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. A population pyramid can reveal information about the demographic characteristics, such as birth rate, death rate, life expectancy, and dependency ratio, of a population.
The population pyramid of the United States is based on the data from the U.S. Census Bureau and the World Bank. It shows the projected population of the United States from 2016 to 2060, by sex, race, and age. The population pyramid of the United States has the following features:
– The population pyramid of the United States is broad at the base and narrow at the top, indicating a high birth rate and a low death rate. This means that the population of the United States is growing and young.
– The population pyramid of the United States has bumps and dents in some age groups, reflecting the historical events and migration patterns that affected the population. For example, the baby boomers are the large cohort of people born between 1946 and 1964, who are now in their 60s and 70s. The baby bust is the smaller cohort of people born between 1965 and 1979, who are now in their 40s and 50s. The echo boomers or millennials are the large cohort of people born between 1980 and 2000, who are now in their 20s and 30s.
