Behind the Data: Astrological signs and income
We used data from the General Social Survey to compile this data set. Income as defined by the GSS was family income (the incomes of all those related and living in a household), before tax and government transfer.
In order to ensure a large enough sample for the data set, the data on incomes and astrological signs was compiled from the years 2006-2012.
The survey asked respondents for their astrological signs. Options were: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius or Pisces.
