A low-income household is one whose income is low relative to other households of the same size in their area/region. In the United States, a household is commonly classified as low-income and may be eligible for certain types of government assistance, including Federal Pell Grant, if its income is less than two times the poverty threshold, as determined by the U.S. Department of Health and Human Services. In 2021, a family of four living in the 48 contiguous states or Washington, D.C. would be considered low income if their household income was less than $53,000.
