<h3>What are major changes occurred in America's population?</h3>
In 2006, America's population reached 300,000,000 inhabitants. According to the estimates of the US Census Bureau, at the end of 2019 the American population will exceed 330 million people. As can be seen, it is a population in constant increase, both for its positive birth rate and for the high rates of immigration that arrive in the country every year. With these numbers, a percentage of annual population growth of 0.62% is determined.
This amount of population makes the United States the third most populated country in the world, only behind China and India (which have 1.4 billion and 1.35 billion inhabitants, respectively).
