No. All of those countries are Christian-majority countries.
As the areas and populations of countries are not in correlation, I can only bring out those countries that have the best population and area ratio. Those would probably be: USA (North-America) and China (Asia)
The Islam Countries are mainly located in Asia, and some can be found in Africa. No one actually knows why they are located in this part of the world, but I would say that they were considered sacred because maybe the prophets had set foot and travelled from Arabia to this land to give them the message, to tell them to worship Allah...maybe these countries think that they are Islamic because of these reasons? I am a Muslim myself, but I don't really know the correct answer. I'm only a kid._______________________________________________________________In the continents of Asia and Africa and some parts of EuropeThere are two main reasons why Islamic countries became Islamic countries. A great number of them (especially those in North Africa, the Middle East, the Balkans, and South Asia) became Muslim-majority countries because they were conquered and ruled by successive Islamic Governments. In these countries, the citizens converted to Islam because of its spiritual benefits, but also because of better employment opportunities for Muslims, better living arrangements for Muslims, and lower taxes for Muslims. There are other Muslim-majority countries (especially in West Africa, East Africa, and Indonesia) that became Islamic due to the trade routes. Muslim merchants met non-Muslims and introduced the non-Muslims to Islam. In many cases, it took and resulted in the establishment of Islamic States outside of the areas that had been conquered by Islamic Armies.Recently, since World War II, the greatest growth of Islam (in national percentages) is happening in Europe, where Muslims are immigrating to in search of economic opportunities not present in their own countries. If this trend continues, Europe will become Islamic not due to conquest or due to proselytization but due to demographic shifts.

In some countries that follow Islamic law, leaving the religion of Islam can be punishable by death.
Answer 1The origins of many of the claimed "post Islamic" religions includes Abrahamic religions. These are those found mainly in Middle Eastern countries.

This all is happening due to the family planning and birth control in those countries that young generation and children are less in number than elderly population which is causing too much difficulties for those countries because number of elderly dependents are increasing in number than working youth and population of those countries is decreasing drastically.
Countries and people on earth are collectively referred to as the global population or world population. Each country has its own distinct name and the people living in those countries are referred to by their nationality or ethnicity.
China has the highest population among those countries, followed by India, the USA, Indonesia, and Brazil.
Do you mean are officially Islamic countries the most numerous in the world? The answer to this is no. There are many countries that have large populations of Muslims however whose governments are not officially Muslim. However, even those consitute a large minority (57 out of 192 countries). However, in the United Nations and other international organizations, the majority-Muslim countries tend to vote as a bloc. Since other minority groups are more liberal and often vote against each other due to particularized interests, this gives the "Islamic bloc" a lot more power than it should have relative to its actual percentage of countries.
Yes, of those three countries, the United States has the largest population, Mexico is second, and Canada is third.
