. Afghanistan’s percentage access to electricity increased dramatically from 7.2% in 2003 to 89.5% in 2014. Pakistan’s access increased from 79.9% in 2003 to 97.5% in Iran’s access increased very slightly from 98.08% to 99.44%. Finally, the seventh tab shows a snapshot over time of the percent of electricity that is renewable in Afghanistan, Iran and Pakistan over time from 2003-2014.Note the decrease over time in Afghanistan from 2004 (49.19%) to its lowest at 10.79% in 2011. Iran uses almost no renewable energy while its neighbor Pakistan uses significantly more.

In the next blogs, I’ll switch gears a bit and talk about my other two summer courses: mySQL and R.
