Expect daily intimidation and violent jihad

As long as the Muslim population remains around or under 2% in any given country, they will be for the most part be mistakenly regarded as a peace-loving minority, and not as a threat to other citizens.
This is the case in:

United States -- Muslim 0..6%
Australia -- Muslim 1.5%
Canada -- Muslim 1.9%
China -- Muslim 1.8%
Italy -- Muslim 1.5%
Norway -- Muslim 1.8%

At 2% to 5%, they begin to proselytize from other ethnic minorities and disaffected groups, often with major recruiting from the jails and among street gangs. This is happening in:

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.
For example, they will push for the introduction of halal (clean by Islamic standards) food.They will increase pressure on supermarket chains to feature halal on their shelves -- along with threats for failure to comply. What makes food halal is the animal must be terrified during slaughter by having it's head slowly cut off. This is occurring in:

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

At this point, they will work to get the ruling government to allow them to rule themselves (within their ghettos) under Sharia, the Islamic Law. The ultimate 
goal of Islamists is to establish Sharia law over the entire world.

When Muslims approach 10% of the population, they tend to increase lawlessness as a means of complaint about their conditions.
In Paris, we are already seeing be-headings. Any non Muslim action offends Islam, and results in uprisings and threats, such as in Amsterdam , with opposition to Mohammed cartoons and films about Islam.
Such tensions are seen daily, particularly in Muslim sections, in:

Guyana -- Muslim 10%
India -- Muslim 13.4%
Israel -- Muslim 16%
Kenya -- Muslim 10%
Russia -- Muslim 15%

After reaching 20%, nations can expect hair-trigger rioting, jihad militia formations, sporadic killings, and the burnings of Christian churches and Jewish synagogues, such as in:

Ethiopia -- Muslim 32.8%

At 40%, nations experience widespread massacres, chronic terror attacks, and on going militia warfare, such as in:

Bosnia -- Muslim 40%
Chad -- Muslim 53.1%
Lebanon -- Muslim 59.7%

From 60%, nations experience unfettered persecution of non-believers of all other religions (including non-conforming Muslims), sporadic ethnic cleansing 
(genocide), use of Sharia Law as a weapon, and Jizya, the tax placed on infidels, such as in:

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

After 80%, expect daily intimidation and violent jihad, some State-run ethnic cleansing, and even some genocide, as these nations drive out the infidels, and move toward 100% Muslim, such as has been experienced and in some ways is on-going in:

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.. Here there's supposed to be peace, because everybody is a Muslim, the Madrasses are the only schools, and the Koran is the only word,
such as in:

Afghanistan -- Muslim 100%
Saudi Arabia -- Muslim 100%
Somalia -- Muslim 100%
Yemen -- Muslim 100%

Unfortunately, peace is never achieved, as in these 100% states the most radical Muslims intimidate and spew hatred, and satisfy their blood lust by killing less radical Muslims, 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; the tribe against the world, and all of us against the infidel. -- Leon Uris, 'The Haj'

It is important to understand that in some countries, with well under 100% Muslim populations, such as France, the minority Muslim populations live in ghettos, within which they are 100% Muslim, and within which they live by Sharia Law.

The national police do not even enter these ghettos. There are no national courts, nor schools, nor non-Muslim religious facilities. In such situations, Muslims do not integrate into the community at large. The children attend madrasses. They learn only the Koran. To even associate with an infidel is a crime punishable with death.

Therefore, in some areas of certain nations, Muslim Imams and extremists exercise more power than the national average would indicate.
Today's 1.5 billion Muslims make up 22% of the world's population. But their birth rates dwarf the birth rates of Christians, Hindus, Buddhists, Jews, and all
other believers.

Muslims will exceed 50% of the world's population by the end of this century.
