Natural Factors:
Seasonal variations may affect the demand for a commodity at certain times of the year. For example, during the raining season, demand for commodities such as jackets, raincoats and umbrellas will increase while during the dry season, demand for commodities such as fans and air conditioners will rise.
Availability of credit
When consumers are given credit facilities in the form of credit purchases, hire purchases and the use of credit cards and cheques, they are encouraged to buy more goods. Granting credit facilities, therefore, increased demand for goods covered by these facilities, all things being equal.
