The idea of want can be examined from many perspectives. In secular societies want might be considered similar to the emotion desire, which can be studied scientifically through the disciplines of psychology or sociology. Want might also be examined in economics as a necessary ingredient in sustaining and perpetuating capitalist societies that are organised around principles like consumerism. Alternatively want can be studied in a non-secular, spiritual, moralistic or religious way, particularly by Buddhism but also Christianity, Islam and Judaism.
In economics, a want is something that is desired. It is said that every person has unlimited wants, but limited resources (economics is based on the assumption that only limited resources are available to us). Thus, people cannot have everything they want and must look for the most affordable alternatives.
Wants are often distinguished from needs. A need is something that is necessary for survival (such as food and shelter), whereas a want is simply something that a person would like to have. Some economists have rejected this distinction and maintain that all of these are simply wants, with varying levels of importance. By this viewpoint, wants and needs can be understood as examples of the overall concept of demand.
Examples of wants that people would like to have is financial monitoring, saving time, higher paying job, more comfort, healthier diet, physical fitness, spirituality, friendship, companionship and safety.
