Перевести. consumer demand is the quantities of a particular good that an individual consumer wants and is able to buy as the price varies, if all other factors influencing demand are constant.

Ну могу попробовать: "потребительский спрос - это количество определенного товара, которое данный потребитель хочет и способен купить при меняющейсяя цене, в то время как все остальные факторы, влияющие на спрос, постоянны."
