of about 440,000. Demographics Nowadays, Protestants are concentrated in northern and central Germany, while Catholics are predominant in the south and west, while unaffiliated people are concentrated in the east, where they make up the majority of the population, and are significant in the north and west of the country, mainly in metropolitan areas. With the decline of Christianity in the late 20th and early 21st century, accentuated in the east by the official atheism of the former German Democratic Republic, the northeastern states of Germany are now mostly not religious (70%), with many of the people living there being agnostics and atheists. Immigrations in the late 20th and early 21st century have brought new religions into Germany, including Orthodox Christianity and Islam. Orthodox Christianity is practised among immigrated Greeks, Serbs, Russians, Romanians and other communities. Most Muslims are Sunnis and Alevis of Turkish origin, but there are a small number of Shi'a Muslims and other currents. Moreover, Germany has Europe's third-largest Jewish population (after France and the United Kingdom). Censuses Throughout history, in modern Germany several census had been carried out. Since the reformation until the 1960s the majority of the German population was Protestant (mainly Lutherans belonging to the Evangelical Church in Germany) while approximatively one third of the population was Catholic. After the German reunification, the religious landscape was significantly changed, as found by the 2011 Census, the first one since the 1960s. The latest census in 2011 found that Christianity was the religion of 53,257,550 people or 66.8% of the total population, among whom 24,869,380 or 31.2% were Catholics, 24,552,110 or 30.8% were Protestants of the Evangelical Church in Germany, 714,360 or 0.9% were members of Protestant free churches, and 1,050,740 or 1.3% were members of Eastern Orthodox and Oriental Orthodox churches. A further 2.6% was affiliated to any other Christian denomination. Jews were 83,430 people or 0.1%, and 4,137,140 or 5.2% were members of other religions. The remaining 22,223,010 people, or 27.9% of the total German population, were not believers in or not members of any religion (including atheists, agnostics and believers in unrecognised religions). Church figures and other estimates German major religious bodies publish yearly updated records of their membership. Only certain religious group publish updated figures on their official membership, and this kind of data is collected in order to levy taxes on the registered membership of those churches, which corresponds to 9%
