Income is a key component of an household economic wellbeing. According to the Australian Bureau of Statistics, transport is the highest household expenditure after housing costs and food and non-alcoholic beverages, accounting for 16% of total household income. Income is also an important socio-demographic variable that influences travel behavior and residential location choice patterns.
In this project, we are visualizing the spatial distribution of household income in greater Melbourne area. We use Census data from 2011. Household income is derived from personal income information collected for all persons aged 15 years and over. It includes all wages and salaries, government benefits, pensions, allowances and any other income before deductions for tax, superannuation, health insurance, salary sacrifice, or any other deduction.
We group the population into four groups. Households earning $0-$399 weekly account for about 13% of the number of households live in the greater Melbourne area. About 19% of households earn more than $2500 weekly. The rest of the households (representing lower and upper middle class families) are grouped into two groups, earning $400-$1249 and $1250-$2499 weekly.
The project is funded by the Faculty of Engineering Seed Funding and the Immersive Analytics Project at Monash University.
