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.

The UK halal tourism industry is expected to witness huge growth between 2025 and 2035, with rising demand for travel options that comply with the Islamic law of halal, the growing Muslim population, and growing awareness of services in halal travel. With a value of USD 5.4 billion in 2025, the market is expected to reach USD 10.4 billion by 2035, recording a CAGR of 6.7% over the next decade. This growth can be attributed to several factors, including a rise in both domestic and international travelers seeking halal-friendly experiences, significant advancements in tourism services designed specifically for Muslim travelers, and the increasing availability of halal-friendly destinations across the UK.

In 1800, the population of the region of present-day India was approximately 169 million. The population would grow gradually throughout the 19th century, rising to over 240 million by 1900. Population growth would begin to increase in the 1920s, as a result of falling mortality rates, due to improvements in health, sanitation and infrastructure. However, the population of India would see it’s largest rate of growth in the years following the country’s independence from the British Empire in 1948, where the population would rise from 358 million to over one billion by the turn of the century, making India the second country to pass the billion person milestone. While the rate of growth has slowed somewhat as India begins a demographics shift, the country’s population has continued to grow dramatically throughout the 21st century, and in 2020, India is estimated to have a population of just under 1.4 billion, well over a billion more people than one century previously. Today, approximately 18% of the Earth’s population lives in India, and it is estimated that India will overtake China to become the most populous country in the world within the next five years.
