Answer . A rough estimate: 30 %.
About 15 percent of the world's population is Roman Catholic. Thecountry with the most Catholics is Brazil, followed by Mexico, andthen the United States.
Around 2.1 Billion Christians. that is about 1/3rd the population of the earth or 33.33333333333333333333333 with the three after the decimal place constantly reapeting %. The… largest majority of Christians are Catholic, of which, there are about 1 billion catholics in the world. that is 1/6th of the population.
Roman Catholic Answer That depends on how you define "Christian". The obvious answer is 100% as all Christians are Catholic, even if they are not a visible member of the Chu…rch, if they have been validly baptised and profess the Nicene Creed in its traditional interpretration. Those who call themselves "Christian" but do not belong to the Church have classically been known as heretics, the explanation of which is below. The current usage of the word "Christian" to mean practially anything is to be deplored, it is even used of pagans who display some virtue which could be considered Christian. Those who have been raised in separated faiths, such as protestants, are only material heretics as explained below. from Modern Catholic Dictionary by John A. Hardon, S.J. Doubleday & Co., Inc. Garden City, NY 1980 . Heresy . Commonly refers to a doctrinal belief held in opposition to the recognized standards of an establish system of thought. Theologically it means an opinion at variance with the authorized teachings of any church, notably the Christian, and especially when this promotes separation from the main body of faithful believers. In the Roman Catholic Church, heresy has a very specific meaning. Anyone who, after receiving baptism, while remaining nominally a Christian, pertinaciously denies or doubts any of the truths that must be believed with divine and Catholic faith is considered a heretic. Accordingly four elements must be verified to constitute formal heresy; previous valid baptism, which need not have been in the Catholic Church; external profession of still being a Christian, otherwise a person becomes an apostate; outright denial or positive doubt regarding a truth that the Catholic Church has actually proposed as revealed by God; and the disbelief must be morally culpable, where a nominal Christian refuses to accept what he knows is a doctrinal imperative. Objectively, therefore, to become a heretic in the strict canonical sense and be excommunicated from the faithful, one must deny or question a truth that is taught not merely on the authority of the Church but on the word of God revealed in the Scriptures or sacred tradition. Subjectively a person must recognize his obligation to believe. If he acts in good faith, as with most persons brought up in non-Catholic surroundings, the heresy is only material and implies neither guilt nor sin against faith. (Etym. Latin haeresis , from the Greek hairesis , a taking, choice, sect, heresy.). Of the some 2.2 billion people who are Christians approximately 1.2 billion are Roman Catholic. So slightly more than 50% of Christians are Roman Catholic.
As of 2012, there are 2.4 billion Christians in the world. This is 34 percen t of the world's total population of 6.8 billion people.
As it is hard to exactly measure religious affiliation, and as many organizations have incentives to exaggerate their membership, it is hard to quantify well. Christianity …is still generally thought to be the most popular religion in the world today. Best estimates is that around 2 billion people consider themselves Christian, though obviously not all belong to a specific religion or church. Thus, out of a total world population of 7 billion, this means that about 71% of the world is non-Christian.
Unbelievably, the percentage of the world's population being uneducated, is 46 percent. *Considering that most of the world's population is still involved in farming and oth…er subsistence activities, in villages or smaller social units, the figure of 46 percent is not credible.
According to the CIA World Factbook, out of the total world population of 7.015 billion 13.78% are Hindus. (as of 2009 estimation) Hinduism is growing at around 1.52 pe…rcent annually.
2% of the US population and 4% of the worlds population are red heads
Itis estimated that 1 billion
There's about 2 billion Christians out of the 6 billion people on earth
If you combine Catholics, Protestants and Eastern Orthodox together, believe it or not I think its a solid 60%, the two biggest being Catholic and Orthodox believe it or not. …Orthodox Christians in fact outnumber protestants, because of Russia and the Balkan's massive combined population, however they are not as numerous as Catholics, who can be found in most of Europe, pretty much the whole of Latin America, and throughout Africa.
Sadly very few. 33% call themselves Christians but in reality probably only 19% are true practicing Christians, perhaps less
