Mapping Election Fraud in Afghanistan

This page shows some figures and maps about the extent of vote rigging in the 2009 presidential election in Afghanistan.

Background: The units of analysis for the results below are polling stations. Stations were set up for a maximum of 600 voters each and belong to polling centers, which are located in provinces. Rather than votes for individual candidates, I analyze voting station turnout.

Method: Evidence of fraud was established according to Beber and Scacco's last digit method, which tests for deviations from a uniform distribution of the last digits in election results (turnout, in my analysis). In an unmanipulated election, the last digits 0 through 9 should occur with equal frequency. However, this is not the case for many provinces in Afghanistan. For example, this plot shows the distribution of last digits for polling station turnout across stations in the Helmand province. Clearly, the digit zero occurs much more frequently than any other. A chi-square test can be used to find out whether the observed frequencies of the last digits deviate significantly from the uniform.

The patterns identified can be compared to the criteria employed by the Electoral Complaints Commission of Afghanistan (ECC), see maps 2 and 3 below.
