An important aspect of Punjabi ethnicity is reciprocity at the village level. A man's brother is his friend, his friend is his brother, and both enjoy equal access to his resources. Traditionally, a person has virtually free access to a kinsman's resources without foreseeable payback. This situation results in social networks founded on local (kinship-based) group needs as opposed to individual wants. These networks in turn perpetuate not only friendly relations but also the structure of the community itself. There is great social pressure on an individual to share and pool such resources as income, political influence, and personal connections. Kinship obligations continue to be central to a Punjabi's identity and concerns. Distinctions based on qaum remain significant social markers, particularly in rural areas.
