Demographics are the statistical component of marketing used to identify population segments by specific characteristics. Business owners often first gather demographic information to include in the business plans used to raise start-up funds and guide the launching of the business. Demographic information includes geographic area, age, income, race, gender and education level. It also includes shopping habits, marital status, number of children and other information about consumer characteristics. The independent variables for this report will be population, average income per household, age of population, and the price of pizza. A key determinant of demand is the population of the area in question and as we will see in this report, growth will play a positive factor. Areas with higher income are willing to pay extra for a convenience of pizza delivery and typically hold more parties where pizza delivery is used as opposed to friends bringing food. The dependent variable is the number of pizzas sold in the area. Using a regression model we will input the dependent variable; value of pizzas sold, along with the independent variables; population, median household income and price. We then will look then look at the summary output from the regression to make some decision about bringing a pizza store to our city. the calculation of the regression analysis of the Domino’s pizza company, which is a procedure commonly used by economists to estimate consumer demand with available data, we need to collect the data: dependent and independent variables. From the dependent variables (the amount to be determined) can be demand, , population size and the independent variable can be price of pizza, income per household, price of soda.
