The U.S. Department of Health and Human Services website includes charts and links to other resources related to the agency's 2015 poverty guidelines. The site offers separate charts for Alaska and Hawaii, which have higher poverty guidelines than the 48 contiguous states and the District of Columbia.
The 2015 poverty guideline for a family of four in one of the 48 contiguous states or Washington, DC, is $24,250 in annual income. Many social programs, both government-administered and private, determine applicant eligibility based on the Health and Human Services annual poverty guidelines and applicant income. The HHS site also offers information about poverty thresholds, which the Census Bureau calculates each year, mainly for statistical use.
