New Freedom House Data -- 2007 was not a good year...

Here is a description of the 2007 Freedom House data rating the level of democracy in countries around the world. Apparently, 2007 was not a very good year for the advancement of democracy.

Perhaps things will change with Castro stepping down?

Here is a summary quote from the report:

The year 2007 was marked by a notable setback for global freedom. The decline, which was reflected in reversals in one-fifth of the world’s countries, was most pronounced in South Asia, but also reached significant levels in the former Soviet Union, the Middle East and North Africa, and sub-Saharan Africa. It affected a substantial number of large and politically important countries—including Russia, Pakistan, Kenya, Egypt, Nigeria, and Venezuela—whose declines have wider regional and global implications. Other countries experienced reversals after a period of progress toward democracy, including pivotal states in the Arab Middle East. While many more countries suffered declines than registered improvements, the degree of change reflected in some countries was modest while in others the decline was more substantial. …[The] results for 2007 marked the second consecutive year in which the survey registered a decline in freedom, representing the first two-year setback in the past 15 years. In all, nearly four times as many countries showed significant declines during the year as registered improvements.
