Average annual percentage increase from 2000 to 2050:
1. The entire US population: 0.61% per year
2. The population 65 and older: 2.09% per year

The total US population is projected to increase from 331 million in 2020 to 379 million in 2050, growing at a decelerating rate.  The population aged 65 and older is projected to grow from 58 million in 2022 to 82 million in 2050.

The impact of immigration is captured by the likelihood that by the early 2030s one third of the workforce will be first or second generation immigrants.
