Poverty
The poverty line threshold of $1.90 per day, as set by the World Bank, is controversial. Each nation has its own threshold for absolute poverty line; in the United States, for example, the absolute poverty line was US$15.15 per day in 2010 (US$22,000 per year for a family of four), while in India it was US$1.0 per day and in China the absolute poverty line was US$0.55 per day, each on PPP basis in 2010. These different poverty lines make data comparison between each nation's official reports qualitatively difficult. Some scholars argue that the World Bank method sets the bar too high, others argue it is low. Still others suggest that poverty line misleads as it measures everyone below the poverty line the same, when in reality someone living on $1.20 per day is in a different state of poverty than someone living on $0.20 per day. In other words, the depth and intensity of poverty varies across the world and in any regional populations, and $1.25 per day poverty line and head counts are inadequate measures.
Medicaid coverage gap
In the United States, the Medicaid coverage gap refers to the group of uninsured people (in states that have opted out of the Medicaid expansion under the Affordable Care Act (ACA) who are both ineligible for Medicaid under its previous rules, which still apply in these states, and too poor to qualify for the ACA's subsidies and credits that were designed to allow middle-class Americans to purchase health insurance. The number of Americans in this gap has been estimated to be almost 3 million as of January 2016, according to the Kaiser Family Foundation. The Foundation has also said that 90% of the people in this gap live in the South. In states that have not expanded Medicaid, eligibility requirements for Medicaid are limited to parents making 44% or less of the poverty line, and in almost all such states, all adults without children are ineligible. The coverage gap results from this and a number of factors, such as the fact that the ACA was designed so that the poor would received coverage through Medicaid and so did not include an alternative program for them. For example, as of April 2014, someone living in Texas, a nonexpansion state, had to be making less than $3,737 per year to be eligible for Medicaid, and had to make at least $11,490 (if a single person) or $23,550 (for a family of four) to be eligible for ACA subsidies. On November 1, 2015, an episode of Last Week Tonight with John Oliver dedicated its main segment to discussing the Medicaid coverage gap.
