This method of calculating unemployment was widely used in the 1980s as well as the 1990s. This method, basically takes account of the number of heads unemployed and receiving unemployment benefits. Computation should be done with care since there may be double counting of people who have registered themselves in employment exchanges and those who are receiving the unemployment benefits.
The method has two advantages of calculating unemployment by using administrative records. Firstly, this method takes a complete count of the unemployed and so it is free from any sampling error.
Secondly, Obtaining such data is also very cost effective and is available on a regular basis.
However, this method of computation is fraught with certain limitations. The collection of data follows administrative rules and regulations, which may not be in line with statistical principles. Again, since different countries follow different computational rules, it is difficult to compare the unemployment statistics across different countries. Another difficulty is that the rules tend to change over time and so the unemployment data cannot be compared across different time horizons.
