Final answer:
The federal poverty line represents the minimal income level the government considers necessary for basic life needs, based on three times a low-cost food budget. For 2023, a family of four earning below $30,000 is under the poverty line. This measure has limitations and doesn't include non-cash benefits like Medicaid or housing assistance.
Step-by-step explanation:
The minimal level of income that the federal government considers necessary for basic subsistence is known as the federal poverty line (FPL). It is calculated to include incomes that are less than three times a low-cost food budget. In 2023, for example, a family of four earning below $30,000 would be considered to be living in poverty. This calculation is based on historical data reflecting that food expenditure used to be a third of a family's budget in the 1950s. While it attempts to set a standard for poverty, it does not factor in non-cash government aid such as Medicaid or federal housing assistance.
Certain questions arise regarding the appropriateness of a national poverty line in a country with varying costs of living and income levels across different states. The poverty line is also influenced by changes in cost of living over time, which can lead to adjustments such as the increases to the federal minimum wage.
