Chapter OneFactors influence consumer behavioral differences between US big cities and small citiesHow and why do factors influence the consumer behavioral differences between US big and small cities? Has it consumer behavioral differences between US big and small cities? I shall indicate some evidences to attempt to explain whether it is possible that the consumer behavioral differences between US big and small cities as below: For cosmetic product sale industry example, whether it has consumer behavioral differences between US big and small cities to influence US big and small cities residents whose consumption use for personal purpose. The major factors of cosmetic facial beauty product of price, attractive packing, sales promotion, advertisement, ingredients and warehouse storage factors will influence the US big cities and small cities resident consumers' attitudes and choice consumption behavioral differences. It is due to the sale method difference of sale price, ingredients, promotion method and warehouse storage number to cosmetic products when the cosmetic consumers choose to buy any brands of cosmetic products from small cities or big cities in US.In fact, cosmetics are not just used by the US young female resident customer any longer, US young male resident customer is increasing taking as the use of more and more body sprays, perfumes and other cosmetics. Hence, the US resident young female and male both young cosmetic product buyer number will influence the cosmetic product sale number in US big and small cities. For example, if the US big or small cities have many adult older age male or female residents are living more than the younger age male or female residents in US. Then, the US resident cosmetics consumer will reduce. Otherwise, if US big or small cities have many US younger age male or female residents are living more than the older age. Then, the US itself US resident cosmetics consumer number will raise in possible. The reason is because cosmetics product need is depended on age factor. So, younger age US big or small cities residents will have more facial beauty need to more than older age US residents who is living in either US big cities or small cities. Such as US cosmetic product sale case, the large or small cities cosmetic product sale number will be extremely depended on whether how any younger or older age US residents who are living in the either big or small cities in US.Based on this age factor reason, the age factor is more important to influence US big or small cities cosmetic product sale number more than other factors, such as price, brand, promotion ingredients etc. different cosmetic products themselves basic product sale method factors. Also, it implies that the US large or small cities cosmetic facial beauty product sale number will not be possible to be influenced the sale number to be reduces, even the brand of cosmetics product sale price is raised, if the US large or small cities have many younger age US residents are living more than older age US residents number who are living in US. Hence, in consumer behavioral view point, it seems to explain that the age factor is extremely important to influence the US big cities or small cities cosmetics product sale number.Another one for luxury fashion sale industry example, whether it has consumer behavioral differences between big cities and small cities in US. In fact, luxury fashion industry, it has low or high luxury quality difference. This quality factor will influence US resident consumption behaviors between big cities and small cities in US.
