They are classified into two groups.
1. Basic human needs – This are things one cannot do without e.g.food. They always come at the top for the scale of preference and failure to satisfy them one can lead a miserable life or even die.
2. Secondary human wants – they are things one cannot do without. They help one lead a happy meaningful and comfortable life e.g.TV set, radio, cars, education, sodas etc.
NB. one must satisfy basic needs before attaining secondary wants.
Since the resources to satisfy human wants are scarce, one has to select on what wants are to be satisfied first and which can wait.
