The correct answer to the question of how many countries are members of the United Nations (UN) is 193. The UN was established in 1945 with the aim to foster international peace and security, promote human rights and social progress, improve living standards, and fight disease. Over the years, the number of member states has grown from the original 51 to the present 193. This number includes most of the world's sovereign states but does not include a few like the Holy See (Vatican City) and Palestine, which hold the status of non-member observer states, nor does it include Taiwan or other disputed regions like Abkhazia and South Ossetia.
