According to [url=https://en.wikipedia.org/wiki/Statistics_Netherlands]Statistics Netherlands[/url] (CBS), a Dutch governmental institution, about 5% of the total Dutch population are Muslims (24 October 2007). Earlier statistics presented by the CBS showed a larger number of Muslims, but this information was solely based on ethnicity and not on religious belief.[url=https://en.wikipedia.org/wiki/Islam_in_the_Netherlands#cite_note-CBS-10][10][/url] Since 2007 a reduction of around 50.000 Muslims was measured by the CBS, but this is not seen as a significant drop; it is seen as a result of improved research parameters. Secularisation of the second generation has nonetheless been observed, mostly amongst citizens of Iranian and Turkish background.

Like most non-Western immigrants, most Muslims live in the four major cities of the country, [url=https://en.wikipedia.org/wiki/Amsterdam]Amsterdam[/url],[url=https://en.wikipedia.org/wiki/Rotterdam]Rotterdam[/url], [url=https://en.wikipedia.org/wiki/The_Hague]The Hague[/url] and [url=https://en.wikipedia.org/wiki/Utrecht_(city)]Utrecht[/url]. An estimated 140,000 Muslims reside in the capital where they form around 17 per cent of the population. Half of these Muslims are predominantly Arabic and Berber-speaking communities from the Maghreb region, Egypt and the Middle East. Turks make up 25 per cent of the Muslim population in Amsterdam. There are also relatively many Turks in [url=https://en.wikipedia.org/wiki/Enschede]Enschede[/url], [url=https://en.wikipedia.org/wiki/Arnhem]Arnhem[/url] and[url=https://en.wikipedia.org/wiki/Zaanstad]Zaanstad[/url].[url=https://en.wikipedia.org/wiki/Islam_in_the_Netherlands#cite_note-11][11][/url]

There were 850,000 Dutch residents who professed Islam in 2006. Of this 38% were ethnic Turkish, 31% were Moroccan, 26% were other Asian/African, 4% were European (Non-Dutch) and 1% (12,000 people) were native Dutch. 40,000 of the Muslims were [url=https://en.wikipedia.org/wiki/Pakistanis_in_the_Netherlands]Pakistanis[/url], 34,000 were Surinamese, 31,000 were Afghan and 27,000 were Iraqi.[url=https://en.wikipedia.org/wiki/Islam_in_the_Netherlands#cite_note-12][12][/url] At the end of 2012 the number of Muslims is estimated to be around 4% of the total Dutch population according to the Dutch Central Bureau of Statistics.

NOW, explain to me how in 15 years 4% can grow to 50% with 1/4 of babies being born in islam
