Protestantism by country

There are between 800 and more than 900 million Protestants worldwide, among approximately 2.4 billion Christians. In 2010, a total of more than 800 million included 300 million in Sub-Saharan Africa, 260 million in the Americas, 140 million in Asia-Pacific region, 100 million in Europe and 2 million in Middle East-North Africa. Protestants account for nearly forty percent of Christians worldwide and more than one tenth of the total human population. Various estimates put the percentage of Protestants in relation to the total number of world's Christians at 33%, 36%, 36.7%, and 40%, while in relation to the world's population at 11.6% and 13%.

In European countries which were most profoundly influenced by the Reformation, Protestantism still remains the most practiced religion. These include the Nordic countries and the United Kingdom. In other historical Protestant strongholds such as Germany, the Netherlands, Switzerland, Latvia, Estonia and Hungary, it remains one of the most popular religions. Although Czech Republic was the site of one of the most significant pre-reformation movements, there are only few Protestant adherents; mainly due to historical reasons like persecution of Protestants by the Catholic Habsburgs, restrictions during the Communist rule, and also the ongoing secularization. Over the last several decades, religious practice has been declining as secularization has increased. According to a 2012 study about Religiosity in the European Union in 2012 by Eurobarometer, Protestants made up 12% of the EU population. According to Pew Research Center, Protestants constituted nearly one fifth (or 17.8%) of the continent's Christian population in 2010. Clarke and Beyer estimate that Protestants constituted 15% of all Europeans in 2009, while Noll claims that less than 12% of them lived in Europe in 2010.
