According to a Vanguard report, the recently published report by Steve Hanke, an economist from John Hopkins University in Baltimore, United state, listed Nigeria, Venezuela, Iran, Brazil, others among the first ten (10) miserable countries in the world. 
According to the report Venezuela was listed as the most miserable country in the world. Reacting to this Hanke said, “Venezuela holds the inglorious title of the most miserable country in the world in 2018, as it did in 2017, 2016, and 2015.”
However, Argentina jumped to the No. 2 spot after yet another peso crisis. Since its founding, Argentina has been burdened with numerous economic crises. Most can be laid at the feet of domestic mismanagement and currency problems (read: currency collapses). Iran took third in the ranking, before Brazil that made it to the fourth position.
Turkey took the fifth position as the giant of Africa Nigeria emerged sixth. The Misery Index was calculated using economic indices including unemployment, inflation and bank lending rates. For Nigeria, unemployment rate was the major contributing factor to its miserable state.
According to Hanke, “The first Misery Index was constructed by economist Art Okun in the 1960s as a way to provide President Lyndon Johnson with an easily digestible snapshot of the economy. That original Misery Index was just a simple sum of a nation’s annual inflation rate and its unemployment rate. The Index has been modified several times, first by Robert Barro of Harvard and then by myself.
“My modified Misery Index is the sum of the unemployment, inflation and bank lending rates, minus the percentage change in real GDP per capita. Higher readings on the first three elements are “bad” and make people more miserable. These are offset by a “good” (GDP per capita growth), which is subtracted from the sum of the “bads.”
A higher Misery Index score reflects a higher level of “misery,” and it’s a simple enough metric that a busy president, without time for extensive economic briefings, can understand at a glance.
