The mapped voronoi polygons show polling center coverage according to population. Each polling station can accommodate up to 600 people in one day. Since 53.7% of the population votes, every 1,155 persons would need one polling station. Polygons are accordingly colored orange or blue shades depending on whether the center's polling stations accommodate more or less than 1,155 people, respectively.

About the Data

Polling Centers

Data is from the Independent Election Commission of Afghanistan.

Each pixel value in the Worldpop raster layer represents one person. So the resulting voronoi polygon has a sum that adds all values for pixels contained in that polygon, a mean for all pixel values, and a count of all pixels contained in the polygon.

This combined vector layer is saved in sqlite, where the number of people per polling station is found with a SQLite query that divides the total population per polygon (the sum of pixel values in each polygon) by the number of polling stations in that polygon.

Each polling station can accommodate up to 600 people in one day. Since 53.7% of the population votes, every 1,155 persons would need one polling station. Polygons are accordingly colored orange or blue shades depending on whether the centerâ€™s polling stations accommodate more or less than 1,155 people, respectively.
