Is the statistics of Islam population in Europe accurate because wherever i go i see only Muslim around?
Islam is growing fast in Europe (much much faster than in the US). Some people convert, yes, but the increase is more about immigration and high birth rates. Yet, statistics might be misleading. Many immigrants are not citizen, some are even illegal. You will more likely see Indian and Pakistani Muslims in Britain; Turks in Germany, Belgium, Switzerland, the Netherlands and Austria; Algerians in France; Albanians in Italy, etc. In the British and French cases, the immigration is flowing from former colonies.
