Adifferent group of people who share similar needs is called an

Assistance group

Explanation:

Assistance group exist when, in a given set of different people, there are stable relations, due to common goals, needs and interests, as well as feelings of group identity developed through continuous contact.

Also, it is important to note that the group exists even if it is not close to the components. Proof of this lies in the fact that when we leave the last class of the week, although we are far from those who make up our room, the class itself does not fall apart, still existing as a group. In the same way, we can think this for our families, which corroborates the fact that the group is an intermental reality, that is, even if individuals are far away, the feeling of belonging within the consciousness of each one remains.
