While household income takes all households into account, family income only takes households with two or more persons related through blood, marriage or adoption into account.

Purchasing power parity

Equatorial Guinea's GDP per capita is 50% higher than Australia's, yet life expectancy in Equatorial Guinea is less than 50 years and most of their citizens live in abject poverty, the vast majority subsisting on less than $1 per day.

Equatorial Guinea is a corrupt country, which helps explain why most of the people do not benefit from the oil wealth. However this issue isn't just about corruption. A comparison between median household income and GDP per capita for advanced countries is shown in Figure 2. These countries do not have serious corruption problems and yet there is only a weak correlation (R=0.16) between the two indicators. Showing that even when comparing advanced countries, differences in economic activity do not have a predictable effect on household income.
