United States -- Muslim 1.0%
Australia -- Muslim 1.5%
Canada -- Muslim 1.9%
China -- Muslim 1%-2%
Italy -- Muslim 1.5%
Norway -- Muslim 1.8%
At 2% and 3% they begin to proselytize from other ethnic minorities and disaffected groups with major recruiting from the jails and among street gangs:
Denmark -- Muslim 2%
Germany -- Muslim 3.7%
United Kingdom -- Muslim 2.7%
Spain -- Muslim 4%
Thailand -- Muslim 4.6%

From 5% on they exercise an inordinate influence in proportion to their percentage of the population.
They will push for the introduction of halal (clean by Islamic standards) food, thereby securing food preparation jobs for Muslims. They will increase pressure on supermarket chains to feature it on their shelves -- along with threats for failure to comply. At this point, they will work to get the ruling government to allow them to rule themselves under Sharia, the Islamic Law.

France -- Muslim 8%
Philippines -- Muslim 5%
Sweden -- Muslim 5%
Switzerland -- Muslim 4.3%
The Netherlands -- Muslim 5.5%
Trinidad & Tobago -- Muslim 5.8%

When Muslims reach 10% of the population, they will increase lawlessness as a means of complaint about their conditions ( Paris -- car-burnings). Any non-Muslim action that offends Islam will result in uprisings and threats

( Amsterdam -- Mohammed cartoons).
Guyana -- Muslim 10%
India -- Muslim 13.4%
Israel -- Muslim 16%
Kenya -- Muslim 10%
Russia -- Muslim 10-15%

After reaching 20% expect hair-trigger rioting, jihad militia formations, sporadic killings and church and synagogue burning:
Ethiopia -- Muslim 32.8%

At 40% you will find widespread massacres, chronic terror attacks and ongoing militia warfare:
Bosnia -- Muslim 40%
Chad -- Muslim 53.1%
Lebanon -- Muslim 59.7%

From 60% you may expect unfettered persecution of non-believers and other religions, sporadic ethnic cleansing (genocide), use of Sharia Law as a weapon and Jizya, the tax placed on infidels:

Albania -- Muslim 70%
Malaysia -- Muslim 60.4%
Qatar -- Muslim 77.5%
Sudan -- Muslim 70%

After 80% expect State run ethnic cleansing and genocide:
Bangladesh -- Muslim 83%
Egypt -- Muslim 90%
Gaza -- Muslim 98.7%
Indonesia -- Muslim 86.1%
Iran -- Muslim 98%
Iraq -- Muslim 97%
Jordan -- Muslim 92%
Morocco -- Muslim 98.7%
Pakistan -- Muslim 97%
Palestine -- Muslim 99%
Syria -- Muslim 90%
Tajikistan -- Muslim 90%
Turkey -- Muslim 99.8%
United Arab Emirates -- Muslim 96%

100% will usher in the peace of "Dar-es-Salaam"-- the Islamic House of Peace -- there's supposed to be peace because everybody is a Muslim:
Afghanistan -- Muslim 100%
Saudi Arabia -- Muslim 100%
Somalia -- Muslim 100%
Yemen -- Muslim 99.9%
Of course, that's not the case. To satisfy their blood lust, Muslims then start killing each other for a variety of reasons.
"Before I was nine I had learned the basic canon of Arab life. It was me against my brother; me and my brother against our father; my family against my cousins and the clan; the clan against the tribe; and the tribe against the world and all of us against the infidel." -- Leon Uris, "The Haj"
It is good to remember that in many, many countries, such as France , the Muslim populations are centered around ghettos based on their ethnicity. Muslims do not integrate into the community at large. Therefore, they exercise more power than their national average would indicate.
