Here you can see an Excel file with impact factors for Social Science journals.

The journal impact factor is a measure of the frequency with which the "average article" in a journal has been cited in a particular year. The impact factor is commonly used as a cue to a journal's relative importance, especially when compared to others in the same field. The impact factor is calculated by dividing the number of current citations to articles published in the two previous years by the total number of articles published in the two previous years.

The first two spreadsheets deal just with Psychology journals on the Social Science Citation Index (SSCI) but I have managed to get hold of similar data for a broader range of Social Science journals (see the 3rd spreadsheet). Entirely arbitrarily, just for the Psychology journals on the graph and spreadsheet, I put journals with an impact factor greater than 1 in bold type (about 42% of Psychology journals have an impact of 1 or more; the 50% point is at 0.853). Those whose impact is in the top 25% are coloured blue, unless they are also in the top 10% in which case they are coloured in red. The distribution of impact factors is heavily skewed - fewer than 13% of Psychology journals listed on the SSCI have an impact greater than 2.0.
