How was this data collected? Our regional and country personality profiles are based on aggregated and anonymized NERIS Type Explorer® results, gathered over the course of around 3 years.

How representative is this sample? Previous research into overall internet use leads us to expect Introverted, Intuitive, Feeling, and Turbulent personality types to be slightly overrepresented among our respondents. However, this has no impact on our ability to compare state, national, and regional personality profiles – due to our extremely large sample size (over 40 million respondents in total), any overrepresentation caused by the online nature of our assessment would be at the global level, affecting all regions and countries equally.
