Report the demographic and independent variables that are relevant to complete a demand analysis providing a rationale for the selection of the variables
Demand analysis is the research into the desire of consumers for a particular product or service. It is used to identify who wants to buy a given product, how much they are likely to pay for it, how many units they might purchase, and other factors that can be used to determine product design, selling cost, and advertising strategy for a product. The demand sensitivity analysis determines the change in quantity demanded in response to changes of any of its factors - price, income, interests,occupation, marital status, etc. Grouping of households by gross income or income per family member (it is clear that patterns of family of two and a family of six for equal wages will be different). Different composition of the family also have different requirements for the number and nature of the goods and services purchased. Finally, take into account the differences in consumption based on social, national, and other factors.
