Almost all of Vatican City's little more than 800 citizens either live inside the Vatican's walls or serve in the Holy See's diplomatic corps in embassies (called "nunciatures"; a papal ambassador is a "nuncio") around the world.
The Vatican has an efficient health care system that addresses the needs of all those residing within the state. The Vatican Pharmacy known as Farmacia Vaticana was founded in 1874 by Eusebio Ludvig Fronmen. The pharmacy caters to around 2000 customers each day.
The geography of Vatican City is unique due to the country's position as an urban, landlocked enclave of Rome, Italy.
