There are between 800 million and 1 billion Protestants worldwide, among approximately 2.5 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 the 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 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 2019 study about religiosity in the European Union (EU) by Eurobarometer, Protestants made up 9% 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. Changes in worldwide Protestantism over the last century have been significant. Since 1900, Protestantism has spread rapidly in Africa, Asia, Oceania and South America. That caused Protestantism to be called a primarily non-Western religion. Much of the growth has occurred after World War II, when decolonization of Africa and abolition of various restrictions against Protestants in Latin American countries occurred. According to one source, Protestants constituted respectively 2.5% of South Americans, 2% of Africans, and 0.5% of Asians in 1900. In 2000, these percentages had increased to 17%, more than 27%, and 5.5%, respectively. According to Mark A. Noll, 79% of Anglicans lived in the United Kingdom in 1910, while most of the remainder were found in the United States and across
