Which program provides cash assistance to low-income families with children?

The program that provides cash assistance to low-income families with children is TANF, which stands for Temporary Assistance for Needy Families. This program is specifically designed to aid families by providing financial support to help them meet basic needs, such as housing, food, and childcare. TANF also aims to encourage self-sufficiency and work by offering job training and employment services.

Other programs mentioned, although also designed to assist individuals and families in need, do not focus on cash assistance for low-income families with children. Medicare is primarily a health insurance program for individuals aged 65 and older or those with specific disabilities. The Healthy Indiana Plan is a health coverage program for low-income adults without dependent children, and the Healthy Start Program generally focuses on maternal and child health services, rather than cash assistance. Thus, TANF is the most relevant program for this specific purpose.
