This statistic shows the estimated number of Muslims living in different European countries as of 2016. Approximately 5.72 million Muslims were estimated to live in France, the most of any country listed. Germany and the United Kingdom also have large muslim populations with 4.95 million and 4.13 million respectively.

This statistic displays the projected Muslim population proportions in selected European countries in 2050, by scenario. In 2010 the proportion of Muslims in the population of Germany was 4.1 percent, compared with 6.3 percent in the UK and 7.5 percent in France. Depending on the different migration scenarios estimated here, Germany's share of Muslims in the population could rise up to 19.7 percent of it's population by 2050, higher than both the UK and France, with projected Muslim populations of 17.2 and 18 percent respectively.

This statistic shows the number of sukuk bonds listed and traded on the London Stock Exchange (United Kingdom) between 2009 and 2016. Sukuk are Islamic bonds, which are structured in a specific way, allowing to generate financial returns. It ensures no infringement of the Islamic law, which prohibits benefitting from the interest rate. The interest rate is called "riba" in Islamic finance, which is understood as "making money on money" and is seen as unjust. In 2016, London was the leading center for Islamic finance in Western Europe, after Saudi Arabia, Malaysia, United Arab Emirates, Kuwait, Quatar, Turkey, Indonesia, Bahrain and Pakistan. Between 2009 and 2016, a steady growth in nuber of sukuk bonds offered on the London Stock Exchange could be observed. The numbers rose from 18 bonds traded in 2009, up to 57 sukuk listings on the London Stock Exchange as of 2016. Not only the number of traded bonds has grown over time, also the value of sukuk traded on LSE has increased in the recent years.

In 1800, the population of the area of modern-day Bangladesh was estimated to be just over 19 million, a figure which would rise steadily throughout the 19th century, reaching over 26 million by 1900. At the time, Bangladesh was the eastern part of the Bengal region in the British Raj, and had the most-concentrated Muslim population in the subcontinent's east. At the turn of the 20th century, the British colonial administration believed that east Bengal was economically lagging behind the west, and Bengal was partitioned in 1905 as a means of improving the region's development. East Bengal then became the only Muslim-majority state in the eastern Raj, which led to socioeconomic tensions between the Hindu upper classes and the general population. Bengal Famine During the Second World War, over 2.5 million men from across the British Raj enlisted in the British Army and their involvement was fundamental to the war effort. The war, however, had devastating consequences for the Bengal region, as the famine of 1943-1944 resulted in the deaths of up to three million people (with over two thirds thought to have been in the east) due to starvation and malnutrition-related disease. As the population boomed in the 1930s, East Bengal's mismanaged and underdeveloped agricultural sector could not sustain this growth; by 1942, food shortages spread across the region, millions began migrating in search of food and work, and colonial mismanagement exacerbated this further. On the brink of famine in early-1943, authorities in India called for aid and permission to redirect their own resources from the war effort to combat the famine, however these were mostly rejected by authorities in London. While the exact extent of each of these factors on causing the famine remains a topic of debate, the general consensus is that the British War Cabinet's refusal to send food or aid was the most decisive. Food shortages did not dissipate until late 1943, however famine deaths persisted for another year. Partition to independence Following the war, the movement for Indian independence reached its final stages as the process of British decolonization began. Unrest between the Raj's Muslim and Hindu populations led to the creation of two separate states in1947; the Muslim-majority regions became East Pakistan (now Bangladesh) and West Pakistan (now Pakistan), separated by the Hindu-majority India. Although East Pakistan's population was larger, power lay with the military in the west, and authorities grew increasingly suppressive and neglectful of the eastern province in the following years. This reached a tipping point when authorities failed to respond adequately to the Bhola cyclone in 1970, which claimed over half a million lives in the Bengal region, and again when they failed to respect the results of the 1970 election, in which the Bengal party Awami League won the majority of seats. Bangladeshi independence was claimed the following March, leading to a brutal war between East and West Pakistan that claimed between 1.5 and three million deaths in just nine months. The war also saw over half of the country displaced, widespread atrocities, and the systematic rape of hundreds of thousands of women. As the war spilled over into India, their forces joined on the side of Bangladesh, and Pakistan was defeated two weeks later. An additional famine in 1974 claimed the lives of several hundred thousand people, meaning that the early 1970s was one of the most devastating periods in the country's history. Independent Bangladesh In the first decades of independence, Bangladesh's political hierarchy was particularly unstable and two of its presidents were assassinated in military coups. Since transitioning to parliamentary democracy in the 1990s, things have become comparatively stable, although political turmoil, violence, and corruption are persistent challenges. As Bangladesh continues to modernize and industrialize, living standards have increased and individual wealth has risen. Service industries have emerged to facilitate the demands of Bangladesh's developing economy, while manufacturing industries, particularly textiles, remain strong. Declining fertility rates have seen natural population growth fall in recent years, although the influx of Myanmar's Rohingya population due to the displacement crisis has seen upwards of one million refugees arrive in the country since 2017. In 2020, it is estimated that Bangladesh has a population of approximately 165 million people.

Since 1970, the worst terrorist attack in the United Kingdom was the downing of Pan Am Flight 103 in December 1988 above Lockerbie, Scotland, which caused 270 fatalities. Of the ten attacks worst terrorist attacks in the UK, seven were related to the troubles in Northern Ireland, while two were related to Islamic extremism. The London 7/7 bombings in 2005, which caused the deaths of 56 people, and the Manchester Arena bombing in May 2017, which claimed the lives of 23 people. Are terrorist attacks in the UK on the rise? When compared with earlier decades, the number of terrorist attacks in the UK has declined considerably. Throughout the 1970s, there were approximately 1,644 terrorist attacks, 1,315 in the 1980s, and 1,214 in the 1990s, compared with just 325 in the 2000s, and 925 in the 2010s. During this period, the year with the highest number of attacks was 1972, when there were 292. Although the period between 2013 and 2018 saw a high volume of terrorist attacks, this has started to decline in more recent years. In 2021, for example there were 40 terrorist attacks, the fewest since 2009. A global threat In 2022, 21,943 people lost their lives due to terrorism, with the Democratic Republic of Congo suffering the highest number of attacks at 984. The UK was not alone in seeing the intensity of terror attacks increase in the mid-2010s either. The Paris Attacks of November 2015 caused 130 fatalities, while the Nice attacks in 2016 led to 86 deaths, some of the worst terrorist incidents to have ever taken place in Europe. Due to these attacks, the number of deaths caused by terrorism was significantly higher in 2015 and 2016 than in other years, at 152, and 142 respectively.
