To understand present day demographics in Europe (and France in particular) you must look at both age distribution, and the age when births occur. Simply looking at population percentages alone will not get you anywhere close.
The Muslim population of France is much, much younger than the ethnic French, and the age at which Muslim women have children is much younger. Hence there are many more Muslim women giving birth than their percent of the population would indicate.
The result is not just that a disproportionate number of all young people in France are Muslim, but that 50% of all births in France are to Muslim parents. Although this is a relatively new phenomenon, one early result is that 25% of the enlisted troops in the French armed forces are now Muslim.
Source? The French government has refused to allow collection of census data based on religion. Hence there are no "official" sources (can you say, "DENIAL"?).
The Catholic Church has stepped into the gap, and their numbers are considered the most reliable in France. Based on the Catholic Church's estimates (including the Catholic estimate of the current Muslim population), a birth rate of 1.3/woman among the ethnic French is all that is needed for 50% of all births in France to be Muslim. This is well within the present day norm for "old" Europe.

Although French Muslims of African or Turkish origin are typically younger than the rest of the French population, fertility rates among immigrant women tend to conform with the French norm after their arrival. The gap in fertility rates between immigrant women and French women is 0.46. While Europe on the whole is experiencing declining birth rates, there are two demographic exceptions: France and Ireland. In France, the fertility rate is 1.94 children born per woman (2005.) (In comparison, the U.S. fertility rate is 2.08 children born per woman.) Without immigrant women, this figure would drop by 0.05 children born per woman. In other words, one can hardly speak of a "demographic time bomb," "colonization in reverse," or the "Islamicization of France."
Again you have no clue about French demographics and you all your numbers are false...
There are no official numbers on muslims in France, because collecting such data is against the law. The best statisticians have found that the number 5 millions is exagerated... Moreover looking at the names of babies, ity isn't true that so many French birth are to muslims...
