A population pyramid is a graphical representation of the age and sex distribution of a population. It shows how many people of each gender and age group are living in a country or region at a given time.
The population pyramid of the U.S. in 2015 was shaped like a column, with a wide base and a narrow top. This indicates that the U.S. had a relatively balanced population structure, with a large number of people in the working-age groups (15-64 years) and a smaller number of people in the dependent groups (under 15 and over 65 years).
The U.S. population pyramid in 2015 also showed some distinctive features, such as:
– The baby boomers, a large cohort of people born between 1946 and 1964, were in the 51-69 age range. They accounted for about 23% of the total population and had a significant impact on the social and economic trends of the country.
– The millennials, a generation of people born between 1981 and 1996, were in the 19-34 age range. They were the largest living generation in the U.S., surpassing the baby boomers in 2015. They represented about 27% of the total population and had diverse characteristics and preferences.
– The immigration effect, which refers to the influence of foreign-born people on the population structure. The U.S. had a high rate of immigration, especially from Latin America and Asia, which contributed to the growth and diversity of the population. The foreign-born population was about 14% of the total population in 2015, and most of them were in the 25-54 age range.
– The gender gap, which means the difference between the number of males and females in a population. The U.S. had a slightly higher number of females than males in 2015, with a sex ratio of 97.1 males per
