Macroeconomics is majorly concerned with the unemployment rates, rates of inflation and the total value of all the finished goods and services produced within a particular state over a certain period of time.

Unemployment refers to the number of individuals who are capable of providing labour but they are not able to find employment. Higher rates of unemployment indicates a shrinking economy while lower rates of unemployment indicate that the economy is growing and thus more labour is utilized to maintain the higher levels of production.

Inflation refers to a situation in which costs of goods and services generally rise.

Macroeconomic series data are normally collected in monthly periods .These data should not be collected more than once per month. This is because it is impractical and inconveniencing, for example collecting the data on unemployed people on daily basis is really inconveniencing. The process is also expensive, cumbersome and time wasting.
