Using an iPhone or an iPad is a good indicator that someone has a high income, according to new research.
The two Apple mobile devices were found to be one of the most common wealth status symbols of all brands and products, University of Chicago economists Marianne Bertrand and Emir Kamenica, concluded.
The researchers analysed trends in differences between groups of people, including income, education, gender, race, and political ideology. If the respondent said they owned an iPhone, this gave the researchers a 69.1 percent chance of determining the person had a "high income" and were in the top quartile for income. An iPad gave similar results with a 66.9 percent chance while owning an Android smartphone was in fourth place at 59.5 percent.
The results differed markedly in a similar study released in 1992, which found that owning an automatic dishwasher was the strongest indicator of wealth. Owning a garage door opener was another positive indicator for affluence.
"Across all years in our data, no individual brand is as predictive of being high-income as owning an Apple iPhone in 2016," the researchers said.
