The study of the economics of global manufacturing, for example, is of constant debate in the financial and political spheres. The Bureau of Labor Statistics (BLS) releases employment data in a report called the non-farm payrolls, on the first Friday of each month. Generally, sharp increases in employment indicate prosperous economic growth.

By correlating the data points with information relating to the selected economic variable, you can observe patterns in situations exhibiting dependency between the data points and the chosen variable.

Because consumer spending represents more than two-thirds of GDP, this report is very useful to gauge the economy's general direction. Greater-than-expected price increases are considered a sign of inflation, which will likely cause the underlying currency to depreciate. Users have the ability to make their own custom charts, XY plots, regressions, and get data in excel files, or in copy & paste format for dumping to other computer programs Dowling E.T, Introduction to Mathematical Economics, 2nd Edition, Schaum’s Series, McGraw-Hill, New York, 2003(E TD) 3. Time series analysis can be useful to see how a given asset, security, or economic variable changes over time. Also, because the report's data is based on the previous month sales, it is a timely indicator.
