Introduction to Election 2017 Atlas

Analyzing elections, political and social analysts often ask how each candidate’s vote share is driven from various social groups. Analysts usually try to understand how which electoral campaign targets which social strata.

Atlas of Iran's 2017 Presidential Election provides a set of choropleth maps that show geographical distribution of each candidate's actual votes and vote percentage at the level of province as well as county. It also tries to demonstrate possible correlation of vote share to the vote turnout and other demographic indices. We use scatter plots to demonstrate the correlation of specific social indices with each candidate's voting percentage, the voter turnout and its change from previous (presidential) election in each county.

Here is the list of the indices used in this analysis: - Total population, urban population, household size, voter turnout in 2017, turnout change from previous election (2013), and the difference in winner's voting percentage since 2013.

In every scatter plot, each point represents a county, having a radius proportional to square root of its populations, and x and y values demonstrating the explanatory and response variables, respectively.
