With regard to leisure, it is obvious that a couple is more likely to use their money for on this necessity than a single one, 202 compared to 140. Similarly, this pattern can also be witnessed in terms of health, with 177 for a couple and 122 for a single person. Furthermore, the record of food for a pair doubles that of a single person, standing at 100 and 50, respectively.
Moving to housing, a single person allocates a comparable amount of money on this basic need, in comparison to that of a pair, with 184 and 194, in turn. Similarly, a single person and a pair share identical investment in transport, standing at around 107. Besides, while a pair allocates 80 for clothing and 70 for others, a single one uses only 44 for the former and 37 for the latter. Eventually, the total expense of a pair of Australians stands at 931$, which outnumber that of a single person, at 684$.
