The nation experienced a certain shift age distributions over the last decade. With Baby Boomers moving on to retirement, Millennials and Gen Xers began to make up the working population.

To determine where the different demographics are more present, Trulia created a report to see where the youngest and oldest places are in America. The report broke down county demographics into three categories: Young (ages 0-19), working age (ages 20-64) and elderly (65+ years).  After the demographic breakdown, the report compared the population percentages of 2010 and 2017 to show the shift in recent years.

On average, people in the elderly population concentrated towards the South. There was also a significant amount of elderly in the Pacific Northwest and parts of New England.

The youngest generation had the highest population in Utah, rightfully so as they have the highest birth rate.
