Surveys always ask of the combined income of your household excluding tax. I’m not sure if we make 100,000 a month. My siblings are all single so they don’t have their own families so they are able to contribute to the family expenses. My father is old but he still works as a driver. My mother has no work but just plain housewife. I have a store which I’m able to earn just for myself. How many in your family shoulder the monthly expenses?
