LONDON, Aug 9 (APP)- By 2050 Muslims could be 20 per cent of the European population due to rising level of immigration and low birth rates among Europe’s indigenous population.Britain, Spain and Holland will have an even higher proportion of Muslims in a shorter amount of time, says a report in “Daily Telegraph”.    Last year, five per cent of the total population of the 27 EU countries was Muslim but  this will now increase significantly over the next four decades as more and more Muslims migrate to Europe for better life while the population of indigenous Europeans declines.Data gathered by the newspaper from various sources indicate that Britain, Spain and Holland will have an even higher proportion of Muslims in a shorter amount of time.The UK, which currently has 20 million fewer people than Germany, is also projected to be the EU’s most populous country by 2060, with 77 million people.The findings have led to allegations that policy-makers are failing to confront the widespread challenges of the “demographic time bomb”.Experts say that there has been a lack of debate on how the population changes will affect areas of life from education and housing to foreign policy and pensions.Although some polls have pointed to a lack of radicalisation in the Muslim community, little attention is being given to the integration of migrants, it is claimed, with fears of social unrest in years to come.
