Share of the elderly at various income-to-poverty-threshold ratios, official vs. supplemental (SPM), 2009–2011 average
Note: Elderly are age 65 and older. Under the official poverty measure, income is measured by family income for person in families and individual incomes otherwise. Under the Supplemental Poverty Measure (SPM), income consists of total SPM resources by "SPM resource unit," a slightly broader category than the family unit. See endnotes for more information.
