Society and culture
Notable cultural divides(differences) exist between urban Irish and rural Irish, between the Catholic and Protestant people of Northern Ireland, between the Irish-speaking people and the English-speaking majority population.
Population
As of April 2010, Ireland's estimated population was 4,470,700. The country's population increased significantly(reasonably large in number) in recent years, due to(because of) immigration. In addition, the birth rate in Ireland is currently over double the death rate, which is highly unusual among Western European countries. Approximately 10% of Ireland's population are foreign(from a different country) citizens. The largest group of immigrants comes from the United Kingdom, followed by Poland, Lithuania, Nigeria and Latvia.
Languages
English and Irish are the official languages of Ireland, with English being the dominant(ruling, governing) one. According to the 2006 census, 39% of the population regard themselves as competent in Irish. Road signs are usually bilingual(written in two different languages). Most public notices and print media are in English only. Most Government publications(the communication of information to the general public) are available in both languages. The Polish language is one of the most widely spoken languages in Ireland after English and Irish.
Religion
Ireland's constitution provides for freedom of religion(the right to hold any religious beliefs, and to carry out the practices of any religion). Christianity is the country's predominant religion, with the largest church being the Roman Catholic Church and the second largest being the Church of Ireland. In 2006, 86.8% of the population identified themselves as Roman Catholic, 4.4% described themselves as having no religion, and 1.7% did not respond to the question. According to a study, the country has one of the Western World's highest rates of regular Mass(the principal liturgical service of the Church) attendance. Other significant Protestant denominations are the Presbyterian Church, followed by the Methodist Church.
