Survey Methodology

Stasis conducts surveys over the telephone using a proportional two-stage sampling method. In stage one, a pre-determined number of random respondents (depending on the survey’s sample size) will be selected from a database of more than 130 million geo-tagged numbers and stored in the Stasis’ proprietary software, icATI. These contacts will be chosen from among all the cellphone carriers in Iran, proportionally categorized by province population. In Stage two, the icATI software randomly assigns a list of potential respondent contacts from that pool to each interviewer. Interviewers make contact via telephone and report their results on the platform. After conducting the questionnaire and reporting the results, each specific telephone contact will be confirmed as a valid response in the platform.  This process continues until we receive the adequate number of samples for the given project.

The results of each poll are then visualized in an interactive platform that details the results of every question distinguished by gender, age group, location, and education in a bar chart.

For each question, there is also a bubble chart (consisting of many small circles), that is populated with the individual respondent’s information. Clicking on a bubble will pull up the complete answer set for that respondent. The color coding is consistent between the bubble chart and bar chart for easy comparison.

Results are usually weighted by gender, age, and location (urban vs. rural areas) based on the Iranian national census of 2016 and 2018 statistical yearbook.

After conducting each survey, the questionnaire and the full report will be accessible through the platform. Stasis also publishes the raw data within six months of conducting each poll.
