Percentage of large cities within each UNPD region that had an IWS program. Gray countries had no documented IWS programs and white countries had no cities large enough to qualify for inclusion in the CWM database. The remaining regions are shaded from the highest proportion of CWM cities with IWS (50%, dark green), to the lowest proportion of CWM cities with IWS ( < 10%, light green)
