This is an incredibly interesting Tweet. The graph below shows Gini of Household per capita income around 2013.

It might sound an obvious point to make, but it is hotly debated whether the distribution of labour income impacts on inequality.
Note: Using the UK spelling of Labour – because that is what we use in South Africa.
