Albania is a parliamentary republic, with a population of just under three million, according to 2011 census. The country’s current Constitution was adopted in 1998. Albania was admitted to NATO in 2009 and is currently a potential candidate country to European Union. The country has experienced significant economic transformation over the past two decades, from a centrally planned to a free market economy. However, the disparity between the capital, Tirana, and other nearby, developed cities, compared to more remote areas is serious.
