  As of 2020, about 24% of the global population, or about 1.9 billion people, are Muslims. In 1900, this estimate was 12.3%, in 1990 it was 19.9% and projections suggest the proportion will be 29.7% by 2050. The Pew Research Center estimates that 87–90% of Muslims are Sunni and 10–13% are Shia. Approximately 49 countries are Muslim-majority, with 62% of the world's Muslims living in Asia, and 683 million adherents in Indonesia, Pakistan, India, and Bangladesh alone. Arab Muslims form the largest ethnic group among Muslims in the world, followed by Bengalis and Punjabis. Most estimates indicate China has approximately 20 to 30 million Muslims (1.5% to 2% of the population). Islam in Europe is the second-largest religion after Christianity in many countries, with growth rates due primarily to immigration and higher birth rates of Muslims in 2005, accounting for 4.9% of all of Europe's population in 2016.
  
  Religious conversion has no net impact on the Muslim population growth as "the number of people who become Muslims through conversion seems to be roughly equal to the number of Muslims who leave the faith." Although, Islam is expected to experience a modest gain of 3 million through religious conversion between 2010 and 2050, mostly from Sub Saharan Africa (2.9 million).
  
  According to a report by CNN, "Islam has drawn converts from all walks of life, most notably African-Americans". In Britain, around 6,000 people convert to Islam per year and, according to an article in the British Muslims Monthly Survey, the majority of new Muslim converts in Britain were women. According to The Huffington Post, "observers estimate that as many as 20,000 Americans convert to Islam annually", most of them being women and African-Americans.
  
  By both percentage and total numbers, Islam is the world's fastest growing major religious group, and is projected to be the world's largest by the end of the 21st century, surpassing that of Christianity. It is estimated that, by 2050, the number of Muslims will nearly equal the number of Christians around the world, "due to the young age and high fertility rate of Muslims relative to other religious groups."
