Final answer:
You seem to be mixing Transparency International's 2013 Index with the Heritage Foundation's Index of Economic Freedom. The 2016 Heritage Foundation report lists countries based on economic freedom but does not rank several countries due to extreme instability. Hong Kong is noted for its autonomy in these measures.
Step-by-step explanation:
Transparency International's 2013 Index, which you inquired about, specifically evaluates the perceived levels of public sector corruption. However, the data you've mentioned, such as the classification of countries as not free and the emanation of countries with extreme instability from the economic freedom rankings, is not from Transparency International but rather from the Heritage Foundation's Index of Economic Freedom reports from different years. The 2016 Heritage Foundation's Index of Economic Freedom report indeed ranks countries based on economic freedoms, making a distinction between the most free and the least free countries. It specifically notes that because of extreme instability, several countries could not be ranked, which include Afghanistan, Iraq, Libya, Syria, Somalia, and Yemen. Additionally, it acknowledges that Hong Kong, despite not being an independent country, enjoys a degree of autonomy that warrants treating it as a separate entity for economic measurements.
