Which department is primarily responsible for the delivery of social services at the county level?

The Department of Social Services is primarily responsible for the delivery of social services at the county level. This department oversees various programs and services designed to support individuals and families in need, such as assistance with housing, food security, childcare, financial assistance, and mental health services. Its focus is on addressing the social welfare needs of the community and ensuring that vulnerable populations have access to the resources they require.

Other departments listed, such as the Department of Health and Human Services, while also involved in the welfare of communities, typically have a broader health-related focus and may not specifically handle the array of social services that the Department of Social Services does. The Department of Labor primarily deals with employment-related issues, and the Department of Education focuses on educational services and opportunities. Therefore, the central role of the Department of Social Services in managing social services at the county level makes it the correct answer.
