The nation of India contains 1,269,219 square miles within its borders, making it slightly larger than Alaska, Texas and California, the three largest states in the United States, combined. India is about one-third the size of the United States.
Despite its relatively small size, India ranks second in the world in population, with fewer people than only China. At the 2011 census, there were 1,210,193,422 people living in India. This is about four times the number of people living in the United States. The largest city is Mumbai, once called Bombay, with a population of 12.5 million people. India is comprised of 28 states, the largest of which is Uttar Pradesh. If this one state was a nation, it would be the fifth-largest nation in the world in terms of population.
