There are more than 5000 households in the area and most are engaged in the trade of rag-picking and daily wage earners. As the population of the area mainly comprises of migrants, no uniform language is spoken as they speak in their regional dialect. Since the migrants belong to the states of West Bengal, Bihar and Uttar Pradesh, the language most commonly spoken here are Magahi, Hindi and Bangla. All the houses in the area are pakka houses which are constructed in a cramped manner leaving no space between the adjoining houses and leaving narrow streets. Although the locality has a community centre but it lacks community recreation centres and library. Public Distribution System (PDS) is available and functions systematically in each block. While the electricity here is provided by the New Delhi Power Ltd. (NDPL), the residents have access to water supplied by the Delhi Jal Board (DJB). The locality also has a DJB office. The residents have access to medical services at Babu Jagjivan Ram Hospital apart from the various private clinics available in the locality. Moreover, every block has a dispensary each. The people here are not very educated and they are mostly labourers, rag-pickers or vegetable/fruits hawkers. But the presence of government schools and by the help and initiative of the organisations working in the locality has encouraged the parents and children alike, and many children have taken up education with prospects of a better future. At present, there are 3 government schools upto senior secondary level, while every block has a primary level government school or Nagar Nigam Prathamik Vidyalaya. For higher studies children opt for colleges in Delhi University or IGNOU. This eagerness for education has helped some families and their children who now are educated/ skilled enough to secure a respectable job and support their families. This has also led to many youth from the community itself to take up the initiative of helping the other families in the community. The issues prevailing in the colony are unemployment, poverty, illiteracy, poor health and sanitation, domestic violence, child labour, female foeticide, alcoholism, drug abuse etc.
