Depending on sample size, VoxIran allows subscribers to see survey results at national, regional, and provincial levels.

Each of IranPoll’s nine regions are composed of two or more Iranian provinces that are geographically, ethnically, and linguistically connected. This grouping creates an additional unit of analysis and is helpful when the survey sample size is not large enough to allow for provincial level analyses and comparisons:
