History

A concise historical narrative of NAICS Code 621330-03 covering global milestones and recent developments within the United States.

  • Social work as a profession has its roots in the late 19th century, with the establishment of the Charity Organization Society in London in 1869.

In the United States, the first social work program was established at Columbia University in 1898. The profession grew rapidly in the early 20th century, with the establishment of the National Association of Social Workers in 1917. Notable advancements in the industry include the establishment of the Social Security Act in 1935, which provided financial assistance to the elderly, disabled, and families with dependent children.

For example, social workers were instrumental in the establishment of the Affordable Care Act in 2010, which expanded access to healthcare for millions of Americans.
