what is the standard and poor's 500 index
S&P 500 Index The Standard & Poor'sÂ 500, often abbreviated as the S&P 500, or just "the S&P",[6][7] is an American stock market index based on the market capitalizations of 500 large companies having common stock listed on the NYSE or NASDAQ. The S&P 500 index components and their weightings are determined by S&P Dow Jones Indices. It differs from other U.S. stock market indices, such as the Dow Jones Industrial Average or the Nasdaq Composite index, because of its diverse constituency and weighting methodology. It is one of the most commonly followed equity indices, and many consider it one of the best representations of the U.S. stock market, and a bellwether for the U.S. economy.[8] The National Bureau of Economic Research has classified common stocks as a leading indicator of business cycles.[9]
Poverty in the United Kingdom The most common measure for poverty, as used in the Child Poverty Act 2010, is ‘household income below 60 percent of median income’. The median is such an income that exactly a half of households earn more than that and the other half earns less.[79]
