Disclaimer: Data points were taken from published literature (see reference list). Additional data for United States of America were kindly provided by Kohn, M., Diaz, J, and Song, Y, Rice University, Houston, US. Geographical co-ordinates were rounded to a level of uncertainty, which does not allow to conclude on addresses with confirmed resistance on the map. The center of a coloured resistance spot deviates by minimum 2km from the site of resistance sampling.
