Researchers out of London were able to analyze over 2 million social media posts on the Nextdoor App and accurately figure out how much the person was making.
Lead researcher, Dr. Ignacio Castro said, quote, “Our study shows that the text posted by users in poor neighborhoods is distinguishable from the text generated in wealthier neighborhoods."
A news release of the study said,
"The findings of the study also show that people who live in wealthier neighbourhoods were more likely to share positive posts but would discuss crime more, even if the actual crime rates are lower than in poorer neighbourhoods."
