Current Population of the United States The current U.S.A. population is over 300 million people (324,485,597 as of 2017). The United States has the world's third largest population (following China and India). As the world's population is approximately 7.3 billion, the current United States population represents a mere 4.5% of the world's population. That means that about one in every twenty people on the planet is a resident of the United States of America. In 1790, the year of the first census of the U.S. population, there were 3,929,214 Americans.

- In the US, much of the impact is a result of growing population and faster-growing development of land. Between 1990 and 2000, the U.S. population grew by 33 million people, the greatest increase the country has ever seen. Future growth is predicted to add 27 million people each decade for the next 30 years.he U.S. population constitutes only 5% of world population, but consumes 24% of world's energy. The U.S. is losing 400,000 acres of rural land per year, while urbanized land area increased between 1969 and 1990 at twice the rate of population growth in the same time period.

U.S. Population, 1790-2000: Always Growing After a small rise in the next decade, the decade of the Great Depression gave America its lowest decadal increase ever at 7.2%. Henry A. Wallace wrote in his book New Frontiers in 1934, that the end of population growth in the United States as in sight. Today, immigration is mostly shut out. Our birthrate is decreasing. It appears that by 1950 our population will probably reach its peak, around a hundred and fifty million people, and then start declining.. Wallace was correct about the 1950 census, but otherwise missed the trend. In the postwar period, the Baby Boom reversed the decline.

Lincoln Population 2018 In 2011, census estimates showed that Nebraska's population grew at a faster rate than the U.S. average for the past two years. Nebraska has been growing at a rate of around 1% since 2008, while the U.S. population posted its smallest growth since 1945 of just 0.84%. Nebraska, and Lincoln in particular, are growing as more people move to the area for jobs, as the state has consistently had one of the lowest unemployment rates in the country.
