Present circumstances

In Pakistan 
The majority of the Changars within northern and central Punjab are agricultural labourers, visiting villages during harvest time. They have established routes that they follow, and each Changar sub-group is allocated a particular village, and often serve a particular family in that village. Their patrons tend to belong to the large Muslim Jat community. In addition to agricultural labour, the Changar are also involved in the manufacture of baskets and brooms, which they sell to settled communities. Nowadays only 10% are involving in this work. Many of Shamsi (Changar) are now in good Jobs and local business after getting education. In local Government they have their own Counselors and have Chairmanship.
