Sierra Leone, officially the Republic of Sierra Leone, is a country in West Africa. It is bordered by Guinea in the north-east, Liberia in the south-east, and the Atlantic ocean in the south-west. Sierra Leone has a tropical climate, with a diverse environment ranging from savannah to rainforests. Sierra Leone has a total area of 71,740 km2 (27,699 sq mi) and an estimated population of 6 million (2011 United Nations estimate). Freetown is the capital, largest city, and its economic and political centre. Bo is the second largest city and second major economic center in the country. The country is divided into four geographical regions: the Northern Province, Eastern Province, Southern Province and the Western Area, which are further divided into fourteen districts. About sixteen ethnic groups inhabit Sierra Leone, each with their own language and custom. The two largest and most influential are the Temne and the Mende people. The Temne are predominantly found in the north of the country, while the Mende are predominant in the south-east. Although English is the official language spoken at schools and government administration, the Krio language is the most widely spoken language in the country and unites all the different ethnic groups in the country, especially in their trade and social interaction with each other. Sierra Leone is a predominantly Muslim country, though with an influential Christian minority. Sierra Leone is regarded as one of the most religiously tolerant nations in the world. Muslims and Christians collaborate and interact with each other peacefully. Religious violence is very rare in the country. Sierra Leone has relied on mining, especially diamonds, for its economic base. It is also among the largest producers of titanium and bauxite, a major producer of gold, and has one of the world's largest deposits of rutile. Sierra Leone is home to the third-largest natural harbour in the world. Despite exploitation of this natural wealth, 70% of its people live in poverty. Sierra Leone became independent in 1961. Government corruption and mismanagement of the country's natural resources contributed to the Sierra Leone Civil War (1991 to 2002), which over more than a decade devastated the country. It left more than 50,000 people dead, much of the country's infrastructure destroyed, and over two million people displaced as refugees in neighbouring countries. More recently, the 2014 Ebola outbreak threatens to lead the country into a humanitarian crisis situation and a negative spiral of weaker economic growth. The country has an extremely low life expectancy.

1.  Relying on agencies from each country, as well as a synthesis of data from United Nations divisions, Eurostate Demographic statistics, the U.S. Census international database, and its own data collection, the World Bank’s Open Data site offers free and open access to data about development in countries around the globe.

2.  The U.S. State Department's International Religious Freedom Report is submitted to Congress annually by the Department of State in compliance with Section 102(b) of the International Religious Freedom Act (IRFA) of 1998. This report supplements the most recent Human Rights Reports by providing additional detailed information with respect to matters involving international religious freedom. It includes individual country chapters on the status of religious freedom worldwide. A dataset with these and the other international measures highlighted on the country pages can be downloaded from this website. These State Department reports are open source.

3.  The article by Brian Grim and Roger Finke describes the coding of the U.S. State Department’s International Religious Freedom reports. The 2003, 2005, and 2008 reports were coded by researchers at the Association of Religion Data Archives. The GRI, GFI and SRI values reported on the National Profiles are averages from the 2003, 2005, and 2008 International Religious Freedom reports, while the Religious Persecution measure is an average from the 2005 and 2008 reports. All other measures derived from the International Religious Freedom reports were coded from the reports 2008. A data file with all of the 2008 coding, as well as data files with other cross national collections are available for preview and download from the data archive on this site. Used with permission.
