New analysis by a team of linguists and computer scientists at the University of Pennsylvania suggests a person's Twitter history can accurately pinpoint his or her income bracket. In scanning Twitter profiles for words indicating a person's occupation, researchers corralled 5,191 Twitter handles and more than 10 million tweets to study.

Insights confirmed previous research, that certain words and phrases reveal a person's age, gender and other social data, and that these cues can be pieced together to accurately predict a person's income.
The analysis also showed that lower-income tweeters tend to use more swear words, while higher-income tweeters were more likely to discuss politics and business.
Other patterns were more surprising: lower-income users tended to be more optimistic, while higher-income tweeters expressed anger and fear more frequently.
The analysis also offered a wide-angle view of how people from different income levels use Twitter.
"Lower-income users or those of a lower socioeconomic status use Twitter more as a communication means among themselves," Preotiuc-Pietro said. "High-income people use it more to disseminate news, and they use it more professionally than personally."
