The HHI is calculated by squaring the market share of each firm competing in the market and then summing the resulting numbers. The Herfindahl-Hirschman Index (HHI) is a measure of the degree of concentration in an industry. To calculate the HHI, take the market shares of the four largest firms in an industry, square each of these numbers and then sum them. For example, imagine an industry in which the four largest firms have the following market shares: 5%, 10%, 15%, 20%.

I am trying to calculate the Herfindahl-Hirschman Index using the graphical user interface in SPSS 22. As part of this, I would like to calculate the Herfindahl-Hirschman Index for the following scenario. To understand what I am talking about, I have attached a table. The first column depicts different IDs, e.g. the first five rows have the same ID. The second column depicts different regions for the corresponding ID. Although the Herfindahl-Hirschman Index is one of the most commonly used measures of diversity, there are other measures in use, including the raw number of different religions of a certain share or size in a country. 15.
