Since Macroeconomic studies the performance of the economy as a whole, The unemployment rate, inflation and consumer price index are part of Macroeconomics studies because they are economic indexes which are aggregated indicators of the whole economy. ‘The unemployment rate in the United States was 5.1 percent in September 2015’ applies to macroeconomics because its referring to the performance of the labour market across all the industries in a national level. ‘ U.S. output, adjusted for inflation, increased by 2.4 percent in 2014’ also applies to macroeconomics because is measures the production of goods and services from every national industry. Finally, ‘consumer price index rose by 0.2 percent from August 2014 to August 2015’ also applies to macroeconomics since it measures the change in prices of all the goods and services in the economy.
