Question

Next, research the US population in 2015 on the Internet. Note the total population of the United States, and analyze the population pyramid's

shape. In a short essay, analyze the changes that have taken place to the US population between 1950 and 2015. Based on your knowledge of US
history, why do you think the US population changed as it did in that span of time? What effects do you think these changes have had on the
physical environment of the United States? What do you think will occur between 2015 and 2070?

Answer 1

The population pyramids show that the US population more than doubled in the years between 1950 and 2015 from 150 million to 320 million. Also, the demographic makeup of the population changed. In 1950, young people made up a large percentage of the population and became known as the baby boom generation. This term refers to the increase in people born just after World War II in the United States. In 2015, the population is more evenly divided between ages and genders, although there is a growth in the amount of older Americans, which once again shows the effects of the baby boomers.

The drastic increase in the overall US population undoubtedly has had an impact on the US physical environment. A population that has doubled means that cities and towns have also probably doubled in size on average. Urban sprawl and pollution has become a more serious problem between 1950 and 2015. It doesn’t seem that the population could double again between 2015 and 2070, but the US population will likely continue to grow, resulting in more potential pollution and environmental problems in the United States.

Answer 2

The population of USA in 2015 was 320.7 million.

Step-by-step explanation:

The population of USA in 2015 was 320.7 million. From 1950 to 2015, the population of USA increases because the birth rate in USA is higher than the death rate which results in the increase in population. Due to increase in the population, more vehicles are used and more industries were installed to fulfilled the needs of the present population which results in the pollution of air and the environment is adversely effected. From 2015 to 2070, both population and pollution increases in USA and also in the world.
