The "ecological fallacy" is similar to Durkheim's (see Chance News 92 [http://test.causeweb.org/wiki/chance/index.php/Chance_News_92#Simpson.E2.80.99s_paradox_and_the_ecological_fallacy here] for discussion), where he noted that the more Protestant the Prussian province, the larger the suicide rate, but it turns out that the suicides were actually committed by Catholics, not Protestants.

Politics and porn (What's the matter with Kansas?)
Distrust your data
by Jacob Harris, Source (opennews.org) 22 May 2014
Harris identifies 6 ways to make mistakes in reporting data:
- Sloppy proxieson
- Dichotomizing
- Correlation does not equal causation
- Ecological inference
- Geocoding
- Data naivete
His principle example is a story that was widely covered in social media. It concerned but the biggest is related to "geocoding"
What happened here was that a large percentage of IP addresses could not be resolved to an address any more specific than “USA.” When that address was geocoded, it returned a point in the centroid of the continental United States, which placed it in the state of—you guessed it—Kansas!
The "ecological fallacy" is similar to Durkheim's (see Chance News 92 here for more discussion), where he noted that the more Protestant the Prussian province, the larger the suicide rate, but it turns out that the suicides were actually committed by Catholics, not Protestants.
