South Asian Americans, who trace their ancestry to India, Pakistan, Bangladesh, Sri Lanka, Bhutan, Nepal, the Maldives and the South Asian diaspora, are one of the fastest growing populations in the U.S. With large concentrations in cities like New York, Los Angeles, Washington, D.C. and Houston, its no surprise that these communities have built active organizations that address a wide range of concerns. From discrimination to housing, here are five organizations that are fighting to make a difference.

DRUM (Desis Rising Up And Moving)

Founded in 2000, DRUM addresses issues facing South Asian low-wage immigrant workers and youth in New York City. The organization boasts a multigenerational membership with representation from Pakistan, Afghanistan, India, Bangladesh, Nepal, Sri Lanka, Trinidad, Bhutan and Guyana. Programs range from helping undocumented workers in service industries organize to leadership training for young South Asians.

Chhaya CDC

Also founded in 2000, Chhaya CDC is a nonprofit that works to improve housing conditions for New York Citys South Asian community. In addition to community organizing projects and workshops aimed at housing preservation, the organization has programs that help train, educate and prepare clients for job opportunities. Chhaya CDC recently partnered with Charter Communications to open a Spectrum Learning Lab in Jackson Heights that provides access to technology and offers computer skills training.
