The 2020 Census Demographic and Housing Characteristics (DHC) data report released in May found that the Baby Boom generation (born 1946-1964) and Millennials (born 1982-2000), the two largest U.S. cohorts in 2020, continued to age over the last 20 years, however, the number children born between 2010 and 2020 was significantly smaller. The current population pyramid shows the U.S. population now sits at around 330 million, up 22.7 million from 2010. It also indicates that the Baby Boomer population takes up a significant portion of the pyramid, while the number of Millennials and those in their early 20s and 30s have declined. The number of children under the age of 5 has also dropped due to a decrease in birth rates in the U.S.Utah was one of the few states to buck the trend of a greater aging population.
